Hi Teddy,

You should be able to export to a transparent PNG:

p=PLOT(leeTRMMday,
color='magenta',yrange=[0,0.5],thick=2,xticks=12,xtickname = months,$
title='1998 - 2009 TRMM daily climatology')
p.Save, 'myplot.png', /TRANSPARENT

There are other keywords to the Save method which might be useful,
like BORDER, RESOLUTION, WIDTH, HEIGHT, etc.

Cheers,
Chris
