Subject: Resistribute vib_analyze pylab.hold()s to avoid auto-generated axis.
X-Git-Tag: 0.3~10
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3ca8607af42119f280da77cc7fcfe3242dc38dbc;p=calibcant.git

Resistribute vib_analyze pylab.hold()s to avoid auto-generated axis.

With the previous setup, the first call to hold() created a subplot(111)
axis that the rest of the subplots wrote over.  Ugly.  Better now.
