This can lead to unexpected behavior as matplotlib defaults to a non-interactive backend.

I do not think this is not quite true, the value of $TEMPLATE_BACKEND is set at build time based on what it finds. Some of the wheels we have released do in fact default to Agg (because they are built in very clean environments).

Here is what I observed on my particular installation:
- No user config file:
Qt5Agg(the same backend listed indata/matplotlibrc. - With user config file but
backendis not set in that file:Agg. Naively I would have expectedQt5Aggtoo but it seems that is not the case. This is what prompted this PR.

The AppVeyor failure here is not spurious; this change broke it because the patch for building conda packages no longer applies to the template file. |
