Trouble-shooting a plot
If you have problems plotting, check that you have the
following:
• The correct 9$5_ or 9$5_ 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 >9,(:6@ Auto
Scale (instead of >3/27@), or adjust the plotting
parameters (in Plot Setup) for the ranges of the axes and
the width of histogram bars (HWIDTH).
•In 9$5_ mode, ensure that both paired columns contain
data, and that they are the same length.
•In 9$5_ mode, ensure that a paired column of frequency
values is the same length as the data column that it refers
to.
