How to add legends and title to grouped histograms generated by Pandas? (Matplotlib)
To add legends and title to grouped histograms generated by Pandas, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a Pandas dataframe with "a", "b", "c" and "d" keys.
- Plot data frame with kind="hist"
- Set a title for the axes.
- To display the figure, use show() method.
Example
from matplotlib import pyplot as plt
import pandas as pd
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
df = pd.DataFrame({'a': [1, 1, 1, 1, 3],
'b': [1, 1, 2, 1, 3],
'c': [2, 2, 2, 1, 3],
'd': [2, 1, 2, 1, 3],
})
df.plot(kind='hist')
plt.title("Grouped Histograms")
plt.show()Output
