When the cursor Cu is selectively moved to the position of the statistical mode icon [STAT (2)] according to the operation and the “EXE” key 12f is operated, the mode data of the statistical mode is set in the mode data memory 19b and the statistical data is set. Mode processing is started (step S1) [first layer].

  Then, as shown in FIG. 7B, a list screen G1 for inputting statistical data is displayed. In accordance with this data input list screen G1, any statistical data (List1 [JIKAN] / List2 [KYORI]) to be calculated and analyzed is input by moving the cursor Cu using the cursor keys 12g and inputting the numerical keys 12a. Then, the inputted statistical data (List1 / List2) is sequentially stored in the work area 19h via the key input memory 19c (step S2) [second layer].

  When the “EXE” key 12f is operated after the statistical data is input, a statistical graph condition setting screen G2 for graphing and analyzing the statistical data is displayed as shown in FIG. 7C. In the statistical graph condition setting screen G2, based on the operation of the function key “F1” corresponding to the [LIST] button, the data of (List1 / List2) as each analysis target of the X axis (XList) / Y axis (YList) Is selected and set (step S3), and, as shown in FIG. 7D, a data plot is displayed as the graph data display format (Graph Type) based on the operation of the function key “F1” corresponding to the [Scat] button. (Scatter) is set, and similarly, “□” is set as the display format (Mark Type) of the data plot (step S4) [third layer].

  When the “EXE” key 12f is operated after selecting the analysis target and setting the display format, the statistical data (List1 / List2) selected and set as the analysis target is displayed in accordance with the display format setting conditions shown in FIG.

(Step S9) [fifth hierarchy] .

  FIG. 9 is a flowchart showing an operation procedure storing process started in parallel with the statistical analysis process of the graph scientific calculator 10.

  In this operation procedure storing process, as shown in FIG. 4, a recording process to the work procedure / change setting data memory 19g is performed for each key operation input in the statistical analysis process in FIGS. Steps A1 to A6 → A1).

  That is, when processing corresponding to the key operation input is executed (step A1), the key operation data is first recorded (step A2). Then, the work order and work items recognized in accordance with the execution of the process associated with the key operation input, and each data of the process hierarchy are recorded (step A3 → A4).

  Further, for each work item, the status data of the process is recognized as belonging to (1) input process, (2) setting process, or (3) output process, and can be changed as status data (possible) (No ) Are recorded (step A5).

  As a result, when the above-described statistical analysis process of the work procedure is performed, as shown in FIG. 4, the work procedure / change setting data in which operation data, work order / work item, hierarchy, and state data are recorded. A memory 19g is generated.

  FIG. 10 is a flowchart showing a re-execution process performed based on the work procedure / change setting data memory 19g generated according to the operation procedure storage process of the graph scientific calculator 10.

  When the re-execution process in FIG. 10 is started in order to similarly analyze the statistical analysis process performed in response to the user operation by changing some of the input data and setting data, the work procedure / change is performed. The list data stored in the setting data memory 19g is read as it is and displayed as shown in FIG. 4 (step B1). At this time, the items of “work selection” and “re-execution setting” in the displayed work procedure / change setting data (19g) are blank because they are not set.

  In the display state of the work procedure / change setting data (19g), for example, when it is desired to change and reanalyze the input contents of statistical data, the “work selection” corresponding to the work item “2. The item field is selected with the cursor 12g and the "EXE" key 12f is operated and input, the change setting flag is stored, and the work to be changed is set (step B2).

  In addition, when the re-execution processing is performed, if the user wishes to stop or end the processing of the desired work item, the “Re-execution setting” item field corresponding to the work item “4. The cursor 12g is used to select and store “stop” and set the work position to be stopped. Further, for example, the item field of “re-execution setting” corresponding to the work item “7. data regression” to be finished is selected by the cursor 12g, and “end” is input and stored, and the work position to be finished is set ( Step B3).

  In this way, based on the list display of the work procedure / change setting data (19g), the work to be changed is set, and the re-execution is instructed by the user operation in the state where the work positions to be stopped and finished are set. Then (step B4), the operation data recorded in the work procedure / change setting data (19g) is sequentially read from the head according to the work procedure (step B5), and the same statistical analysis according to the operation data is performed. Processing is automatically re-executed sequentially (steps B6 to B9).

