Hi there,
I got this code which plot what i want but doesn't put the colorbar
outside of the plot as it used to... Any Ideas?
nlevels = 20
levels = -100+indgen(20)*10
pos = [0.1, 0.1, 0.9, 0.75]
LoadCT, 33, NColors=nlevels, Bottom=1
lonW=0 & lonE=360 & latS=-20 & latN=90 &
limitplot=[latS,lonW,latN,lonE]
map_set,/orthographic,34.5,-117.7,limit=limitplot
PS_start,filename='testpv.ps',/nomatch,charsize=0.8
cgcontour, pv,lon,lat, NLevels=nlevels,levels=levels, /
cell_Fill,C_Colors=Indgen(nlevels)
+1,xrange=[-180,179],xstyle=1,Position=pos,charsize=1,/close d,/
overplot
map_continents & map_grid
cgcolorbar, RANGE=[-100,100],NColors=nlevels, Bottom=1,
Format='(F0.1)',Divisions=nlevels/2, XMinor=0
Ps_end,/png
Thanks
Cheers

Ah, well, I just looked for it in the IDL 7.0 on-line help.
It's there, but you are right, it is NOT prominently
displayed. (It is under the Graphics Keywords section.)
But, yes, you should look in my books first. Most of what
I ever need to know is in one or the other of those
books! Or, if not there, in an article on my web page. ;-)
Cheers,
David

My bet, there is a position keyword in map_set which is not detailed
in IDL help but use in your book... I should have known now where to
look first !!!
Thank you

Well, you just named three possibilities for doing so.
Have you tried any of them? :-)
Here is a suggestion. Stop doing all your plotting in
PostScript. Draw your plots on the display where you
can see what is happening, and try stepping through
your code one command at at time. It might be
illuminating. When you understand what your code
does, *then* send it to a PostScript file.
Cheers,
David

Yes the problem come from overplot and i don't understand well the
map_projection, continents and grid...
I just want to have some space above the drawing to put the colorbar.
Thanks

Oh, never mind. I just looked at your code again. It
is not cgContour that is creating the plot space.
cgContour is just drawing contours on a plot space
that already exists. So you are right, the POSITION
keyword is doing nothing, as it should when the OVERPLOT
keyword is set.
What command should you set the POSITION keyword on to
make it do some good in your program?
Cheers,
David

Humm. Do you know for a fact that these values are being
passed to cgContour? How would you test that? How would
cgContour act if it never saw these values?
Cheers,
David

when i change a value in pos (which i use in position in cgcontour).
I started with pos = [0.1, 0.1, 0.9, 0.75] and change it in pos =
[0.1, 0.1, 0.4, 0.75] but it doesn't change anything on the plot
