Sequence Graphing

361

With TIME axes (from Axes on the Y= Editor), you can set

plotstrt = 1

and still graph only

a selected part of the sequence. Simply define a viewing window that shows only the
area of the coordinate plane you want to view.

Changing the Graph Format

The Graph Order format is not available.

•

With TIME or CUSTOM axes, multiple sequences are always plotted simultaneously.

•

With WEB axes, multiple sequences are always plotted sequentially.

Exploring a Graph

As in function graphing, you can explore a graph by using the following tools. Any
displayed coordinates are shown in rectangular or polar form as set in the graph format.

You could set:

•

xmin

= first n value to graph

•

xmax

nmax

(although you can use other

values)

•

ymin

and

ymax

= expected values for the

sequence

Tool

For Sequence Graphs:

Free-Moving
Cursor

Works just as it does for function graphs.
