Thank you for your comments. After some hunting, I stumbled on the option
that allows one to appoint a group variable. For those others who may not
be aware of this,
1) right click on the group column
2) you will be presented with several options. Select "group"
3) Select the variables to be plotted
4) select scatter plot under analyze
Insight appears to be somewhat inconsistant in offering options since the
aforementioned method is offered but some analysis tools but in at least
one other case, that of XY fit, a window appears that allows one to make
several choices about the analysis including selecting a group variable.
Thanks again for the tip.

Please respond to
I clearly did not understand this one.
When I checked scatter plots in INSIGHT (version 8.2)
there is a GROUP box in the options and if you put a
varable in there you get a scatter plot for each distinct
of that variable.
PS the new robust/resitant regression routines in IML are
excellent for this type of screening as they can detect
