Plotnine legend position is reset after using patchworklib

[iddryg]

I've noticed that my original ggplot legend position is not maintained after patching together. I used...

• theme(legend_position=(.5, -0.02), legend_direction='horizontal')

...to position it underneath each individual ggplot before combining with patchworklib. However, after patching together, the legend goes back to the right side for every sub-plot.

Is this related to the same issue as in #15? Thanks.

I'm sorry for the late response. Could you share the example code that can reproduce the issue you posted?
Now, I have tried to use theme(legend_position=(xx, xxxx), legend_direction='horizontal') as follows. (using plotnine v0.9.0 and patchworklib v0.4.3)

import patchworklib as pw
from plotnine import *
from plotnine.data import *
g1 = pw.load_ggplot(ggplot(mtcars, aes('wt', 'mpg', color='factor(gear)')) 
                    + geom_point() + stat_smooth(method='lm')
                    + facet_wrap('~gear')
                    + theme(legend_position=(.5, -0.2), legend_direction='horizontal'),
                    figsize=(3,3))
g2 = pw.load_ggplot(ggplot(data=diamonds) 
                    + geom_bar(mapping=aes(x="cut", fill="clarity"), position="dodge")
                    + theme(legend_position=(.5, -0.2), legend_direction='horizontal'),
                    figsize=(5, 2))
(g1.outline|g2.outline).savefig()

Actually, patchworklib cannot perfectly reproduce the original legend position in the single plotnine plot, so please adjust according to the output figure.

Hmm, your example looks good. Mine didn't work... You can see the original ggplots have the legend below, but after using patchworklib they get reset to the right. Let me check my versions. Plotnine version 0.8.0, patchworklib version 0.4.2. I'll update and see if that helps.

Okay, I updated versions to plotnine 0.9.0 and patchworklib to 0.4.3 and it looks like yours now! Perfect, thanks.
