plotting tables with sgraphStarted by:kkwitter, 06/09/2006 08:28PM
I am having trouble with the syntax for
plotting 2 column sof a 4-column table
with sgraph. I want to plot column 2 on
the x-axis and 3 on the y axis, but
several attempts with various suggested
and implied formats have been
unsuccessful.

Thanks!
