#You can also perform trace, etc. for drawn function graphs.

#Graphs of types other than rectangular coordinate graphs cannot be drawn.

#Pressing J while inputting a function returns the expression to what it was prior to input. Pressing !J(QUIT) clears the input expression and returns to the statistical data list.
