Display waveform shows picture 20.The waveform, which is shown, not only shows signal waveform W1, W2 based on measurement Value Data Dw in picture 20,
Also display is for specifying the cursor of any part in two signal waveforms W1, W2 to show 21.
In this case, waveform shown in Fig. 4~12 referred in Fig. 2 and later is shown in picture 20, using following
Picture structure: " measurement moment (by the time) " and an example as " first direction " for making an example as " the first parameter "
The direction of arrow AL, AR is corresponding, and make " signal level " as an example of " the second parameter " with as with " first direction " phase
It hands over the direction of arrow BU, BD of an example of " second direction " of (orthogonal) corresponding, is based on measurement Value Data Dw so as to show
Signal waveform W1, W2 etc..
In addition, cursor shows that 21 be as specifying the time-axis direction in signal waveform W1, W2 etc. " signal waveform "
Any point (position at " any measurement moment " of an example as " arbitrary parameter value ") on (direction of arrow AL, AR)
The display (time shaft cursor is shown) for marking and playing a role, the Waveform display apparatus 2 (program data Dp) of this example is in display unit
At the time of 13 display waveforms show picture 20, show that the central part in picture 20 on time-axis direction is aobvious in waveform as shown in figure
Show that cursor shows 21.
The Waveform display apparatus 2 (program data Dp) of this example is using such as flowering structure: signal waveform W1, W2 is equivalent to " signal
Either in waveform and specified display ", and cursor shows that 21 are equivalent to " another party in signal waveform and specified display ", leads to
Crossing makes cursor show that 21 move in signal waveform W1, W2, shows 21 by cursor to specify the time in signal waveform W1, W2
Any point in axis direction.
In this case, for example, by two signal waveforms W1, W2 respectively zero crossing at the time of be set as " singular point ", want it is true
When being somebody's turn to do the measurement moment (passing through the time) of " singular point " calmly, need that cursor is made to show 21 alignment intersection location Px.But as in the figure
Shown in waveform show the example of picture 20, signal level can with signal waveform W1 that the very short period dramatically changes,
When W2 etc. is shown on waveform display picture 20, according to display multiplying power set by the moment, signal waveform W1, W2 can be showed
Line state intensive in picture, so that it is determined that cursor show 21 " singular points " to be aligned (in this example for intersection location Px) this
Body is with regard to highly difficult.
Thus, the Waveform display apparatus 2 (program data Dp) of this example is configured to for example refer to show 21 by cursor
When determining any point on the time-axis direction of signal waveform W1, W2 and moving cursor and show 21, mobile light can be carried out simultaneously
" the change of display multiplying power on " moving operation " of mark display 21 and the arbitrarily time-axis direction of change signal waveform W1, W2
Operation ".Thus, it is possible to reliably and easily see intersection location Px, and cursor can be made to show that 21 is mobile to intersection location Px.
Specifically, as shown in Fig. 2, showing that 21 are shown in waveform display picture 20 in signal waveform W1, W2 and cursor
In the state of, it carries out showing any point on 21 as the drag operation of starting point using cursor using operation portion 12 (touch screen).
In this case, the Waveform display apparatus 2 (program data Dp) of this example is for example as shown in Figure 3 along the side of arrow C
When carrying out drag operation as starting point to the position P0 shown on 21 using cursor and arriving position P1, the determination of processing unit 14 arrow C direction
Along the operation component A 01 (" first of the time-axis direction (direction of arrow AL, AR) as " first direction " in drag operation
Operate component " an example) direction and size show that cursor 21 relative to signal and according to identified direction and size
Waveform W1, W2 are moved on time-axis direction.
Specifically, showing that cursor 21 relative to signal waveform when operating component A 01 is the component in the direction arrow AL
W1, W2 are moved along the direction of arrow AL, and when operating component A 01 is the component in the direction arrow AR, cursor are made to show 21
It is moved relative to signal waveform W1, W2 along the direction of arrow AR.When operation component A 01 is smaller, cursor is made to show that 21 is opposite
It is slightly moved in signal waveform W1, W2, when operation component A 01 is larger, cursor is made to show that 21 is big relative to signal waveform W1, W2
Amplitude shift is dynamic.In the example for carrying out drag operation shown in the figure to the direction arrow C, operation component A 01 is the behaviour in the direction arrow AR
Make component, therefore processing unit 14 makes cursor show that 21 move to the direction arrow AR relative to signal waveform W1, W2 and operate component
The corresponding amount of movement of the size of A01.
