How to increase the size of bar graph in python (matplotlib)?

Question

I am am trying to plot a bar graph in the following manner:

# importing package
import matplotlib.pyplot as plt
import pandas as pd
  
# create data
df = pd.DataFrame([['A', 10, 20, 10, 30], ['B', 20, 25, 15, 25], ['C', 12, 15, 19, 6],
                   ['D', 10, 29, 13, 19]],
                  columns=['Team', 'Round 1', 'Round 2', 'Round 3', 'Round 4'])
# view data
print(df)
  
# plot grouped bar chart
df.plot(x='Team',
        kind='bar',
        stacked=False,
        title='Grouped Bar Graph with dataframe')

However, the size of the bar graph is very small. What changes should I make in order to make the bar graph bigger both in length and breadth?

Answer 1

You can use the width parameter

df.plot(x='Team',
    kind='bar',
    stacked=False,
    title='Grouped Bar Graph with dataframe',
    width=0.5)

Answer 2

df.plot(x='Team',
        kind='bar',
        stacked=False,
        title='Grouped Bar Graph with dataframe',
        figsize = (10,10))

Result: ( Uncomfortably big bar plot)

For changing the colormap use the colormap parameter.

from matplotlib import cm
...
df.plot(x='Team',
        kind='bar',
        stacked=False,
        title='Grouped Bar Graph with dataframe',
        figsize = (5,5),
        colormap = cm.get_cmap('Spectral') )

Answer 3

See the documentation for pandas.plot. The parameter you are looking for is figsize. Pandas Plot Documentation
