Graph Memory
Graph memory lets you store up to 20 sets of graph function data and recall it later when you
need it.
A single save operation saves the following data in graph memory.
• All graph functions in the currently displayed Graph relation list (up to 20)
• Graph types
• Function graph line information
• Draw/non-draw status
• V-Window settings (1 set)
S
To store graph functions in graph memory
1. Press (GMEM) (STO) 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 U . Pressing @ U 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.
S
To recall a graph function
1. Press (GMEM) (RCL) 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
U
. Pressing
@ U
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. Storing a Graph in Picture Memory
You can save up to 20 graphic images in picture memory for later recall. You can overdraw
the graph on the screen with another graph stored in picture memory.
S
To store a graph in picture memory
1. After graphing in GRAPH mode, press
*
(PICT) (STO) to display the pop-up
window.
2. Press a number key to specify the Picture memory where you want to save the picture, and
then press U . Pressing @ U stores the picture function to Picture Memory 1 (Pict 1).
• There are 20 picture memories numbered Pict 1 to Pict 20.
• Storing a graphic image in a memory area that already contains a graphic image replaces
the existing graphic image with the new one.
• A dual graph screen or any other type of graph that uses a split screen cannot be saved in
picture memory.