Processing unit 14 also shows that 21 movement concurrently maintains to be shown specified by 21 in signal waveform W1 as cursor with cursor
A little and signal waveform W2 in as cursor show 21 specified by be a little respectively displayed on waveform display picture 20 in state,
And along the signal level axis direction (side of arrow BU, BD as " second direction " in the drag operation in the determining direction arrow C
To) operation component B01 (an example of " second operation component ") direction and size, become according to identified direction and size
Display multiplying power on the time-axis direction of more signal waveform W1, W2.
Specifically, when operating component B01 is the component in the direction arrow BU, direction amplified signal waveform along the time axis
W1, W2 (display multiplying power becomes larger), when operating component B01 is the component in the direction arrow BD, direction reduces signal along the time axis
Waveform W1, W2 (display multiplying power becomes smaller).In addition, reducing the display multiplying power of signal waveform W1, W2 when operation component B01 is smaller
Amount of change, when operate component B01 it is larger when, increase signal waveform W1, W2 display multiplying power amount of change.Shown in the figure to
The direction arrow C carries out in the example of drag operation, and operation component B01 is and the operation point in the amplification direction the corresponding arrow BU in direction
Amount, thus processing unit 14 with the corresponding amount of change of the operation size of component B01 along the time axis direction amplified signal waveform W1,
W2。
In this case, the Waveform display apparatus 2 (program data Dp) of this example uses following structure and processing method:
When carrying out above-mentioned drag operation, when " the component ratio " of the size of the size and " the second operation component " of " the first operation component " is low
When " prespecified threshold value ", do not change the display multiplying power of signal waveform W1, W2, when " component ratio " is " threshold value " or more,
According to the direction of " the second operation component " and size, the display multiplying power of signal waveform W1, W2 is changed.Specifically, for example, by using
Following structure and processing method: when above-mentioned " component ratio " is lower than " 1/3 ", i.e. the size of " the second operation component " is lower than
The size of " first operation component " 1/3 when, the display multiplying power of signal waveform W1, W2 is maintained, when " component ratio " is more than " 1/3 "
When, i.e., the size of " the second operation component " changes signal waveform W1, W2 at 1/3 or more of the size of " the first operation component "
Display multiplying power.
The Waveform display apparatus 2 (program data Dp) of this example also uses following structure and processing method: above-mentioned in progress
Drag operation when, every the prespecified period (such as the period at the interval 50ms), determine respectively " first operation component " and
" second operation component ", and the direction that operates component according to identified two and size come carry out cursor show 21 movement with
The change of the display multiplying power of signal waveform W1, W2.
Thus, such as waveform shown in Fig. 2 shows the intensive state of line of such signal waveform W1, W2 of example of picture 20
Under, it is difficult to when determining that cursor shows the 21 intersection location Px to be aligned, firstly, showing any point on 21 as starting point using cursor
Start drag operation to the direction arrow U.
At this point, size and side of the processing unit 14 according to " the second operation component " into the drag operation in the direction arrow BU
To direction amplified signal waveform W1, W2 along the time axis as illustrated in fig. 4.To show picture compared to waveform shown in Fig. 2
The state in face 20 becomes the state of the intersection location Px in more easily determining signal waveform W1, W2.Due to dragging for the direction arrow BU
It drags in operation and " the first operation component " is not present, therefore processing unit 14 does not move cursor and shows 21, keeps its display position not
Become.
In addition, processing unit 14 is according to " the second behaviour in the drag operation when the drag operation in the direction arrow BU continues
Make component " direction and size, signal waveform W1, W2 is further amplified in direction along the time axis as illustrated in fig. 5.To phase
Than the state for showing picture 20 in waveform shown in Fig. 4, becomes and be more easier to determine the intersection location Px in signal waveform W1, W2
State.
