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 plot includes 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.
