wwplot is broken: AttributeError: 'Legend' object has no attribute 'set_draggable'

While updating the FreeBSD port I found this problem:

$ wwplot 
Attribute Qt::AA_EnableHighDpiScaling must be set before QCoreApplication is created.
Traceback (most recent call last):
  File "/usr/local/bin/wwplot", line 20, in <module>

Both 0.0.7 and 0.0.8 have this problem.

Which matplotlib version do you have? Here on Linux I have version 3.1.2 and it has this method.

[yurivict]

I have matplotlib-2.2.4 because there's some sort of incompatibility of matplotlib-3 with python-2.7

[wwmm]

As far as I could see the "missing" method was added in version 3.0.

Python 2.7? I think that matplotlib 3 is intended for Python 3. That may explain why it was not compatible.
