Editing Tables and Drawing Graphs
u u u u u To specify the color of the graph ({BLUE}/{ORNG}/{GRN})
CFX
The default color for a graph is blue. Use the following procedure to change the
graph color to orange or green.
1. Display the Recursion Menu and then use f and c to highlight the formula
2. Press 1 (SEL+C).
3. Press the function key that corresponds to the color you want to specify.
u u u u u To specify the draw/non-draw status of a formula ({SEL})
There are two options for the draw/non-draw status of a recursion formula graph.
P.222
To specify the draw/non-draw status, use same procedure as that for specifying
generation/non-generation status.
u u u u u To specify the type of data to be plotted (Σ Display: On)
You can specify one of two types of data for plotting.
In the function menu that appears while a table is on the display, press 5
(G·CON) or 6 (G·PLT) to display the plot data menu.
