  FIG. 5 is a flowchart showing the overall flow of the graph display process in the statistical calculation mode executed by the CPU 11 provided in the electronic computer 10.

  FIG. 6 is a flowchart showing a plot graph generation process accompanying the graph display process in the statistical calculation mode in the electronic computer 10.

(Data input)
FIG. 7 is a diagram showing an example of the list input screen 21 associated with the graph display process in the statistical calculation mode in the electronic computer 10.

  First, when the user operates the “Menu” key 12 c provided in the key input unit 12 of the electronic computer 10 to set the statistical calculation mode, the list input as shown in FIG. 7 is performed on the display unit 13 under the control of the CPU 11. A screen 21 is displayed (step A1).

  As shown in FIG. 7, a list (table) 22 including a plurality of cells is provided on the list input screen 21. When the user operates the numerical value / symbol key 12a of the key input unit 12 to input numerical data into each cell of the list 22, list data (statistical data) including these numerical data is created (step) A2).

  At this time, when the “Color” key 12e provided in the key input unit 12 is operated, a color selection of red (Red), blue (Blue), green (Grn), and yellow (Yllw) is performed at the lower end of the list input screen 21. A menu 23 is displayed, and an arbitrary color can be designated for each numerical value by operating the function key “Fn” corresponding to each color of the selection menu 23.

  Here, it is assumed that the function key “F2” is operated in red, the function key “F3” is operated in blue, the function key “F4” is operated in green, and the function key “F5” is operated in yellow.

  In the example of FIGS. 7 and 3, the numerical value data “156” input to the fourth cell of List1 is blue, the numerical value “96” input to the seventh cell is red, and the List2 The numerical data “60” input to the fourth cell of FIG. 8 is red, the numerical data “40” input to the seventh cell is blue, and the numerical data “62” input to the eighth cell. Red is specified for.

  Note that the specified color described in the lead-out line in the numerical data in FIG. 7 is given for convenience because it cannot be expressed by coloring due to restrictions in the drawing. In fact, the same numerical data is colored with the specified color. Is displayed.

  In this way, when an arbitrary color is designated for each numerical data of the list data (Yes in step A3), the designated color is set as the attribute information in the numerical data and stored in the list data in the RAM 15. It is stored in the area 15c (step A4).

  If no color is specified, black is assumed to be the default color for the numerical data.

(Graph display based on list data)
After the creation of the list data, when the “Graph” key 12f provided in the key input unit 12 is operated, a graph type selection menu (not shown) showing graph types such as “Scatter”, “Histgram”, and “Regression graph” ) Are displayed along the bottom of the screen, and an arbitrary graph type can be selected by operating the function key “Fn”.

  “Scatter” means plotting the coordinate point specified by the X value and the Y value on the XY coordinate, and the graph drawn by the plotted point is “plot graph” or “ This is called a “scatter diagram”.

  Here, in the case of “Scatter”, the user designates two sets of list data as an X value and a Y value, and performs an operation of instructing drawing of a plot graph (scatter diagram).

  FIG. 8 is a diagram showing a display screen 31 of the plot graph 32X when “Scutter” is selected in accordance with the graph display processing in the statistical calculation mode of the electronic computer 10 and the display color standard is selected as the “X” graph. is there.

  FIG. 9 is a diagram showing a display screen 31 of the plot graph 32Y when “Scutter” is selected in accordance with the graph display processing in the statistical calculation mode of the electronic computer 10 and the display color standard is selected as the “Y” graph. is there.

  When an operation for instructing drawing of a plot graph (scatter diagram) is performed (Yes in step A5), the display color standard of each plot point is set to “X” or “Y” by the user at the lower end of the graph display screen 31. The reference selection menu 24 for selecting “X & Y” is displayed (step A6).

  When the user performs a selection operation on the reference selection menu 24 displayed on the graph display screen 31 (Yes in Step A7), the process proceeds to the plot graph generation process in FIG. 6 to generate a plot graph (Step AB). .

