Perform the mode specification operation in step 4. Next, as shown in step A5, input the graph data by operating the DT key 18, and then specify the graph shown in step A6Vc.
The details of the graph designation button 6 will be explained below.

In the above-mentioned Stella fA5, the graph data input by operating the DT key 18 is written to the SD memory 31 and I, R memory 32 in the storage unit 24 through a predetermined process (details will be described later). . Now, for example, in Figure 4 (a

In this step B4, if it is determined that the above conditions are not satisfied, the process is directly terminated, but if the above conditions are satisfied b, the process proceeds to step B5 and the condition of X≧Xm1n is satisfied. Decide whether or not. In this step B5, if it is determined that the above conditions are not satisfied, the process is immediately terminated, but if it is determined that the above conditions are satisfied, the process proceeds to step B6.

That is, the Stella fB41. B5 input, input r-

The contents of 1 are incremented by "+1" and the processing for the input data is ended. Thereafter, the above operation is repeated every time the DT key 18 is operated, and the distribution state of the input data is written in the SD memory 31.

Furthermore, if it is determined in step B1 that the SD mode is not specified, the process proceeds to step B8, and L
By operating the R key 11, it is determined whether the 9LR mode is designated. If the LR mode is not specified, the process ends, but if the LR mode is specified, the process proceeds to step B9, and the two numerical data held in the formula buffer 22 are stored in the t-X memory 34 and the Y memory. 35 respectively. Then proceed to step BIO,
The content X written in the X memory 34 is Xm1n≦X<Xrl

It is determined whether or not the condition is satisfied, and if the condition is not satisfied, the process is immediately terminated. That is, the above step Bxo,
BIIIC determines whether the input data is within a range that can be graphed, and if graphing is possible, the process advances from step Bll to step BJj. This step B12
Now, the data held in the X memory 34 is written to the X area of the LR memory 32, the corresponding data held in the Y memory 35 is written to the Y area of the LR memory 32, and the process is completed.

A graph corresponding to the specified contents is created by the above-mentioned graph designation operation, and its details will be explained below using 70-Chart 70 in FIG. 6. That is, when the execution key 19 is operated, the control unit 20 determines whether or not the SD and LR graph modes have been designated, as shown in step C1 in FIG. , and proceeds to step 02IC to execute other processing. If SDt or I,R mode is specified, the process advances from step C1 to step C3 and the formula buffer 22t is
A formula judgment command for IC is output, and first, step C4
It is determined whether Graph designation is performed in .

If Graph specification is not done, the above Stella f
The process of C2 is executed, but for a designated table with Graph designation, the process proceeds to step C5, where it is determined whether or not Lin designation has been performed. If the line is specified (with Line designation), the process advances to step C6Vc, and bar graphing processing, which will be described in detail later, is executed. If there is no Line designation, the process advances to step C7, where it is determined whether or not the SD odd mode is designated, and the SD
If the odd mode is not specified (b), the process proceeds to step C8, and LR line graphing processing, which will be described in detail later, is executed.

In addition, in step CF, if it is determined that there is no SD odd mode, proceed to Stellar fC9, determine whether Lin・1 is specified, and if L1n@1 is not specified, proceed to step CIO to check the details. 8D line graphing processing, which will be described later, is executed. Further, if it is determined in step C9 that Line is specified, the process proceeds to step C1l and normal distribution graphing processing is executed.
