k Using Graph Functions in a Program
You can incorporate graph functions into a program to draw complex graphs and to overlay
graphs on top of each other. The following shows various types of syntax you need to use
when programming with graph functions.
• V-Window View Window –5, 5, 1, –5, 5, 1_
• Graph function input Y = Type_ ....................Specifies graph type.
"X
2
– 3" → Y1*
1
_
• Graph Color SetG-Color Green, 1_
• Graph draw operation DrawGraph
*
1
Input this Y1 with J4(GRAPH) 1(Y) b (displayed as ). A Syntax ERROR will
occur if you input “Y” with the calculator keys.