Moreover, it is as shown in the drawing, it is being amplified to the intersection location that can reliably and easily determine in signal waveform W1, W2
In the state of the display multiplying power of Px, cursor is made to show that 21 is mobile to identified intersection location Px.Specifically, shown in the figure
Example in, due to being that cursor shows 21 states being located on the right side of intersection location Px, towing in the direction above-mentioned arrow BU
After operation, finger without departing from touch screen (operation portion 12) carries out drag operation to the direction arrow AL.
At this point, size and side of the processing unit 14 according to " the first operation component " into the drag operation in the direction arrow AL
To so that cursor is shown 21, direction is mobile to the direction arrow AL along the time axis relative to signal waveform W1, W2.The waveform of this example is aobvious
Showing device 2 (program data Dp) is as described above in the size and the size of " the second operation component " of " the first operation component "
When " component ratio " is lower than " 1/3 ", the display multiplying power of signal waveform W1, W2 is not changed, therefore pulled to the direction arrow AL
When operation, micro " the second operation component " is generated even if finger slightly adipping is mobile, signal waveform W1, W2 is shown
Show that multiplying power will not change, but maintains the state shown with identical display multiplying power.
So that the state that cursor shows 21 is overlapped on intersection location Px as shown in fig. 6, can be realized, to realize logical
Cross cursor show 21 come specify signal waveform W1, W2 intersection location Px state.Thus, be judged as by cursor show 21 come
The user that the movement of specified intersection location Px is completed terminates drag operation, and finger leaves touch screen.At this point, as shown in fig. 7, processing
Portion 14 maintains by cursor to show that 21 specify the state of intersection location Px, and the display before being started with above-mentioned drag operation is again
Rate shows signal waveform W1, W2.As a result, by cursor show 21 come specify signal waveform W1, W2 intersection location Px work
Industry is completed, the measured value of the intersection location Px in signal waveform W1, W2 or measurement moment (passing through the time) and signal waveform W1, W2
Waveform is shown in together to show on picture 20 (not shown).
The Waveform display apparatus 2 (program data Dp) of this example uses following structure and processing method: carrying out above-mentioned drag
During draging operation, no matter the display multiplying power of signal waveform W1, W2 is great display multiplying power, all in finger contact touch screen
Display highlighting shows 21 on position.That is, drag operation is from starting knot in the Waveform display apparatus 2 (program data Dp) of this example
During beam, cursor corresponding to the per unit operating quantity of pointing device shows that 21 show picture 20 in waveform on time-axis direction
Amount of movement on interior time-axis direction keeps certain, and unrelated with the display multiplying power of signal waveform W1, W2.
In addition, this example Waveform display apparatus 2 (program data Dp) use following structure and processing method: using by
External device (ED) constitute pointing device come replace touch screen carry out drag operation when, drag operation carry out during, no matter signal
The display multiplying power of waveform W1, W2 are great display multiplying powers, also all show picture in waveform in the operation by pointing device
Display highlighting shows 21 on the display position of the pointer (not shown) shown on 20.That is, using external device (ED) pointing device when,
Drag operation from start to end during, waveform corresponding to the per unit operating quantity of pointing device is shown on time-axis direction
Cursor shows that 21 amount of movement is also kept centainly on time-axis direction in picture 20, and the display multiplying power with signal waveform W1, W2
It is unrelated.
In this case, it is using with the structure and processing method of the Waveform display apparatus 2 (program data Dp) of this example not
With as in the case where flowering structure and processing method, i.e., during drag operation, every list of pointing device on time-axis direction
Waveform corresponding to bit manipulation amount shows that cursor shows 21 amount of movement and signal waveform W1, W2 on time-axis direction in picture 20
The linkage variation of display multiplying power in the case where, signal waveform is made according to the direction of " second operation component " in drag operation and size
W1, W2 along the time axis direction amplification display when, waveform corresponding to the per unit operating quantity of pointing device is shown in picture 20
Cursor on time-axis direction shows that 21 amount of movement will increase.