  When “X” is selected in the reference selection menu 24 (Yes in step B1), each cell is handled from the list data <list 1> <list 2> to be graphed stored in the list data storage area 15c. A pair of numerical data is fetched in order. Then, a plot graph is generated in which the (X, Y) points corresponding to the pair of numerical data are sequentially plotted in the color designated by the numerical data of “X” <list 1>, and the data of the plot graph is generated. Is stored in the graph data storage area 15d of the RAM 15 (steps B2 to B4).

  That is, as shown in the graph display screen 31 of FIG. 8, the plot points 33a to 33j in which the numerical data of <List 1> are “X” and the numerical data of <List 2> are “Y” are drawn. The plot graph 32X is generated based on the color specified for each numerical data of the <List 1>. Specifically, the plot point (156, 60) 33d corresponding to the fourth cell is blue, The plot point (96, 40) 33g corresponding to the seventh cell is drawn in red, and the others are drawn in black.

  On the other hand, when “Y” is selected in the reference selection menu 24 (Yes in Step B5), the list data to be graphed <List 1> <List 2> stored in the list data storage area 15c as described above. A pair of numerical data corresponding to each cell is sequentially fetched. Then, a plot graph is generated in which the (X, Y) points corresponding to the pair of numerical data are sequentially plotted in the colors designated in the numerical data of “Y” <list 2>, and the data of the plot graph is generated. Is stored in the graph data storage area 15d of the RAM 15 (steps B6 to B8).

  That is, as shown in the graph display screen 31 of FIG. 9, the plot points 33a to 33j in which the numerical data of <List 1> are “X” and the numerical data of <List 2> are “Y” are drawn. The plot graph 32Y is generated based on the color specified for each numerical data of the <List 2>. Specifically, the plot point (156, 60) 33d corresponding to the fourth cell is red, The plot point (96, 40) 33g corresponding to the seventh cell is drawn in blue, the plot point (122, 62) 33h corresponding to the eighth cell is drawn in red, and the others are drawn in black.

  Further, when “X & Y” is selected in the reference selection menu 24 (Yes in Step B9), list data to be graphed <List 1> <List 2> stored in the list data storage area 15c as described above. A pair of numerical data corresponding to each cell is sequentially fetched from (Step B10), and each time, the color specified in the numerical data of <List 1> and the numerical data of <List 2> are read out. It is determined whether or not the designated color is the same color (step B11).

  If it is determined that the colors are the same (Yes in step B11), a plot graph is generated in which the points (X, Y) corresponding to the pair of numerical data are sequentially plotted in that color. Data is stored in the graph data storage area 15d of the RAM 15 (steps B10 to B13).

  On the other hand, when it is determined that the color specified in the numerical data of <List 1> read out from the list data for each cell is different from the color specified in the numerical data of <List 2> (in step B11) No), a plot graph is generated by plotting (X, Y) points corresponding to the pair of numerical data in a special manner, and the data of the plot graph is stored in the graph data storage area 15d of the RAM 15 ( Steps B10, B11 (No), B14, B13).

  Specifically, the plot points 33a to 33c corresponding to the first to third cells, the plot points 33e, 33f, and the ninth and tenth cells corresponding to the fifth and sixth cells. The plot points 33i, 33j are black, and the plot points 33d, 33g, 33h are drawn in a special manner, corresponding to the fourth, seventh, and eighth cells.

  FIG. 10 shows plot points 33A and 33B in a special mode that are drawn when “X & Y” in the reference selection menu 24 is selected in accordance with the plot graph generation processing of the electronic computer 10 and the designated colors of the numerical data are different. FIG.

  The plot points in the special mode may be frame-shaped plot points 33A having a hole in the center as shown in FIG. 10A, for example, or half different in two colors as shown in FIG. 10B. Alternatively, the frame-shaped plot points 33B may be color-coded.

