Controlling What Appears On A Graph Screen - Casio fx-9750GII User Manual

Repeat this step as many times as required to input all of the functions you want.
Next you should specify which of the functions among those that are stored in memory
you want to graph (see page 5-6). If you do not select specific functions here, the graph
operation will draw graphs of all the functions currently stored in memory.
3. Draw the graph.
• You can use the function menu that appears when you press
above procedure to select one of the following line styles for each graph.
( ) ... Normal (initial default)
( ) ... Thick (twice the thickness of Normal)