In such structure and processing method, although making intersection location Px's by amplification display signal waveform W1, W2
Determine that transfiguration is easy, but under the state (state of amplification display) that can be readily determined intersection location Px, as long as along the time
Axis direction slightly drags, and cursor will be made to show that 21 substantially move on time-axis direction.Therefore, it is possible to which cursor is caused to show
21 are difficult to be directed at intersection location Px.
In this regard, the Waveform display apparatus 2 (program data Dp) of this example drag operation from start to end during, even if
Under the state (state of amplification display) that can be readily determined intersection location Px, every list of pointing device on time-axis direction
Waveform corresponding to bit manipulation amount shows that the cursor in picture 20 on time-axis direction shows that 21 amount of movement also maintains and towing
Movement start at the time of identical amount of movement it is constant, therefore, when direction slightly drags along the time axis, cursor show 21 to when
Between axis direction it is somewhat shifted, when direction substantially drags along the time axis, cursor shows that 21 substantially move to time-axis direction.From
And cursor can easily be made to show 21 alignment intersection location Px.
It is explained above when showing that any point on 21 carries out drag operation as starting point using cursor, is grasped according to the towing
Display multiplying power on time-axis direction of the direction and size of " second operation component " in work to change signal waveform W1, W2
Example, but when carrying out drag operation to the direction arrow BU in the same manner as above-mentioned example, it can also be shown using waveform shown in Fig. 8
Structure as the example of picture 20 and processing method: according to the direction of " the second operation component " in the drag operation and greatly
It is small, change the display multiplying power on the time-axis direction and the two directions of signal level axis direction of signal waveform W1, W2.
About the above-mentioned display for showing signal waveform W1, W2 etc. in any one drag operation lighted on 21 with the cursor
The change of multiplying power can pre-select " only changing the display multiplying power on time-axis direction (first direction) " and " change time shaft
Any one in display multiplying power on direction (first direction) and signal level axis direction (second direction) the two directions ".
On the other hand, different from showing by cursor the state of intersection location Px that 21 specify signal waveform W1, W2
Aforesaid operations example, signal waveform W3 shown in Fig. 9 are wanting to determine the measurement for being somebody's turn to do " singular point " using leading edge position as " singular point "
When the moment (passing through the time), need that cursor is made to show leading edge position Pu shown in 21 alignment Figure 10~12.But it is shown in Fig. 9
Waveform shows in picture 20 that, when the display multiplying power of signal waveform W3 is excessive, leading edge position Pu is just no longer shown.Therefore, when
The display multiplying power of signal waveform W3 etc. is larger and leads to leading edge position Pu etc. " singular point " when no longer showing, is shown first with cursor
Any point on 21 starts drag operation to the direction arrow BD for starting point.
At this point, processing unit 14 is according to the direction of " second operation component " into the drag operation in the direction arrow BD and big
Small, direction reduces signal waveform W3 along the time axis as illustrated in fig. 10.To become the leading edge position in signal waveform W3
Pu shows the state shown in picture 20 in waveform, it can be seen that leading edge position Pu.Due to the drag operation in the direction arrow BD
In there is no " first operation component ", therefore processing unit 14 does not move cursor and shows 21, remains unchanged its display position.
In addition, making in the state of narrowing down to the display multiplying power that can determine the Pu of the leading edge position on signal waveform W3
Cursor shows that 21 is mobile to identified leading edge position Pu.Specifically, in the example shown in the figure, due to being that cursor is aobvious
Show 21 states being located on the right side of leading edge position Pu, therefore after the drag operation in the direction above-mentioned arrow BD, finger without departing from
Touch screen (operation portion 12) drag operation is carried out to the direction arrow AL.At this point, processing unit 14 is according to dragging to the direction arrow AL
The size and Orientation for draging " the first operation component " in operation, makes cursor show that 21 is square along the time axis relative to signal waveform W3
It is moved to the direction arrow AL.
