Description

  The present invention relates to a display control device, a display control method, and a display control program.

  The operation terminal displays the analysis data detected and analyzed by the analyzer as a waveform in a display area on a display screen of a display device such as a display. The operator of the operation terminal visually analyzes the displayed waveform and performs data analysis. The operation terminal receives input of operations such as an analysis condition setting instruction and analysis data display instruction from an operator via a GUI (Graphical User Interface).

  The display area is an area on the display screen where the waveform display is drawn. For example, the display area is set inside a window frame on the display screen.

  The display range is a waveform display range displayed in the display area. For example, it is assumed that the X axis is 0 to 1 million and the Y axis is 0 to 600,000 for the entire waveform display range. When the entire waveform display is divided vertically and horizontally by 2 × 2 = 4 and the upper left range is displayed, the display range is from the start point (0,600,000) to the end point (500,000,300,000). Thus, when the display range is a rectangle, the display range is represented by a set of a start point (upper left point) and an end point (lower right point).

  The information that can be displayed in the display area on the display screen is limited by the size (number of inches) and resolution (number of pixels) of the display, and thus is limited information. Therefore, the operator performs data analysis from the waveform display by performing a display range changing operation for changing from the current display range to the display range desired by the operator (desired range) without changing the size of the display area.

  In the display range change operation, the display range to be displayed is specified directly (absolute specification) regardless of the current display range, and the display range to be displayed is specified by changing the current display range. It is classified into a method (relative specification). Since the operator rarely knows the desired range in advance, the operator searches for the desired range by trial and error in which the current display range is repeatedly changed by relative designation.

  The display range change operation by relative designation is "moving operation" that slides the vertical and horizontal of the display range without changing the size of the current display range, and by making the display range to be displayed wider than the current display range, Enlarge the waveform displayed in the current display range by reducing the waveform displayed in the current display range and by reducing the display range to be displayed from now on. "Enlargement operation" is mentioned.

As an example of the reduction operation, the technique described in Patent Document 1 is such that when an object displayed in the display area is moved outside the display area while dragging, the object is reduced and the entire display area is reduced. indicate.
JP-A-9-305344

  In order to reduce the burden of trial and error for displaying the desired range in the display area, it is necessary to reduce the number of display range changing operations.

  First, in the enlargement operation, when the desired range can be confirmed to be small in a part of the current display area, when the display area displaying the desired range is selected using a pointing device such as a mouse, the selected area is displayed. The corresponding designated range is enlarged and displayed over the entire display area as a new display range. At this time, the desired range can be displayed by one enlargement operation.

  On the other hand, in the reduction operation, not all of the desired range is displayed in the current display area, so it is difficult to specify the desired range in one reduction operation. As a result, the number of operations for changing the display range increases excessively due to excessive reduction and enlargement again.

  Accordingly, the main object of the present invention is to reduce the burden of trial and error for displaying the operator's desired range in the display area on the display screen.

In order to solve the above problems, the present invention is a display control device for displaying a waveform display region for displaying a waveform of analysis data on a display device in accordance with an input operation input via an input device,
The display control device has an analysis control unit and an analysis data analysis unit,
The analysis controller analyzes the sample injected into the analyzer acquires the waveform of the analysis data, while when held in the X-axis of the waveform of the analytical data, two-dimensional and signal strength to the Y-axis Or a two-dimensional spectroscopic graph having a wavelength on the X axis and a signal intensity on the Y axis of the waveform of the analysis data is displayed in the waveform display area,
The analysis data analysis unit
When the designated area is input to the waveform display area by the input operation, the X axis and the Y axis of the display range of the analysis data currently displayed in the waveform display area are within the display range corresponding to the designated area. Reducing the waveform of the analysis data displayed in the waveform display area by displaying the waveform display area outside the specified area displayed in a reduced size so as to fit in
When a designated area is input on the X-axis scale displayed outside the waveform display area, the X-axis of the display range is reduced to the display range corresponding to the X-axis of the designated area , and Display the reduced X-axis outside the specified area,
When the designated area is input on the Y-axis scale displayed outside the waveform display area, the Y axis of the display range is reduced to the display range corresponding to the Y axis of the designated area , and The reduced Y axis outside the designated area is displayed . Other means will be described later.

  According to the present invention, the display range of the currently displayed display area is stored in the designated area. As a result, the reduction size and the reduction position are designated by one input operation of the designated area, and it is possible to reduce the burden of trial and error for displaying the operator's desired range in the display area on the display screen. .

  Hereinafter, an analysis system according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a configuration diagram showing an analysis system.

