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

[John Wise]

Hi Junhwan,

The set_font routine was added about a month ago.

https://bitbucket.org/yt_analysis/yt/pull-request/444/making-tick-labels-use-a-serif-font-by/diff

If you could update your yt installation, this would probably fix this error.

Thanks,
John
