Hello,
I want to plot a 2D histogram with tvim with a black and white color
table.
I want the pixels with no data to be plotted in white and pixels with
the most data in black.
To do so, i type:
loadct,0
reverse_ct
tvim,map,/scale,nodata=0.0....
It plots my pixels with the wanted colors but the axis, labels and
titles have disappeared (have been plotted in white i guess).
How to force tvim to plot the axis, titles in black but use the color
table I want for the plot ?
If someone has an idea! :=)
Thanks!

Changes are coming later today that I think will make
TVImage even more attractive to astronomers. Check
the newsgroup later for an announcement. :-)
Cheers,
David

Use TVIMAGE. ;-) (yeah, tvim does some useful stuff automatically,
but when it comes to dealing with colours, TVIMAGE is more robust)