  The analysis system is configured by connecting the operation terminal 101 and the analysis apparatus 102 with a communication cable 103. The operation terminal 101 is a computer such as a personal computer. The analyzer 102 is, for example, an amino acid analyzer, a high-performance liquid chromatograph device, a mass spectrometer, or a spectrophotometer that performs quantitative / qualitative analysis of amino acid composition.

  The analyzer 102 will be described by taking an amino acid analyzer as an example. The analysis apparatus 102 detects a solvent supply unit 115 for supplying a solvent for carrying a sample to be analyzed, an injection unit 116 for injecting the sample, a separation unit 117 for separating each component from the sample, and each component of the separated sample. The detection unit 118 detects the waveform of the analysis data in time series. Furthermore, the analysis apparatus 102 includes a control unit 113 for controlling each component and a communication processing unit 114 for communicating with the operation terminal 101.

  Note that a column is used for the separation unit 117. The sample injected into the column has a difference in the time spent in the column depending on the type of each component constituting the sample. For example, when a sample is composed of three components, the time spent in the column of each of the three components is different from each other. As a result, if the X axis of the analysis data is the holding time and the Y axis is the signal intensity, it is expected that three peaks corresponding to the three components appear as waveforms.

  The operation terminal 101 includes a central processing unit 109 that controls the operation terminal 101, a hard disk 108, a RAM (Random Access Memory) 110 that temporarily stores analysis data, and a communication device 112 that communicates with the analysis apparatus 102. Connected to the operation terminal 101 are a display 104 for displaying a waveform, a keyboard 105 for inputting characters, and a mouse 106 for inputting a specified range. The operation terminal 101 includes an input / output control unit 107 that controls the keyboard 105 and the mouse 106, and an internal bus 111 that connects the components of the operation terminal 101 to each other.

  The hard disk 108 stores an operating system, control driver software for controlling the display 104, the keyboard 105, and the like, software for controlling the analysis apparatus 102, software for analyzing analysis data, and the like. As the operating system of the operation terminal 101, for example, Windows (registered trademark) is activated, and each software stored in the hard disk 108 operates as an application activated on Windows (registered trademark).

  FIG. 2 is a configuration diagram illustrating the operation terminal.

  The operation terminal 101 includes an analysis control unit 201 for creating and analyzing analysis conditions, and an analysis data analysis unit 202 for analyzing analysis data. Each of these components is implemented as software, for example, and is realized by being executed by a CPU (Central Processing Unit) of the operation terminal.

  First, the analysis control unit 201 creates an analysis condition for executing the analysis and stores it in the analysis condition DB 203. Next, the analysis control unit 201 selects an analysis condition for executing the analysis from the analysis condition DB 203 and generates a command group for controlling the analysis apparatus 102 based on the selected analysis condition. The analysis control unit 201 transmits the generated command group to the analysis device 102.

  The analyzer 102 performs sample analysis based on the received command group. Further, the analysis apparatus 102 transmits the analysis progress and analysis data obtained in the analysis process to the analysis control unit 201. The analysis control unit 201 stores the analysis data obtained from the analysis apparatus 102 in the analysis data storage DB 204 together with the analysis conditions.

  The analysis control unit 201 displays the analysis data obtained from the analysis apparatus 102 and the progress status in an output column such as a progress display column or a result display column on the display 104.

  The analysis data analysis unit 202 selects and displays analysis data from the analysis data storage DB 204. The analysis data analysis unit 202 outputs the analysis conditions to an output field such as an analysis condition display field on the display 104 and an analysis data to an output field such as a waveform display field on the display 104. The operator executes data analysis based on information displayed in the output column of the analysis data analysis unit 202.

  FIG. 3 is an explanatory diagram showing a waveform display column of analysis data. In the waveform display column for displaying analysis data, the retention time is plotted on the X axis and the intensity is plotted on the Y axis.

  FIG. 3A shows a display area when the display range is the entire analysis data. In the display area 304, the display range is the entire analysis data, and an entire image of the waveform is displayed. The designation area 305 on the display area 304 is designated by a drag operation or the like by the operator using a pointing device such as a mouse.

  FIG. 3B is a display area in which a part of the display range of FIG. The display area 301 displays a two-dimensional waveform by an X-axis scale display area 302 that displays an X-axis scale and a Y-axis scale display area 303 that displays a Y-axis scale. The display range of the display area 301 is a range designated by the designation area 305. That is, when the designated area 305 to be enlarged is selected in the display area 304, the display range corresponding to the designated area 305 is enlarged and displayed in the display area 301.

  The position and size of the designated area 305 in the display area 304 can be changed by a drag operation or the like. In conjunction with the change of the designated area 305, the display range of the display area 301 is updated, and the display area 301 displays the updated display range. Further, the display area 301 changes the scale axes and scales of the X-axis scale display area 302 and the Y-axis scale display area 303 in conjunction with the change of the display range, and adapts to the display contents.

