There are several options available after the graph is drawn which are
summarized in the following table. You will be prompted with the bell
when a response is expected. You will stay in *graph mode* until
you enter a `RETURN` or `SPACE` to return to the main menu of
PLOT.

After the graph īs drawn, enter:

RETURN to return to the plot menu (or SPACE).

? for this help.

C click to select value, click to display value, end with ;.

L to display the legend (constraints, fit equation, ...).

P to page before showing the legend.

S to show the mean, min, max, etc. of parameters previously

selected with the PLot Output Stats option.

W to replot just the graph without the legend (includes fit).

If logical name

plotincludes a file, e.g. ``tescal.plt,'' enter:D to send this page to the file.

To get a fit to the data, enter:

0 for a proportional fit.

1 or F for a straight line fit.

2 - 9 for a polynomial fit.

N for a nonlinear fit or an arbitrary function of x.

Before a fit, enter:

A for the ANOVA table of statistics for the next linear fit.

* to suppress IMSL error messages until you return

to the plot menu.

After the fit line is drawn, enter:

R for a plot of the residuals.

Q for a plot of the ratio of the fit to

y.E type the equation of the fit on the alpha screen for ``mousing''.

After a frequency graph has been drawn, enter:

M for the mean and median.

G for the standard deviation and a Gaussian fit

to the distribution.

When using the cursor option, enter:

; to end the list of points being selected.

The legend is all the text except for the axis labels. You can use
the `W` option to replot just the graph if you want to make
``hardcopies'' without the legend or if you want to see the data
uncluttered. The graph includes the fit curve, but not the equation
of the fit.