  When the series of plot graph generation processes ends (Return), the plot graph stored in the graph data storage area 15d is expanded in the display data storage area 15a, and a graph display screen as shown in FIG. 8 or FIG. 31 is displayed in color on the screen of the display unit 13 (step A8).

(Color change after graph display)
Here, after the graph is displayed, when the user operates the “Color” key 12e provided in the key input unit 12 (Yes in Step A9), the graph display screen 31 displays red (Red), blue A (Blue), green (Grn), and yellow (Yllw) color selection window (not shown) is displayed.

  When one color in the color selection window is designated by the operation of the cursor key 12i (Yes in Step A10), the color of the entire graph is changed to the designated color (Step A11). Accordingly, the color designated for each numerical data of the list data stored in the list data storage area 15c of the RAM 15 is similarly changed (step A12).

  At this time, if “X” in the standard selection menu 24 is selected in the plot graph generation process (see FIG. 6), all the colors specified in each numerical data of <List 1> are selected as the color selection. When the color is changed to the designated color in the window and “Y” is selected in the standard selection menu 24, all the colors designated in the numerical data in <List 2> are designated in the color selection window. Changed to Further, when “X & Y” of the same standard selection menu 24 is selected, all the colors designated in the numerical data of <List 1> <List 2> are changed to the designated colors in the color selection window. The

  For example, as shown in FIG. 8, when the “Color” key 12e is operated in a state where the plot graph 32X when the display color standard is selected as the “X” graph is displayed, the color selection (not shown) is performed. When a window is displayed and blue (Blue) in the color selection window is designated by the operation of the cursor key 12i, all the plot points 33a to 33j constituting the plot graph 32X are changed to blue.

  Then, all the colors designated in the numerical data of the list data <list 1> corresponding to the display color reference “X” are changed to blue.

  Further, for example, as shown in FIG. 9, when the “Color” key 12e is operated in a state where the plot graph 32Y when the display color reference is selected as the “Y” graph is displayed, it is not illustrated. If a color selection window is displayed and red (Red) in the color selection window is designated by operating the cursor key 12i, all the plot points 33a to 33j constituting the plot graph 32Y are changed to red.

  Then, all the colors designated in the numerical data of the list data <list 2> corresponding to the display color standard “Y” are changed to red.

  The same applies to the graph corresponding to the “regression graph”, and the color of the graph is changed to the color specified in the color selection window, and the color change is selected as the display color reference in the reference selection menu 24. This is reflected in all the numerical data and the color is changed in the same manner.

-Partial change On the other hand, after the "Color" key 12e is operated (Yes in Step A9), when the "Trace" key 12g is operated instead of the function key "Fn" (Step A13), the graph display screen 31 is displayed. A red (Red), blue (Blue), green (Grn), and yellow (Yllw) color selection window (not shown) is displayed, and a partial color change is performed in the following procedure.

  Since the electronic computer 10 is not provided with a touch panel, when the trace mode is switched by operating the “Trace” key 12g, the object being displayed by the operation of the cursor key 12i (that is, a point on the graph, etc.) ) Are designated one by one.

  FIG. 11 is a diagram showing a display screen 31 of a plot graph 32X in the case where a partial color change is performed by the “Trace” key 12g in accordance with the graph display processing in the statistical calculation mode of the electronic computer 10.

  Here, when the “Trace” key 12g is operated (Yes in Step A13), if the currently displayed graph type is a plot graph, it is selected by operating the cursor key 12i, for example, as shown in FIG. The plotted point 33g on the plotted graph 32X is extracted as a color change target, and is identified and displayed by blinking or the like (step A14).

  Then, list data <list 1> <list 2 in which numerical data [X = 96] [Y = 40] corresponding to the plot point 33g selected by operating the cursor key 12i is stored in the list data storage area 15c. > (See FIG. 3), and displayed in red and blue of the colors specified in the numerical data (step A15).