  Further, the display area 301 displays the latest display range when the display range is changed one after another by a display range changing operation described later. The history information of the display range changing operation may be stored in the storage unit, and the display range changing operation may be redone (undoed). Thereby, when the desired range cannot be designated by the reduction operation, it is easy to return to the display range before the reduction operation, and the number of operations can be reduced.

  FIG. 4 is a flowchart showing the waveform display process.

  In the flowchart of FIG. 4, when the operator performs an enlargement / reduction operation (drag operation) in the waveform display field using the mouse, a drag operation is performed from the input / output control unit 107 to the central processing unit 109. It starts from a state where an event indicating this is notified.

  First, the designated area is detected. When notified of the drag operation, the central processing unit 109 detects the coordinates (start point) where the drag operation is started (S1). Further, the central processing unit 109 detects the coordinates (end point) at which the drag operation is ended (S2). The rectangular area from the start point to the end point is the designated area.

  Next, it is determined whether the designation of changing the display range is two-dimensional (X-axis and Y-axis) or one-dimensional (X-axis or Y-axis). Specifically, the central processing unit 109 determines whether or not the starting point of the drag operation is within the display area 301 (S3), and when it is within the display area 301 (S3, Yes) When it is not in the display area 301 (S3, No), it is assumed to be one-dimensional.

  First, the change of the two-dimensional display range will be described. The central processing unit 109 determines whether or not a modifier key (shift key or the like) on the keyboard has been continuously pressed during the drag operation (S10). If the key is held down (S10, Yes), the two-dimensional reduction operation is performed. When (S11) is not kept pressed (S10, No), a two-dimensional enlargement operation (S12) is executed.

  On the other hand, the change of the one-dimensional display range will be described. The central processing unit 109 determines whether or not a modifier key (shift key or the like) on the keyboard has been continuously pressed during the drag operation (S20). If the key is held down (S20, Yes), a one-dimensional reduction operation is performed. When (S21) is not kept pressed (S20, No), a one-dimensional enlargement operation (S22) is executed.

  In S21 and S22, when a drag operation is performed in the Y-axis scale display area 303 in the display area, only the Y-axis is enlarged or reduced. On the other hand, when a drag operation is performed in the X axis scale display area 302, only the X axis is enlarged or reduced.

  Here, the two-dimensional enlargement operation (S12) is to set the display range displayed in the designated area as the display range to be displayed in the entire display area. The two-dimensional reduction operation (S11) will be described later.

  Further, the one-dimensional enlargement operation (S22) is to set either the X axis or Y axis range of the designated area as a new display range and not change the other display range. The one-dimensional reduction operation (S21) will be described later.

  FIG. 5 is an explanatory diagram showing a two-dimensional reduction operation (S11). FIG. 5A shows a display area before the reduction operation, and FIG. 5B shows a display area after the reduction operation.

  In the display area 601 in FIG. 5A, when the operator starts a drag operation using the mouse while holding down the shift key, a designated area 603 appears as the mouse moves from the drag operation start point (X1, Y1). . The operator changes the rectangular area size and position of the designated area 603 while executing the drag operation, and determines the drag operation end point (X2, Y2) so that the designated area 603 becomes the desired area.

  When the designated area 603 in FIG. 5A is determined, the display range displayed in the designated area 603 is displayed on the entire display area 601 in FIG. 5B. In other words, the display range of the display area 601 displayed in FIG. 5A is reduced to the display range of the designated area 603 that appears by the drag operation. That is, since the display range of FIG. 5B includes the display range of FIG. 5A, FIG. 5B is a reduction operation with respect to FIG. In addition, analysis data around the designated area 603 is also displayed outside the designated area 603 in FIG.

  FIG. 6 is an explanatory diagram showing a one-dimensional reduction operation (S21) only on the X axis. FIG. 6A shows a display area before the reduction operation, and FIG. 6B shows a display area after the reduction operation.

  On the X-axis scale outside the display area 801 in FIG. 6A, a designated area 803 from the drag operation start point (X3, Y3) to the drag operation end point (X4, Y4) is determined by the drag operation.

  When the designated area 803 in FIG. 6A is determined, the display area 801 in FIG. 6B shows the display range displayed in the display area 801 in FIG. The analysis data is displayed by changing to an area 804 which is the same as the X axis 803 and whose range in the Y axis direction is the same as the Y axis of the display area 801 in FIG. That is, the display range of the display area 801 in FIG. 6A is reduced and displayed only in the width in the X-axis direction of the designated area 803 selected by the drag operation. Also, analysis data around the designated area 804 is displayed outside the designated area 804 in FIG.

