I'm grateful you have given up looking for "easy" solutions. ;-)
Yes, it is possible, but you have to futz around a bit.
Here is an article:

Thanks David,
If I may ask one follow up question on plotting:
Is it possible to choose which values are displayed on a given axis?
Let me elaborate with an example... I am doing a 'plot_io' (y
logarithmic) with 'yrange=[50,3500]' and 'ystyle=1' (to overide the
IDL default range). IDL labels the y-axis at y=100 and y=1000. Is
there a way to ask IDL to also put labels at y=50 and y=3000 without
adding them by hand (xyouts)?
I appreciate the help!
Will

Use XThick, YThick, etc. Or, !X.Thick, !Y.Thick, etc.

Oh, well, then use PS_Start. All this is then done automatically. ;-)

It depends on whether you can find these characters in a font-set
somewhere. If you can, it is fairly easy. If you can't, then
it is not so easy.
