Abstract

PROBLEM TO BE SOLVED: To easily recognize data on a different display as the same data even through they are displayed in a different state. SOLUTION: A hair line cursor 15 is moved by a pointer 14 so that the hair line cursor 15 in an XY plot 3 indicates this data element 21. Thus, an area 21a in a data table 2 that the retrieved data among a data group are displayed becomes a display state different from others by revising its display state such as being inversely displayed, etc.

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 for displaying the same data in association with each other while displaying the same data group in different forms.

[0002]

2. Description of the Related Art In recent years, process control apparatuses have been implemented on a computer basis, and the use of a window-type graphical user interface (GUI) for displaying control status has been increasing. G like this
By using the UI, it has become possible to see a large number of screens indicating the control state and the like as needed. If the process data is displayed graphically, the process control and its management can be simplified.

[0003] The method of displaying process data can be roughly classified into two types: a method of displaying graphics and a method of displaying data tables. With a graphic display method such as a trend or an XY plot, a correlation between data can be intuitively expressed. Among them, a trend expressing a change tendency of time-series data is often used. In the case of an XY plot, a quality control chart (SPC), etc., data can be processed or subjected to calculations to express certain characteristics of the data (analysis graphic). On the other hand, in the case of displaying a data table such as a spreadsheet, the accuracy of the displayed data is high, and the data can be easily reprocessed.

[0004]

By the way, in process control, it is necessary to monitor the entire process data and to precisely manage partial fine data. However, in the above-described graphics display, data cannot be displayed with high accuracy, and it is difficult to reprocess data. In the data table display, it is difficult to intuitively recognize the correlation between the displayed data. However, as described above, if the display of the trend data and the display of the data table or the analysis data are simultaneously performed by the multi-window display, it is possible to respond to the above-described request in the process control.

However, conventionally, there has been a problem that it takes a long time to determine the correspondence between the trend data composed of the same original data and the display of the analysis graphic or the like, since the mutual correspondence is not clear. For example, it is determined that some data is abnormal based on the display of the XY plot, but it takes a lot of trouble to find out which part of the trend corresponds to the data, and it becomes clear when the data has occurred. It took time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and when displaying the same data in different states, it is easy to determine that the data is the same even if the display is different. The purpose is to be able to recognize.

[0007]

According to the data display method of the present invention, a data element represented by a graphic display in which a data element is represented by a point or a set of points or a length or area on a predetermined coordinate series is displayed. When selected, the display state of the corresponding numerical value in the data table in which the numerical values of the data are arranged is changed. Thus, other relevant items of the data element are indicated. Further, in the data display method of the present invention, when numerical data in the data table display in which the numerical values of the data are arranged is selected, the elements of the data are represented by points or a set of points or a length or area on a predetermined coordinate series. The cursor is arranged at the display position of the corresponding data element in the graphic display shown. Therefore, the association with other data is visually indicated. And
According to the data display method of the present invention, when a point of a data element shown in the first graphic display is selected, a cursor is arranged at a display position of a corresponding data element in the second graphic display. Therefore, the relationship with other data is shown in a different form.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. Hereinafter, a first embodiment of the present invention will be described. In the process control device, the control state and the like are shown on a plurality of screens as shown in FIGS.
As shown in FIGS. 1 and 2, during the display indicating the control state, the process trend window 1 is displayed as a graphic, while the data table 2 including a regression analysis table is displayed.

In the window of the process trend window 1, for example, the window of the XY plot 3 is displayed.
The window name is displayed in the title area 11 at the top of the window, and the menu area 12 immediately below the title area 11 is
A menu for inputting various instructions such as file operations is displayed. A function button 13 for realizing functions such as displaying graphic data is provided below the menu area 12 of the process trend window 1.
Is arranged. Then, the pointer 14 is moved by a mouse operation or the like, and is arranged on the function button 13.
By turning on the mouse switch in this state, the function assigned to the function button 13 can be developed.

[0010] Hereinafter, in the state displayed as described above,
Details of each data element in the display of the XY plot 3
A case where the data table 2 is displayed so as to be referred to will be described. For example, as shown in FIG. 1, the XY plot 3 includes only one data element 21 in a state different from the others.
There is. Here, the hairline cursor 15 is moved by the pointer 14 so that the hairline cursor 15 in the XY plot 3 points to this data element 21.
As a result, the CPU constituting the process control device
Specifies the data element (for one record) at the specified location,
Search is performed from the data group displayed in the data table 2.

Then, the CPU operates the area 21a of the data table 2 in which the searched data in the data group is displayed.
The display mode is changed by, for example, inverting the display to make the display state different from the others. The change of the display state is not limited to the reverse display, but may be a change of a display color, a higher display brightness than another area, or the like. As described above, if you want to know more detailed information, etc., in the process trend window 1 displayed graphically,
What is necessary is to select the point of the data element in the XY plot 3 displaying the desired data with the hairline cursor. As a result, the corresponding data in the data table 2 which is displayed separately is displayed in reverse video, for example, and more detailed information can be obtained quickly.

Next, a case where the desired data is displayed in the XY plot 3 in the data table 2 will be described. For example, as shown in FIG. 2, the pointer 14 is moved to the row of No. 36 while the data table 2 is being displayed. Then, the CPU constituting the process control device calculates the display coordinates of the data at the designated location in the XY plot 3. Then, the CPU moves the hairline cursor 15 to the calculated coordinate position. As described above, the display position of the designated data in the data table 2 in the XY plot 3 is indicated by the hairline cursor 15, and the position of the corresponding element 21 can be immediately known.

Embodiment 2 FIG. Hereinafter, a second embodiment of the present invention will be described. In the first embodiment, the data table is associated with the graphic display. However, the present invention is not limited to this, and the graphic displays may be associated with each other. FIGS. 3 and 4 show a state in which two windows of a trend graph 4 expressing a change tendency of time-series data and an XY plot 3 (scatter plot) expressing characteristics of process data are displayed in an overlapping manner. I have. The trend graph 4 and the XY plot 3 are generated from the same process data. 3 and 4
Are the same as those in FIGS.

In the second embodiment, first, as shown in FIG. 3, the hairline cursor 15 is overlapped by moving the pointer 14 to a certain element data 21 in the XY plot 3. As a result, the CPU constituting the process control device displaying the data retrieves the data element (for one record) at the specified location from the process data. Next, the CPU calculates where the searched data is displayed in the trend graph 4. Then, as shown in FIG. 4, the CPU displays the trend graph 4 on the entire surface, moves the hairline cursor 16 in the trend graph 4 to the calculated coordinate position in the trend graph 4, and displays the same. As a result, it is immediately known where the element data 21 selected in the XY plot 3 is located in the trend graph 4.

[0015]

As described above, according to the present invention, a point of a data element shown in a graphic display in which a data element is represented by a point or a set of points or a length or area on a predetermined coordinate series is selected. Then, the display state of the corresponding numerical value in the data table in which the numerical values of the data are arranged is changed. Further, when numerical data in the data table display in which the numerical values of the data are displayed is selected, the corresponding data in the graphic display in which the elements of the data are represented by points or sets of points or lengths and areas on a predetermined coordinate series are displayed. The cursor is now placed at the display position of the element. Then, when the point of the data element shown in the first graphic display is selected, the cursor is arranged at the display position of the corresponding data element in the second graphic display.

As described above, for example, other items related to the data element are indicated, and the relation with other data is visually indicated. Even if the same data is shown in different display states, the same data will be shown in association. Therefore, according to the present invention, there is an effect that the same data can be easily recognized even in different displays.
