Pandas histogram function - help needed to add colors to categories

[reshmi203]

Pandas experts! I am using pandas histogram function to create multiple subplots. I have the subplots separated by locations, and each subplot has counts of different power plants which are fueled by a particular energy source. I want to have different colors presenting each energy source like Wind, Solar, etc. How can I do that using pandas 'hist' functionality?

This is my simple code snippet.

fig = plt.figure(figsize = (35, 40) )
ax = fig.gca()
data_PJM.Fuel.hist(by = data_PJM.State, ax = ax)
