Subject: Standardize matplotlib rendering on figure.canvas.draw() and figure.show().
X-Git-Tag: 0.7~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e45528302fbeed1d91cd95e9a0b46c870215ecb4;p=pypiezo.git

Standardize matplotlib rendering on figure.canvas.draw() and figure.show().

In interactive mode, skip the no-op pyplot.show().  In non-interactive
mode, the show() calls will block until the window is closed.
