Hi,
It's been quite a while since I've programmed in IDL but I have a
problem with something very basic. I am drawing a grid using the PLOTS
command but the final lines are not being drawn (i.e. the top and
rightmost lines). I might use a hack to get it to look right (i.e.
enlarge the window by a few pixels) but it's not a very elegant
solution. Below I list a simple procedure that shows the issue. You
should see a window pop up with most of the grid except for lines
along the top and along the right. Any help on my pedestrian
problem? :o)
Thanks,
Rob
