2. Description of the Related Art Some conventional character processing devices are also configured to output numerical data as a graph when the numerical data is input to the device.

[0003]

However, the above-mentioned device has various restrictions on the format of data for graphing, the input method, the output form, and the like. In particular, when two-dimensional matrix data in a matrix format is graphed, for example, when a bar graph in which a bar is extended in the horizontal direction is created, there are two types of data depending on which of the row and column data is the vertical axis. Although different graph representations of can be considered, conventionally, only one graph representation can be fixedly implemented for one table, and in order to obtain a desired graph representation, the rows and columns of the table are matched to the representation. It had to be created in a different format, and the flexibility of input operations and graph representation was low.

[0004]

In order to solve the above problems, the graph creating method of the present invention stores an input step of inputting a character / numeric string and a character / numeric string input by the input step. Storing step, a display step for displaying the character / number string stored by the storing step, and a character / number string displayed by the display step by specifying a rectangular area on the display with a cursor. A graphing target designating step of designating a matrix-type numeric string group in the rectangular area as a graphing target from among, and a numerical value group represented by the matrix format numeric string group designated by the graphing target designating step. The step of instructing to create a graph of, the step of generating a graph pattern corresponding to the size of each numerical value of the numerical value group, and the row or column of the numerical value group of the matrix form data A selection step of selecting the other as a set of data of the same item, a position specification step of specifying a graph output position using a cursor on the display, and an instruction of the instruction step to select the selection step. Based on
Using the graph pattern generated by the generation step, the time point is set in the axial direction orthogonal to the direction in which the graph pattern increases or decreases according to the size of the numerical value, and the time point is the same point for the data of each item. And a graph creating step of creating a graph for outputting the graph pattern at the position at the time point and outputting the graph at the position specified by the position specifying step.

[0005]

With this structure, a character / number string is input in the input step, stored in the storage step, displayed in the display step, and in the graphing target specifying step, a rectangular area is specified on the display by using the cursor. By doing so, from the displayed character / number sequence, the matrix-type number sequence group in the rectangular area is designated as a target for graphing, and an instruction is made to create a graph of the number group represented by the matrix-type number sequence group. Instructed by the process, select one of the rows and columns of the numerical value group in the matrix form as the data set of the simultaneous points and the other as the data set of the same item in the selection process, and select it on the display in the position specification process By specifying the output position of the graph with the cursor, the graph pattern corresponding to the size of each numerical value of the numerical value group is generated in the generating step, and the generating pattern is generated based on the selection. Using the graph pattern generated in, the time point is taken in the axial direction orthogonal to the direction in which the graph pattern increases or decreases according to the size of the numerical value, and the time point is the graph pattern for the data of each item at the same time. A graph to be output to the position at that time is created and output to the position specified in the position specifying step.

As shown in FIG. 4A, the graph pattern code strings are α, β, β, γ from the third line of the graph font table GF.
Therefore, this code string is written in the buffer BUF. The write position to the buffer BUF is indicated by the value of the cursor register CR, and the pattern code string corresponding to the first row of the graph table memory GT is sequentially transposed starting from the position indicated by the cursor register CR. Write in the direction (to the right on the same line). The pattern code string corresponding to the second row of the graph table memory GT is written in the row next to the position in the buffer indicated by the cursor register CR.

Writing is sequentially executed in the following order.

Further, in the present embodiment, the range is defined by the two keys, the range start key and the range end key, but these keys are combined into one key, for example, the key operation is stored in the RAM, and the odd number is stored. The beginning of the range may be designated for the keystroke of the even number, and the end of the range may be designated for the keystroke of the even number. Also, the key operation information is read out from the RAM,
The lamp may be turned on at odd-numbered keystrokes and turned off at even-numbered keystrokes.

Furthermore, in the present embodiment, it has been described that only the graph is displayed on the CRT, but it is also possible to simultaneously display the scale or the frame.

Although only the input procedure has been described in the present embodiment, various peripheral devices such as a printer and a disk may be provided in the character processing device of the present invention.

Although the number of data items is 2 in this embodiment, it is of course possible to display a graph by the same processing even if the number of data items is 3 or more. In this example, only the horizontal bar graph is displayed for output, but it goes without saying that a vertical graph display or a line graph display may be used instead.

[0068]
