Re: font size problem

Hi Alexander,
I can answer your 2nd and 3rd questions. Someone else will have to
answer as to why you cannot alter the size of the H/L labels.

2) Instead of setting lbOrientation in your mpres list, try setting it
in your opts resource list, as that is where you create your
color-filled plot.

3) What text specifically are you referring to? If you are referring to
the subtitles, then gsnStringFontHeightF in your opts resource list
should work. (I don't believe setting it in the mpres resource will
work.) If you want the latitude/longitude labels to be bigger try
setting mpres@txFontHeightF = 0.03 and see if that changes them.
Otherwise I would try setting mpres@tmXBLabelFontHeightF = 0.020 and
mpres@tmYLLabelFontHeightF = 0.20

Let ncl-talk know if my answers to 2) and 3) don't work out.
Good luck,
Adam
