There are many options available from the main menu of PLOT
as well as options after the graph has been displayed. For example,
you can plot a function of your data that satisfies certain
conditions, do a least squares fit to that data and then graph the
residuals. Here is the complete main PLOT submenu:
\* Options are:
1) Y < IP >
2) X < NE >
3) Constraints < >
4) Symbols < >
5) Graph ranges <Y: 0.0, 0.0, LIN> <X: 0.0, 0.0, LIN>
6) G+ Graph Plus <Auto-scale_Y:min=T,max=T><Auto-scale_X:min=T,max=T>
7) Key for dynamic cursor option <SHOT>
8) Join <off>
9) Multiple Ys: <off>
10) Analysis: Average, Frequency, Error, Integral/deriv, FIt symbols
11) Output: Type, Stats, Journal, Device, VGDS, Close plot file, ...
12) Extras: Text, Curve, Grid, High Resolution, Color
When you have set all the items to describe the set of data you want,
enter ; to retrieve and graph the data. After the graph has
been drawn, you can choose from a number of after-graph options which
are described in Section 2.6.
