Selecting Axes Combinations
Setting the Graph Format
To display the current graph format settings, press y.. Chapter 3 describes the format settings
in detail. The other graphing modes share these format settings. The axes setting on the top line of the
screen is available only in Seq mode.
Setting Axes Format
For sequence graphing, you can select from five axes formats. The table below shows the values that
are plotted on the x-axis and y-axis for each axes setting.
Displaying a Sequence Graph
To plot the selected sequence functions, press s. As a graph is plotted, the TI-84 Plus C updates X,
Y, a n d
n.
Smart Graph applies to sequence graphs (Chapter 3).
Exploring Sequence Graphs
Free-Moving Cursor
The free-moving cursor in Seq graphing works the same as in Func graphing. In RectGC format, moving
the cursor updates the values of X and Y; if
CoordOn format is selected, X and Y are displayed. In
PolarGC format, X, Y, R, and q are updated; if CoordOn format is selected, R and q are displayed.
TRACE
The axes format setting affects TRACE.
When
Time, uv, vw, or uw axes format is selected, TRACE moves the cursor along the sequence one
PlotStep increment at a time. To move five plotted points at once, press y~ or y|.
• When you begin a trace, the trace cursor is on the first selected sequence at the term number
specified by
PlotStart, even if it is outside the viewing window.
