Dear David,
It is working perfect now. Here I have few queries:
1. To match color of zero level in contour to that with colour bar, I used following commands for my plot and it is working. But colours shift in blue direction in one step.I tried with 'bottom'=2 or =1 in both cases for colourbar and table, but it is not matching together.
nl=13
level=(findgen(nl)*.5-3)
colour=(findgen(nl+1))
cgerase
cgLoadCT, 24, NColors=14, Bottom=2, /Brewer,/reverse
cgColorBar,NColors=14, bottom=1, Division=14
2. Can I simply make white on both sides of zero contour?
3. The colour you specified are really nice. But can I change those colours a bit, say for both blue or red can they be little lighter? or say can they be purple and orange?
Thanks and regards,
