Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display method and apparatus for displaying data unevenly distributed in a mathematical space on a display device, and a storage medium used for the data display method and apparatus.

[0002]

2. Description of the Related Art In this type of conventional display device, when displaying data spread over a wide range in space or time, it is necessary to display a data portion that cannot be displayed on the screen of the display device. Are displayed by changing the display area or changing the range of data that can be displayed on one display screen by providing a scroll bar.

For example, there is a timing chart for displaying a history of operation of a mechanical device as a display system.

FIG. 17 is a diagram showing an example of a timing chart for displaying a history of the operation of a conventional mechanical device. In the figure, 161 is a timing chart, 162 is a time scale change box, 163 is a time scale, 164 is a data display screen, 165 is a scroll bar, and 166 is a unit name.

[0005] In the conventional timing chart 161, data of a predetermined time can be displayed by moving the knob of the scroll bar 165. Further, by changing the time scale 163 using the time scale change box 162, the time range of the history displayed on the data display screen 164 can be changed.

[0006]

However, in the above-mentioned conventional example, when displaying data having a feature that data is spread over a wide range and data is unevenly distributed, all data are displayed. Is uniformly handled, so that there is a problem that a blank area is displayed endlessly in some cases.

Moreover, data is unevenly distributed, and data in the unevenly distributed areas have a close relationship with each other, but the unevenly distributed areas have a low mutual relationship when displaying data. In addition, there is a problem that by displaying only the data in the unevenly distributed region, it is not possible to display only the region that the user particularly wants to view.

For example, consider an example of a timing chart for displaying the operation history of a mechanical device. First, it is assumed that the mechanical device is driven, and after the driving is completed, the machine device is rested for a while, and then the mechanical device is driven again to obtain data as shown in FIG. 18 as all data. In FIG. 18, the horizontal axis represents time, and the vertical axis represents each unit. In FIG. 18, 171 is all data,
Reference numeral 172 denotes a first device driving time region indicating a history of operation in a time zone when the mechanical device is first driven, 173 denotes a first post-processing history when the mechanical device is driven for the first time, and 174 denotes a drive of the mechanical device again. A second device driving time region indicating the operation history in the time period in which the operation is performed, 175 is an operation start history, and 176 is an operation end history. Operation start history 175
A line connecting to the operation end history 176 indicates that the unit was operating.

When such data is obtained, it is important for the user that the mechanical device is actually driven in the first device driving time region 172 and the second device driving time region 174. , And the relationship between the device driving time region 172 and the second device driving time region 174 is not important.

In displaying such data, the conventional display of the timing chart 161 treats all data uniformly and displays the histories of all time zones.
When the user wants to display the time region in which the mechanical device has been driven, it is necessary to control the scroll bar 165. In some cases, the control using the scroll bar 165 may display only a blank area in which the mechanical device has not performed any operation.
There was a problem that it was very difficult to see. That is, it is not possible to display only data that the user wants to display that has meaning.

The calculation of the average number 52 of units being executed is performed using a moving average in the present embodiment. The average number 52 of units being executed is obtained as an average of the number of units being executed after the reference time interval 53 from the calculation time of the average number of units being executed. The following formula (1) is used for calculating the average number of units during execution.

[0062]

(Equation 1) Here, Nave is the average number of active units to be obtained, T
Is a reference time interval, i is an identifier representing a unit, max
Is the maximum value of the identifier of the unit, Ti is the time during which the unit represented by the identifier i has been executing during the calculation time of the average number of units being executed ± (1/2) T, and A is the unit of all units. Represents the sum of Ti.

Next, it is determined in step S404 whether or not the grouping is being performed.
At 405, it is determined whether or not the average number of running units (Nave) is equal to or greater than the number specified by the user in the running unit average number specification box 51. If the number is equal to or larger than the specified number, a grouping start process is performed in step S406. The grouping start process is as follows: (1) The current execution unit average number calculation reference time is held as a grouping start time. (2) Set to the grouping state. Is performed.

Thereafter, in step S409, the reference time for calculating the average number of units being executed is incremented by the increment time. The increment time is set in advance. After the increment in step S409, it is determined in step S410 whether the reference time for calculating the average number of units being executed is longer than the last data. If the time is larger, the present processing operation is terminated.

