I'm seeing a rather odd behaviour when plotting (using mpl 3405):
- create a figure with two subplots
- plot something on each axis
- plot an extra something on the first axis USING A SYMBOL
- set axis off
- show()
Result: the second plot won't be shown
However, the second plot will be shown if I follow the same process
without using a symbol, or if I don't switch off the axes.
To illustrate, consider the following code:
from pylab import figure, rand, show
fig = figure()
ax1 = fig.add_subplot(121)
ax2 = fig.add_subplot(122)
ax1.plot(rand(100))
ax1.plot([50, 60], [.5, .6], '^')
ax2.plot(rand(100))
for ax in fig.axes: ax.set_axis_off()
show()
The second plot (ax2) is not shown. Now, if line 8 is commented, or if a
symbol is not used in line 6, as in:
ax1.plot([50, 60], [.5, .6])
then the two plots are shown as expected.
Looks like a bug to me, right?

Truly an interesting bug. It doesn't show up in PS but does in Agg.
The most likely explanation is that the draw marker function is
setting a clip path that isn't properly getting cleared and subsequent
draws are being clipped to the original axes.
I'll look into it.

Yep this was it -- fixed in svn. Thanks for the clever test case!

Oh, well -- thanks for the very quick fix. Comes in very handy.