  Thereafter, when one color in the color selection window (not shown) is designated by operating the cursor key 12i (Yes in step A16), the color of the extracted plot point 33g is the designated color. (Step A17), and accordingly, the color of the corresponding data in the numerical data of the list data stored in the list data storage area 15c of the RAM 15 is also changed (Step A18).

  At this time, in the plot graph generation process (see FIG. 6), if “X” in the standard selection menu 24 is selected, it is designated as the numerical data of <List 1> corresponding to the selected plot point. If only the selected color is changed to the color specified in the color selection window and “Y” in the same reference selection menu 24 is selected, the numerical data of <List 2> corresponding to the selected plot point is displayed. Only the designated color is changed to the designated color in the color selection window. Further, when “X & Y” in the same reference selection menu 24 is selected, the colors specified in the numerical data of <List 1> and <List 2> corresponding to the selected plot point are the color selection window. Changed to the color specified in.

  That is, in the graph display screen 31 of the plot graph 32X in which the display color standard shown in FIG. 11 is selected as “X” <list 1>, the plot point 33g currently displayed in red is the color change target (object). ) And blue (Blue) in the color selection window is designated (Yes in Step A16), the plot point 33g is changed from red to blue (Step A17).

  Then, among the numerical data [X = 96] [Y = 40] of the list data <list 1> <list 2> corresponding to the plot point 33g of the plot graph 32X, “X” <list 1 selected as a reference is selected. Only the color designated in the numerical data [X = 96] is changed from red to blue (step A18).

  Similarly, the color of the designated object can be partially changed while designating the objects (plot points) one by one by operating the cursor key 12i.

  Then, the color of the list data corresponding to the designated object (plot point) is also selected as “X” <List 1>, “Y” <List 2>, or “X & Y” <List 1> < List 2> can be changed.

  On the other hand, in the plot graph display screen 31 according to the display color standard selected in the standard selection menu 24, other standards are displayed in the standard selection menu 24 which is always displayed at the lower end of the display screen 31. When selected (Yes in step A19), the plot graph generation process in FIG. 6 is executed again according to the selected other criteria (step AB).

  When the “EXIT” key 12h provided in the key input unit 12 is operated (Yes in step A20), the graph display state is exited, and the list data corresponding to the graph is read from the list data storage area 15c of the RAM 15. And displayed on the screen (step A21). At this time, if there is a color change in the graph, the color of the displayed list data also changes.

  Therefore, according to the graph display function in the statistical calculation mode in the electronic computer 10 having the above-described configuration, when the user inputs list data, by specifying an arbitrary color for each numerical data of the list data, The scatter plot graph according to the specified color is displayed in color. At this time, when “X” is selected in the reference selection menu 24, each plot point is displayed in color based on the color specified in each numerical data of <List 1>, and when “Y” is selected. Each plot point is displayed in color on the basis of the color designated for each numerical data in <List 2>. Further, when “X & Y” is selected, the plot points where the colors specified in the corresponding numerical data in <List 1> and <List 2> are the same color are displayed in that color and are different colors. However, the plot points are displayed in color in a special manner such as frame-like plot points (33A and 33B). For this reason, it becomes possible to visually grasp the mutual relationship between the list data and the scatter plot graph in terms of color and display mode, and the characteristics of the plot graph drawn based on the list data can be easily understood. become.

  Further, when the user changes the color of the scatter plot graph being displayed in whole or in part, the color change is performed according to the list data (<List 1> or <List 2> or <List 1> selected by the reference). > <List 2>) is reflected in each numerical data, so that the interrelation between the scatter plot graph being displayed and the numerical data in the list data can be easily learned by color change.

  In each of the above-described embodiments, five colors of red (Red), blue (Blue), green (Grn), and yellow (Yllw) are described as examples of colors that can be specified for each numerical data of the list data. However, it may be possible to specify a color other than these colors, or a configuration in which five or more colors can be specified.
