pattern_shape_map doesn't work in plotly.express

[LasseVDHeydtQC]

See a minimal example below. While color maps work fine, the pattern map is ignored.

import pandas as pd
import plotly.express as px  #version 5.9.0

dummy_data = pd.DataFrame({"A":[2,3,4,3,2,5],"B":[3,6,4,6,5,1]})
px.bar(dummy_data,pattern_shape_map={"A":".","B":"+"}, color_discrete_map={"A":"green","B":"blue"})

This is because when you just pass in a data frame, x/y/color are inferred automatically but not pattern_shape. You'll need to explicitly set pattern_shape="variable" here I believe.

There's also something odd about your example here: the discrete color map is set to green/yellow but the image you pasted has green/blue :)

I see, that works 🚀.
