bug in `plotnine 0.7.0`

I get the following error:

    152         # 1.45 makes the default colourbar wider than the
    153         # legend entry boxes.
--> 154         width = (self.barwidth or _d('legend_key_width')) * 1.45
    155         height = (self.barheight or _d('legend_key_height')) * 1.45
    156         height *= 5

TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'

@has2k1, I figured out what causes the above bug to appear. It only happens with specific plotnine themes. For instance, this code gives the error mentioned in my post above. Note that this code differs from the code you ran without error in previous post only by using a different theme.

So I think in plotnine 0.7.0, geom_bin2d is broken for specific themes:

import pandas as pd
  
from plotnine import *

df = pd.DataFrame.from_records(
            [(0.0, -3.0), (-15.0, -10.0), (-6.0, -7.0),
             (-6.0, -6.0), (-15.0, -15.0)],
            columns=['predicted', 'actual']
            )

theme_set(theme_matplotlib())

p = ggplot(df, aes('actual', 'predicted')) + geom_bin2d()

p.save('plot.pdf')

v0.7.1 is out.
