User Generated Graphs
Built-in function graphs can aiso be used in combination with each other. Graph-
ing a formula such as.y = 2 x
2
+ 3 ;t- 5 makes it possible to visually represent the
solution.
Unlike built-in functions, the ranges of user generated graphs are not set auto­
matically, so graphs produced outside of the display range do not appear on the
display.
■Range parameters
After pressing the S key, you can look up and specify the range parameters
for the
x - and y - coordinates. Range parameters consist of maximum and mini­
mum values for each axis, as well as their scales (distance between hash marks).
Before drawing a graph, you should first specify range parameters to set the size
of the graph.
•Range parameter types
Range parameters consist of the following:
Xmin — minimum value of the x-axis
Xmax — maximum value of the x-axis
OCscI — scale of the *-axis
Ymin — minimum value of the .y-axis
Ymax — maximum value of the .y-axis
Yscl — scale of the .y-axis
•Specifying range parameters
Whenever you press the S key (except in the BASE-N mode), the range parameter
setting screen appears on the display. Enter the value you want to specify for the
displayed parameter and then press (iD.
