ZOOM operations in Seq graphing work the same as in
Func graphing. Only the X (Xmin, Xmax, and Xscl) and Y
(Ymin, Ymax, and Yscl) window variables are affected.
PlotStart, PlotStep,
n
Min, and
n
Max are only affected when
you select ZStandard. The VARS Zoom secondary menu ZU
items 1 through 7 are the ZOOM MEMORY variables for Seq
graphing.
The only CALC operation available in Seq graphing is value.
• When Time axes format is selected, value displays Y (the
u(
n
) value) for a specified
n
value.
• When Web axes format is selected, value draws the web
and displays Y (the u(
n
) value) for a specified
n
value.
• When uv, vw, or uw axes format is selected, value
displays X and Y according to the axes format setting.
For example, for uv axes format, X represents u(
n
) and
Y represents v(
n
).
To enter the sequence names u, v, or w, press y [u], [v], or
[w]. You can evaluate these names in any of three ways.
• Calculate the
n
th value in a sequence.
• Calculate a list of values in a sequence.
• Generate a sequence with u(nstart,nstop[,nstep]). nstep
is optional; default is 1.
