Color issue with multiple subplots

Community Support
1

The following small example shows a problem with color arrays passed to different subplots. The first subplot is colored with the color array of the second subplot.

from bokeh.plotting import figure, output_notebook, gridplot, show
from bokeh.models import ColumnDataSource
import pandas as pd

df = pd.DataFrame({‘x’:[1,2,3],‘y’:[1,2,3]})

datasource = ColumnDataSource(df)

p1 = figure(plot_width=300, plot_height=300)
r1 = p1.circle(‘x’,‘y’,source=datasource,color=[‘green’,‘blue’,‘green’],size=20)

p2 = figure(plot_width=300, plot_height=300)
#r2 = p2.circle(‘x’,‘y’,source=datasource,color=“blue”,size=20)
r2 = p2.circle(‘x’,‘y’,source=datasource,color=[‘yellow’,‘red’,‘yellow’],size=20)

output_notebook()
p = gridplot([[p1],[p2]])
show(p)

There’s only one data source and you have overwritten the color column. You’ll have you make two differently named columns explicitly for the colors in your data source, and set the “color” spec to that column.

Thanks! That explains the behavior.

Now I can do:

Looks very pretty. It would be great if we can do the colorbar in a more automatic fashion (I implemented this as a separate figure).