On the other hand, if the grouping is being performed in step S404, it is determined in step S407 whether the average number of running units (Nave) is smaller than the number specified by the user in the running unit average number designation box 51. . If it is smaller, step S40
In step 8, grouping end processing is performed. This grouping end processing is as follows: (1) The current execution unit average number calculation reference time is held as a grouping end time. (2) Set to a state where grouping is not being performed. (3) Register the grouping start time and grouping end time in the database. Is performed.

The format of the database is shown in Table 1 below.

[0067]

[Table 1] The database holds a grouping start time and a grouping end time. In addition, when registering the grouping start time and the grouping end time in the database, in order to prevent both ends from being suddenly cut off at the time of display, the grouping start time = grouping start time−room time (fixed value) grouping end time = Register as grouping end time + margin time (fixed value).

Next, the display processing operation when the user clicks the mouse in the whole display window 34 of FIG. 3 will be described with reference to the flowchart of FIG.

The database is searched in 603 and the next step S60
In step 4, it is determined whether the clicked time calculated in step S602 is grouped.

In step S604, it is determined whether or not grouping has been performed if the clicked time is between the grouping start time and the grouping end time in the database.
Otherwise, it is determined that no grouping has been performed.

If the clicked time is grouped in step S604, the data within the grouped range time is read in the next step S605, and the timing chart is displayed again in the next step S606. This processing operation ends. The redisplay of the timing chart in step S606 is only within the range of the grouped time, and the range that can be displayed by scrolling is the same. If the clicked time is not grouped in step S604, the process proceeds to step S6.
05 and step S606 are skipped, and this processing operation ends.

Next, the display processing operation when the right arrow button 37b of the group skip button 37 in FIG. 3 is pressed by the user will be described with reference to the flowchart in FIG.

First, if the right arrow button 37b of the group skip button 37 is pressed by the user in step S701, the center (middle) time on the screen currently displayed on the timing chart is determined in the next step S702. Ask. Next, the database is searched in step S703, and in the next step S704, it is determined whether or not there is a time zone that is grouped at a time after the center time of the display screen of the current timing chart. And
If there is a time zone that is grouped, in the next step S705, data in a range that is grouped in a time zone that is later than the time at the center of the display screen and is closest to the time at the center of the display screen is read, and the next step S706. After the timing chart is displayed again, the processing operation ends. The redisplay of the timing chart in step S706 is only within the grouped time range, and the range that can be displayed by scrolling is the same. If there is no grouped time zone after the time at the center of the display screen in the step S704, the steps S705 and S7 are performed.
06 is skipped and the present processing operation ends.

(1) In step S701, the user presses the left arrow button 37a of the group skip button 37. (2) In step S704, it is determined whether or not there is a time zone grouped before the time at the center of the display screen. (3) In step S705, data is read in a range that is before the center time of the display screen and is grouped in a time zone closest to the center time of the display screen. In the present embodiment, it is also possible to display a grouped list.

FIG. 8 is a view showing a grouping list display window. In the figure, 81 is a grouping list display window, 82 is a grouping start time, and 83 is a grouping end time.

Next, the display processing operation of the grouping list display window will be described with reference to the flowchart of FIG.

First, in step S901, the database is searched to obtain a grouping start time and a grouping end time, and in the next step S902, the obtained grouping start time and grouping end time are displayed in the grouping list. Further, by changing the grouping start time 82 and the grouping end time 83 in the grouping list display window 81 in FIG. 8, the user can change the grouping range. Thereafter, this processing operation ends.

The same processing as the change of the grouping start time or end time by the user in the grouping list display window 81 of FIG. 8 can be performed from the entire display window 34 of FIG. 3 by the following method.

The user selects the first

The flow of this grouping processing operation is almost the same as that of FIG. 4 described above, but differs from FIG. 4 in the following points. (1) In step S403, the number of units being executed at the reference number of units being executed is calculated. (2) In step S405, it is determined whether or not the number of executing units calculated in step S403 is equal to or greater than the number specified by the user in the average number of executing units specification box 51. (3) In step S407, it is determined whether or not the number of executing units calculated in step S403 is equal to or less than the number specified by the user in the average number of executing units specification box 51. (4) In step S409, the running unit average number calculation reference time is set as the time of the history next to the history set as the running unit average number calculation reference time. (5) In step S410, it is determined whether or not the next history exists.

In this embodiment, the user can select a unit to be displayed by using the display unit designation box shown in FIG. 10, 101 is a display unit designation box, 102 is a check button, 1
03 is a unit name.
