Trouble-shooting a plot
If you have problems plotting, check that you have the
following:
• The correct fit (regression model).
• Only the data sets to compute or plot are
checkmarked (Symbolic view).
• The correct plotting range. Try usingVAuto Scale
(instead of
P
), or adjust the plotting parameters
(in Plot Setup) for the ranges of the axes.
• Ensure that both paired columns contain data, and
that they are the same length.
• Ensure that a paired column of frequency values is
the same length as the data column to which it refers.
Exploring the graph The Plot view has menu keys for zooming, tracing, and
coordinate display. There are also scaling options under
V.
