Hej!
This object oriented graphics driving me mad. Why is it so hard to get
good looking graphics in IDL with a little bit of simple functionality
like zoom, ...? Why do I need ten lines of code to place a simple text
on a plot? ... I am used to Matlab that has a very simple syntax to
make plots, legends, annotations, ... but has a powerfull interface
like iPlot to zoom, change or annotate the plots.
But enough complaining I have to work and to live with IDL. I hope you
can help me. My question:
I use iPlot to plot my data and ixyouts (D. Fanning) to annotate the
Plot. The axis fonts (xtickfont=10.0, ytickfont=10.0) and the fonts in
ixyouts are set to 10 pt. How do I get "access" to the Legend to
change the font also there? How can I apply the following object to my
legend?
helvetica10pt = OBJ_NEW('IDLgrFont', 'Helvetica', SIZE = 10)
It would be great if you could give me a hint and to ease my pain ;)
Kind regards,
Christian