To as shown in figure 11, can be realized the overlapping cursor on leading edge position Pu and show 21 state, to realize
By cursor show 21 come specify signal waveform W3 leading edge position Pu state.Thus, it is judged as and shows 21 by cursor
User to specify the movement of leading edge position Pu to complete terminates drag operation, and finger leaves touch screen.At this point, such as Figure 12 institute
Show, processing unit 14 maintains by cursor to show that 21 specify the state of leading edge position Pu, and before being started with above-mentioned drag operation
Display multiplying power show signal waveform W3.21 are shown by cursor as a result, to specify the leading edge position Pu of signal waveform W3
Operation is completed, the measured value of the leading edge position Pu in signal waveform W3 or measurement moment (passing through the time) and signal waveform W3 mono-
And it is shown in waveform and shows on picture 20 (not shown).
In this case, it is using with the structure and processing method of the Waveform display apparatus 2 (program data Dp) of this example not
With as in the case where flowering structure and processing method, i.e., during drag operation, the unit of pointing device on time-axis direction
Waveform corresponding to operating quantity shows in picture 20 that cursor on time-axis direction show that 21 amount of movement and signal waveform W3 are shown
In the case where showing multiplying power linkage variation, the edge signal waveform W3 is made according to the direction of " the second operation component " and size in drag operation
Time-axis direction when reducing display, waveform corresponding to the per unit operating quantity of pointing device shows time shaft side in picture 20
Upward cursor shows that 21 amount of movement will be reduced.
In such structure and processing method, rising can determine although realizing by diminution display signal waveform W3
Along the state of position Pu, but cursor shows that 21 are moved to the towing behaviour that identified leading edge position Pu needs to carry out very long range
Make, or needs to carry out multiple drag operation.Therefore, it is possible to which cursor is caused to show that 21 alignment leading edge position Pu will expend very
For a long time.
And in the Waveform display apparatus 2 (program data Dp) of this example, as described above, the phase of drag operation from start to end
Between, the Waveform display apparatus 2 (program data Dp) of this example is on time-axis direction corresponding to the per unit operating quantity of pointing device
Waveform show in picture 20 that cursor on time-axis direction show identical shifting when keeping starting with drag operation of 21 amount of movement
Momentum is constant, and unrelated with the display multiplying power of signal waveform W3.Therefore, cursor can be easily made to show that 21 are moved to rising edge
Position Pu.
On the other hand, it in the Waveform display apparatus 2 (program data Dp) of this example, as shown in figure 13, can be shown in waveform
Signal waveform W1, W2 are shown on picture 20 together and for example as specifying the signal level axis side in signal waveform W1, W2
The cursor that the index of upward any part (another example of " arbitrary parameter value " is " any measured value position ") plays a role is aobvious
Show 21a (signal level axis cursor is shown), to replace as specifying the time in signal waveform W1, W2 or signal waveform W3
The cursor that the index at any point in axis direction plays a role shows 21.
In this case, Figure 13 and Figure 15 referred to later, waveform shown in 16 show that picture 20 uses following picture
Structure: make another " signal level " as " the first parameter " and another arrow BU, BD as " first direction "
Direction is corresponding, and intersects " measurement moment (by the time) " of an example as " the second parameter " with as with " first direction "
Another direction arrow AL, AR of " second direction " of (orthogonal) is corresponding, and can show signal based on measurement Value Data Dw
Waveform W1, W2 etc..Figure 13 show waveform show picture 20 on just shown cursor show 21a after, waveform show picture
Central part (position that signal level value is " 0 ") display highlighting of 20 signal level axis direction (direction arrow BU, BD) is shown
The state of 21a.
In this case, such as wanting to determine the value of the maximum value in signal waveform W1 shown in the figure and measuring the moment
When (passing through the time), need that cursor is made to show that 21a is directed at the peak position Pp as " singular point ".But as shown in the figure
Waveform shows the example of picture 20, can be shown in signal level with signal waveform W1, W2 etc. that the very short period dramatically changes
Show that, according to display multiplying power set by the moment, the line that can show signal waveform W1, W2 exists when waveform is shown on picture 20
Intensive state in picture, so that it is determined that cursor shows 21a " singular point " to be aligned (being peak position Pp in this example) inherently
It is highly difficult.
