Description
Showing colors on a graph but not on the legend is inconsistent. My preference would be to show the colors on the legend as well as the main plot. I suppose black everywhere would also be a answer.
Here is the short script to demonstrate the issue:
import pandas, plotnine
from plotnine.data import diamonds
# NB: shapes used by geom_point are defined in plotnine/scales/scale_shape.py
g0 = plotnine.ggplot(plotnine.aes(x='carat', y='price', fill='color'), data=diamonds)
g1 = g0 + plotnine.geom_point(shape=1) # Legend all black
print(g1)
g2 = g0 + plotnine.geom_point(shape='s') # Legend correctly colorized
print(g2)I did try adding parameters 'color=fill' 'color=color' & fill='color' to try and get the legend colorized, but no luck
