Dear IDL users,
I'm trying to create an Angstrom symbol (using CGSYMBOL) within the PS environment (using PS_START and PS_END). However, the output is not showing the correct Angstrom symbol: the small circle above it is missing.
When I call PS_END with the /PNG option, I can see in the PNG file that everything's OK with the symbol.
Here is the piece of the code where I want the Angstrom symbol to appear:
+++++++++++++++++++++++++
ps_start, filename=nameout[0]+'.ps', /quiet, /nomatch
[LOTS OF COMMANDS]
setdecomposedstate, 1, currentstate=mode
[CGPLOT, CGPLOTS, etc.]
setdecomposedstate, mode
cgcolorbar, range=alog10([minvalue,maxvalue]),$
position=[0.764567+0.01,0.13,0.764567+0.03,0.925709],$
yminor=1, charsize=0.9, format='(F0.1)',$
title='Residual flux (erg s$\up-1$ cm$\up-2$ $\angstrom$$\up-1$)',$
/vertical, /right
ps_end, /png
+++++++++++++++++++++++++
Anyone have any idea of what's happening?
Thanks in advance.
m.

You look like you are using a large character size, so I suppose it is
possible you are writing outside of the graphics "window". Have you
tried moving the left-hand edge of your plot over a little to give
yourself more room for the axis annotation?
Cheers,
David

I think it is more likely that this particular hardware font doesn't
support the Angstrom sign properly. Fonts are notorious for not being in
compliance with standards. True-type fonts are better in this regard
because they are usually more "modern."
I find it hard to believe, however, that you can't find a true-type font
to match the font in your paper. What kind of font are you using?
In any case, when device independence became my goal, I switched from
hardware to true-type fonts and never looked back.
There is no way to set the text "window size" as far as I know. And I
doubt very much it would help in this situation anyway.
Cheers,
David