Thus, with it is above-mentioned make cursor show 21 be directed at intersection location Px drag operation when it is the same, utilize operation portion 21 (touching
Touch screen) show that any point on 21a carries out drag operation as starting point using cursor.
In this case, along the side of arrow C shown in Waveform display apparatus 2 (program data Dp) such as Figure 14 of this example
To when showing that the position P0 of a on 21 carries out drag operation to position P2 as starting point using cursor, the determination of processing unit 14 direction arrow C
Along the operation component B02 of the signal level axis direction (direction of arrow BU, BD) as " first direction " in drag operation
The direction of (an example of " the first operation component ") and size, and according to identified direction and size, so that cursor is shown that 21 is opposite
It is moved in signal level axis direction in signal waveform W1, W2.
Specifically, making cursor show 21a relative to signal wave when operating component B02 is the component in the direction arrow BU
Shape W1, W2 is moved along the direction of arrow BU, and when operating component B02 is the component in the direction arrow BD, shows cursor
21a is moved relative to signal waveform W1, W2 along the direction of arrow BD.When operation component B02 is smaller, cursor is made to show 21a
It is slightly moved relative to signal waveform W1, W2, when operation component B02 is larger, cursor is made to show 21a relative to signal waveform
W1, W2 are substantially moved.In the example for carrying out drag operation shown in the figure to the direction arrow C, operation component B02 is the arrow side BU
To operation component, therefore processing unit 14 makes cursor show that 21a is mobile to the direction arrow BU relative to signal waveform W1, W2 and grasps
Make the corresponding amount of movement of size of component B02.
Processing unit 14 also shows that the movement of 21a concurrently maintains to show that 21a is signified by cursor in signal waveform W1 with cursor
Fixed a little and in signal waveform W2 as cursor shows that waveform is a little respectively displayed on specified by 21a to be shown in picture 20
State, and along the time-axis direction (side of arrow AL, AR as " second direction " in the drag operation in the determining direction arrow C
To) operation component A 02 (an example of " second operation component ") direction and size, according to identified direction and size come point
It Bian Geng not display multiplying power in the display multiplying power and time-axis direction in the signal level axis direction of signal waveform W1, W2.
Specifically, when operating component A 02 is the component in the direction arrow AR, along signal level axis direction and time shaft
Direction amplified signal waveform W1, W2 (display multiplying power becomes larger), when operating component A 02 is the component in the direction arrow AL, along letter
Number level axis direction and time-axis direction reduce signal waveform W1, W2 (display multiplying power becomes smaller).In addition, when operation component A 02 compared with
Hour, reduce the amount of change of the display multiplying power of signal waveform W1, W2, when operation component A 02 is larger, increase signal waveform W1,
The amount of change of the display multiplying power of W2.In the example for carrying out drag operation shown in the figure to the direction arrow C, operation component A 02 is
With amplification the direction the corresponding arrow AR in direction operation component, therefore processing unit 14 with operation the size of component A 02 it is corresponding
Amount of change is along signal level axis direction and the two directions of time-axis direction amplified signal waveform W1, W2.
In this case, the Waveform display apparatus 2 (program data Dp) of this example uses following structure and processing method:
When carrying out above-mentioned drag operation, when " the component ratio " of the size of the size and " the second operation component " of " the first operation component " is low
When " prespecified threshold value ", do not change the display multiplying power of signal waveform W1, W2, when " component ratio " is " threshold value " or more,
According to the direction of " the second operation component " and size, the display multiplying power of signal waveform W1, W2 is changed.Specifically, for example, by using
Following structure and processing method: when above-mentioned " component ratio " is lower than " 1/3 ", i.e. the size of " the second operation component " is lower than
The size of " first operation component " 1/3 when, the display multiplying power of signal waveform W1, W2 is maintained, when " component ratio " is more than " 1/3 "
When, i.e., the size of " the second operation component " changes signal waveform W1, W2 at 1/3 or more of the size of " the first operation component "
Display multiplying power.
Thus, such as waveform shown in Figure 13 shows the intensive shape of line of such signal waveform W1, W2 of example of picture 20
Under state, it is difficult to when determining that cursor shows the 21a peak position Pp to be aligned, show any point on 21a as starting point using cursor
Start drag operation to the direction arrow C.
