uTo store graph functions in graph memory

1. Press 4(TOOL)2(GPH-MEM)1(STORE) to display the pop-up window.

2. Press a number key to specify the graph memory where you want to save the graph function, and then press w. Pressing bw stores the graph function to Graph Memory 1 (G-Mem1).

•There are 20 graph memories numbered G-Mem1 to G-Mem20.

•Storing a function in a memory area that already contains a function replaces the existing function with the new one.

•If the data exceeds the calculator’s remaining memory capacity, an error occurs.

uTo recall a graph function

1.Press 4(TOOL)2(GPH-MEM)2(RECALL) to display the pop-up window.

2.Press a number key to specify the graph memory for the function you want to recall, and then press w. Pressing bw recalls the graph function in Graph Memory 1 (G-Mem1).

•Recalling data from graph memory causes any data currently on the graph relation list to be deleted.

4.Saving and Recalling Graph Screen Contents

You can save the contents of the graph screen to a file. The format of the file is g3p, which is a proprietary format unique to this calculator. Performing the save operation in this section saves the following information.

•A bitmap image of the graph

•A bitmap image of the graph background (including axes, grid, axes labels, background image)

-The background image includes the lightness setting, so it is saved as it appears on the graph screen.

-The function menu and status are not included in the background image.

•V-Window settings (excluding Tmin, Tmax, Tptch values)

Saved images can be recalled to a graph screen and overlaid onto another graph, or recalled from and used in another application.
