PURPOSE:To easily display a part where data are desired to be inputted, and to prepare a graph by a desired procedure by cyclically switching plural screens for operating the input of the data and the output of the graph by one key. CONSTITUTION:A graph preparation main control 14 switches a screen displayed at a display 12 by a screen switching control 15, and selects and executes a processing (format setting control 16, constitution item control 17, and graph screen control 18) corresponding to each screen. At that time, the data which are not inputted at all are processed by a default value. For example, when a format setting screen is displayed, the screen is changed to a graph display screen by pressing 'the next page' key. Then, the screen is changed to a constitution item screen by pressing 'the next page' key. Moreover, the screen is changed to the format setting screen again by pressing 'the next page' key. And also, when 'a previous page' key is pressed, the screen is switched by a screen transition reverse to that of 'the next page' key. |