At this point, direction and size of the processing unit 14 according to " the first operation component " into the drag operation in the direction arrow C,
Make cursor show 21a moved along signal level axis direction to the direction arrow BU relative to signal waveform W1, W2, and according to
The direction of " the second operation component " in the drag operation in the direction arrow C and size, make signal waveform W1, W2 along signal level
Axis direction and the amplification of the two directions of time-axis direction.To as shown in figure 15, show picture compared to waveform shown in Figure 13
20 state becomes the state for being more easier to determine the peak position Pp in signal waveform W1, W2, and becomes cursor and show 21
The state being moved near peak position Pp.
Then, continue drag operation towards the peak position Pp of the signal waveform W1 of amplification display.To which cursor is aobvious
Show that 21a is overlapped on peak position Pp, realizes and 21a is shown by cursor to specify the shape of the peak position Pp of signal waveform W1
State.Thus, it is judged as that the user for showing 21a by cursor to specify the movement of peak position Pp to complete terminates drag operation, hand
Finger leaves touch screen.At this point, as shown in figure 16, processing unit 14 maintains to show that 21a specifies the shape of peak position Px by cursor
State, and display multiplying power before being started with above-mentioned drag operation shows signal waveform W1, W2.21a is shown by cursor as a result,
The operation of the peak position Pp of signal waveform W1, W2 is specified to complete, the measured value of the peak position Pp in signal waveform W1, W2
Or the measurement moment (passing through the time) is shown in waveform with signal waveform W1, W2 together and shows on picture 20.
It is explained above when showing that any point on 21a carries out drag operation as starting point using cursor, according to the towing
The direction of " second operation component " in operation and size change the signal level axis direction and time shaft of signal waveform W1, W2
The example of display multiplying power on the two directions of direction, but in the same manner as above-mentioned example to the direction arrow C carry out drag operation when,
It can also be using following setting: according to the direction of " the second operation component " in the drag operation and size, changing signal waveform
Display multiplying power in the signal level axis direction of W1, W2.
As a result, in the Waveform display apparatus 2, processing unit 14 signal waveform W1, W2 ... and cursor shows 21,21a
Be shown in the state that waveform shows in picture 20, by the pointing device touch screen of operation portion 12 (in this example be) carry out with
Cursor show any point on 21,21a be starting point drag operation when, according in drag operation along " first direction "
The direction of " first operation component " and size, make wherein a side (show 21,21a in this example for cursor) relative to another party (
Be signal waveform W1, W2 in example ...) it is mobile along " first direction ", and maintain signal waveform W1, W2 ... in by light
" position of arbitrary parameter value " specified by mark display 21,21a is shown in the state in waveform display picture 20, also according to towing
In operation along " second direction " " second operation component " direction and size come change signal waveform W1, W2 ... it is aobvious
Show multiplying power.In program data Dp, above-mentioned processing is executed by the processing unit 14 of Waveform display apparatus 2.
Thus, according to the Waveform display apparatus 2 and program data Dp, shown in picture 20 being difficult to see that waveform is shown
Signal waveform W1, W2 ... in " position (singular point) of arbitrary parameter value ", signal waveform W1, W2 ... display multiplying power mistake
It is big and when causing waveform to show in picture 20 without display " singular point ", by a drag operation can and meanwhile to above-mentioned
" singular point " mobile cursor show 21,21a and change signal waveform W1, W2 ... display multiplying power operation.Thus, energy
It is enough that cursor is easily made to show that 21,21a is shown in the " position (surprise of arbitrary parameter value in signal waveform W1, W2 in a short time
Point) ".
