Trouble-shooting a plot
If you have problems plotting, check that you have the
following:
• The correct or menu label on (Numeric
view).
• The correct fit (regression model), if the data set is two-
variable.
• Only the data sets to compute or plot are checkmarked
(Symbolic view).
• The correct plotting range. Try using |
views
| Auto
Scale (instead of rPLoT|), or adjust the plotting
parameters (in Plot Setup) for the ranges of the axes and
the width of histogram bars
(HWIDTH).
• In WitfCl mode, ensure that both paired columns contain
data, and that they are the same length.
• In mode, ensure that a paired column of frequency
values is the same length as the data column that it refers
to.
