[yt-users] Fonts size in the Projection plot.

[Jun-Hwan Choi]

Dear Nathan,

Thank you for you help.
However, when I try to follow your suggestion, yt complains that
>> slc.set_font(font_dict)
>> AttributeError: 'ProjectionPlot' object has no attribute 'set_font'
Meanwhile, I try your approach only for annotate_text then it works.
So, now I can control the text size but I still can not find how increase x
y label and tick size.
Is there other way to do so?

Thank you,
Junhwan