According to the Waveform display apparatus 2 and program data Dp, drag operation from start to end during, pointing device to
Waveform corresponding to the per unit operating quantity of " first direction " shows that cursor shows 21,21a to " first direction " in picture 20
Amount of movement is all kept centainly, thus be different from signal waveform W1, W2 ... display multiplying power it is bigger, the per unit of pointing device
Cursor corresponding to operating quantity show the bigger amount of movement of 21,21a or signal waveform W1, W2 ... display multiplying power get over
Small, cursor corresponding to the unit operation amount of pointing device shows the fewer structure and processing method of the amount of movement of 21,21a, and
Be can with signal waveform W1, W2 ... the independently corresponding amount of movement wanted mobile cursor and show 21,21a of display multiplying power
Pointing device is operated, so as to which cursor is reliably and easily shown that 21,21a is moved to that " position of arbitrary parameter value is (odd
Point) ".As a result, signal waveform W1, W2 ... amplification display in the state of be not in be difficult to show cursor 21,21a
The state that position is finely adjusted, or signal waveform W1, W2 ... will not occur in the state of reducing display in order to make light
The case where mark shows the mobile a degree of distance of 21,21a and increases operating quantity (or number of drag operation) of pointing device,
Cursor can be reliably set to show that 21,21a is moved to the " position (singular point) of arbitrary parameter value."
Moreover, being started according to the Waveform display apparatus 2 and program data Dp at the end of drag operation with drag operation
Preceding display multiplying power come show signal waveform W1, W2 ..., to show that 21,21a is targeted by " arbitrary parameter value in cursor
Changed when position (singular point) " signal waveform W1, W2 ... display multiplying power in the case where, also can be before recovery operation
Display multiplying power shows the operation that multiplying power is restored without make.
In addition, size and " the second behaviour according to the Waveform display apparatus 2 and program data Dp, when " the first operation component "
Make component " size component than lower than prespecified threshold value (being " 1/3 " in this example) when, do not change signal waveform W1,
W2 ... display multiplying power, when component ratio is threshold value or more, according to the direction of " second operation component " and size, change letter
Number waveform W1, W2 ... display multiplying power, thus just to change signal waveform W1, W2 ... display multiplying power and into
To in the case where the drag operation for the adipping for slightly exist " the first operation component " when capable drag operation,
Can not move cursor change with showing 21,21a signal waveform W1, W2 ... display multiplying power.
The structure of " Waveform display apparatus " is not limited to the structural example of above-mentioned Waveform display apparatus 2.For example, being explained above makes
Cursor show 21,21a relative to signal waveform W1, W2 ... it is mobile to show that 21,21a specifies signal wave by cursor to realize
The structure of the state of " singular point " in shape W1, W2 and the example of processing method, but can also be using will be as " signal waveform and referring to
Either in fixed display " cursor show that the display position of 21,21a is fixed in advance, make as " signal waveform and specified showing
In another party " signal waveform W1, W2 show the mobile structure of 21,21a relative to the cursor.
In addition, during drag operation is explained above from start to end, unit of the pointing device to " first direction "
Waveform corresponding to operating quantity shows that cursor shows that 21,21a keeps certain knot to the amount of movement of " first direction " in picture 20
The example of structure, but can also " waveform shows picture using making corresponding to per unit operating quantity of the pointing device to " first direction "
The amount of movement of face " interior " specified display " to " first direction " is corresponding with " the display multiplying power of signal waveform ", and " display multiplying power " is got over
Greatly, " amount of movement corresponding to per unit operating quantity " is bigger, " display multiplying power " smaller, " amount of movement corresponding to unit operation amount "
Smaller structure.
Show 21,21a as " specified display " and signal waveform the cursor of linear (linear) in addition, being explained above
The example for the structure that W is shown together, but the shape of " specified display " is without being limited thereto, can also be shown using dotted (circle), is each
The structure (not shown) that the display of kind mark and graphics shape is shown as " specified display ".In addition, being explained above
Display multiplying power before being started at the end of drag operation with drag operation show signal waveform W1, W2 ... structure example
Son, but can also be using the structure for the display multiplying power for maintaining this moment at the end of drag operation.
In addition, the letter of measurement device 1 and display based on measurement Value Data Dw for generating measurement Value Data Dw is explained above
Number waveform W1, W2 ... the example that is separately constructed of Waveform display apparatus 2, but can also using " Wave data " generation and
The display of " signal waveform " based on " Wave data " is performed structure by single device.Specifically, being surveyed shown in Figure 17