  FIG. 7 is an explanatory diagram showing a one-dimensional reduction operation (S21) only for the Y-axis. FIG. 7A shows a display area before the reduction operation, and FIG. 7B shows a display area after the reduction operation.

  On the Y-axis scale outside the display area 901 in FIG. 7A, a designated area 903 from the drag operation start point (X5, Y5) to the drag operation end point (X6, Y6) is determined by the drag operation.

  When the designated area 903 in FIG. 7A is determined, the display range displayed on the Y axis of the designated area 903 is displayed on the entire display area 901 in FIG. 7B.

  When the designated area 903 in FIG. 7A is determined, the display area 901 in FIG. 7B is the designated area in which the display range displayed in the display area 901 in FIG. The analysis data is displayed by changing to an area 904 that is the same as the Y-axis 903 and whose range in the X-axis direction is the same as the X-axis of the display area 901 in FIG. That is, the display range of the display area 901 in FIG. 7A is reduced and displayed only in the width in the Y-axis direction of the designated area 903 selected by the drag operation. Further, analysis data around the designated area 904 is also displayed outside the designated area 904 in FIG.

  In each of the three types of reduction operations described above, each designated area that appears by a drag operation determines the display range, so that the contrast between the display range before reduction and the display range after reduction becomes visual. There is a high possibility that the display range becomes the desired range by this one reduction operation.

  As described above, the waveform display control method of the present invention is particularly effective in the following cases.

  FIG. 8 is an explanatory diagram showing a display region of a chromatogram displayed by the high performance liquid chromatograph and the amino acid analyzer.

  A display area 1002 displays the entire display range after reduction including the display range specified in the specification area 1001 before reduction. In the display area 1002 before reduction, the peak P1 is displayed, but the peak P2 is not displayed. On the other hand, the reduced display area 1002 displays the peak P1 and the peak P2. The operator can analyze by confirming both the peak P1 and the peak P2 in one display area 1002.

  Note that when the display range after reduction is smaller than the entire display range, reducing the display range to the whole requires display of extra information other than the peak P1 and the peak P2, instead of the peak P1. And the discovery of peak P2 is hindered. Therefore, in order to perform highly accurate analysis, rather than displaying the entire display range, a waveform including the peak P1 of interest and a neighboring peak P2 outside the display range is displayed in the display region 1002. Is preferable.

  FIG. 9 is an explanatory diagram showing a display region of a mass spectrum displayed by the mass spectrometer. As in FIG. 8, in order to find the peak P4 in the vicinity of the focused peak P3, by designating the designated region 1003, the peak P3 and the peak P4 are displayed in the same display region 1004, and the two peaks The display of extra information other than is suppressed.

  In order to assert the remarkable effect of the reduction operation by the designated area described above, a comparison with a comparative example is performed. Comparative examples are the following (1) to (4).

  As a comparative example (1), there is a comparative example in which the history information of the previous enlargement operation is returned to the display range before the enlargement operation (undo). In this comparative example, when there are many enlargement histories, it is necessary to repeat the undo operation many times in order to display the desired range in the display area. On the other hand, in the reduction operation using the designated area, the desired range is displayed in the display area with a small number of operations without depending on the number of past operation histories.

  As a comparative example (2), there is a comparative example in which the display range is reduced to a display range that covers the entire analysis data. In this comparative example, after making the display range as a whole, it is necessary to perform an enlargement operation to make the display range a desired range. However, when the entire analysis data is displayed, a characteristic graph shape such as a peak in the desired range becomes too small to be lost, so it is difficult to make the display range the desired range. On the other hand, in the reduction operation using the designated area, since a characteristic graph shape such as a peak is already found and then reduced, the desired range is displayed in the display area with a small number of operations.

  As a comparative example (3), there is a method (absolute specification) in which a display range to be displayed is designated directly by numerical input or the like regardless of the current display range. In this comparative example, an operator who does not know the desired range in advance does not know how the waveform is displayed in the display area because he / she inputs the numerical value of the display range without guessing. Numerous operations are required. On the other hand, in the reduction operation using the specified area, the display range to be displayed is specified by changing the current display range (relative specification), so the display range candidates can be narrowed down efficiently, and there are few operations. The desired range is displayed in the display area by the number of times.

  As a comparative example (4), there is a method of enlarging / reducing by fixing the center position of the currently displayed display range by dragging with a mouse or the like using an enlargement / reduction scroll bar as in the case of software handling a map. It is done. In this comparative example, for example, even when checking whether or not there is a peak on the right side of the peak currently located, not only the right side of the peak but also the left side of the peak is reduced in the display range. So it is not easy to use. On the other hand, in the reduction operation using the designated area, not only the size (scale) of the display range but also the position can be designated by a single operation, so that the desired range is displayed in the display area with a small number of operations.