  At this time, each time the operation data recorded in the work procedure / change setting data (19g) is sequentially read according to the work procedure (step B5), the “work selection” item column corresponding to the work procedure is displayed. It is determined whether or not the change setting flag is set (step B6), and it is determined whether or not “stop” is set in the “re-execution setting” item field corresponding to the work procedure (step B6). B7).

  Here, when the operation data corresponding to the work procedure “2. Data input” recorded in the work procedure / change setting data (19g) is read (step B5), the “work selection” corresponding to the work procedure. When it is determined that the change setting flag is set in the item field (step B6 (YES)), the data input list screen G1 shown in FIG. 7B is displayed again, and the list screen G1 is displayed. The statistical data at the time of the previous statistical analysis that has already been input and displayed in the state is accepted (step B61).

  When the statistical data at the previous statistical analysis is changed and input on the data input list screen G1 and the “EXE” key 12f is operated, the operation procedure “2. Data input” in the operation procedure / change setting data (19g) is performed. The statistical data associated with the previous statistical analysis stored as the operation data associated with is rewritten with the statistical data after the change (step B62). Then, the operation data of the next work procedure is sequentially read out based on the statistical data after the change, and the statistical analysis processing corresponding to the work procedure “3. Analysis content setting” as in the previous time is continuously executed automatically. (Step B9).

  Thereafter, when the operation data corresponding to the work procedure “4. Graph drawing” recorded in the work procedure / change setting data (19g) is read (step B5), the “re-execution setting” corresponding to the work procedure is read. When it is determined that “stop” is set in the item field (step B7 (YES)), processing according to the work procedure “4. graph drawing” is executed, and the changed A graph analysis screen G3 (see FIG. 7E) on which data plots P1, P2,... Corresponding to the statistical data are drawn is displayed (step B71). Then, the operation is stopped in a state where the graph analysis screen G3 of the data plots P1, P2,... After the change is displayed (step B72).

  When the “EXE” key 12f is operated and input in the operation stop state in the user-desired work procedure “4. graph drawing” (step B73 (Yes)), the operation stop is canceled and the next work procedure is performed. And the statistical analysis process corresponding to the same work procedure “5. Drawing of prediction graph”, “6. Regression condition setting”, etc. is resumed and automatically executed again (step B9).

  Therefore, according to the operation procedure storage / change / re-execution function of the graph scientific calculator 10 having the above-described configuration, for example, when performing statistical analysis processing based on desired statistical data, key operation data input in response to a user operation Are sequentially recorded, the work order and work items of the processing unit executed in accordance with the key operation data are recognized, and the work procedure / work item / list of work orders / work items associated with the key operation data are listed. Recorded as change setting data (19g). Thereafter, a list of work orders and work items associated with user operations recorded as the work procedure / change setting data (19g) is displayed as a list, and a work item for which input data or setting data is to be changed is designated and processed. Is re-executed, the same statistical analysis process is automatically executed based on the key operation data recorded in the work procedure / change setting data (19g), and when the designated work item is processed, The input data or setting data change is accepted, and it is possible to easily change to the desired input or setting data and perform the same statistical analysis process repeatedly. For this reason, when performing the same calculation process repeatedly by changing the conditions without the need to find and change the input change or setting change while confirming the execution of a series of pre-recorded processes one by one for each process again. The work efficiency can be greatly reduced and the work efficiency can be improved.

  Further, according to the operation procedure storage / change / re-execution function of the graph scientific calculator 10 having the above configuration, a list of work orders and work items associated with user operations recorded as the work procedure / change setting data (19g) is displayed. When a work item to be stopped or terminated is designated and the process is re-executed, the same statistical analysis process is automatically performed based on the key operation data recorded in the work procedure / change setting data (19g). At the same time as the processing of the work item designated to be stopped or terminated halfway, the processing is stopped or terminated in a state where the processing is performed. For this reason, it is not necessary to repeatedly execute a series of pre-recorded processes, and the processing result of the user-desired work item can be easily stopped and checked while changing the conditions of the input data and setting data. In addition, it is possible to easily end the repeated processing at the processing of the work item desired by the user, and the work efficiency can be further improved.
