Re: conset problem??

[Mick Spillane <spillane@xxxxxxxxxxxxx>]

Hello Min,
	The ppl commands modify the characteristics of a plot (or a plot
overlay) BEFORE it is drawn. In general it does not change the look of
a plot already drawn.  So to alter the height of the contour labels in
your example you could proceed as follows

shade/i=1:10/j=1:10 i+j          ! make the color plot
contour/o/set/i=1:10/j=1:10 i+j  ! set up, but don't draw contour lines
ppl conset,0.2                   ! define the height of contour labels
ppl contour/over                 ! draw the contour lines

Good luck,
Mick

PS here is why your example#2 did not work
