Python | Pandas Dataframe.plot.bar

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.

Pandas DataFrame.plot.bar() plots the graph vertically in form of rectangular bars.

Syntax : DataFrame.plot.bar(x=None, y=None, **kwds)



Parameters:
x : (label or position, optional) Allows plotting of one column versus another. If not specified, the index of the DataFrame is used.
y : (label or position, optional) Allows plotting of one column versus another. If not specified, all numerical columns are used.
**kwds : Additional keyword arguments

Returns: matplotlib.axes.Axes or np.ndarray of them

# importing matplotlib

# importing pandas as pd
import pandas as pd
  
# importing numpy as np
import numpy as np
  
# creating a dataframe 
df = pd.DataFrame(np.random.rand(10, 3), columns =['a', 'b', 'c'])
  
print(df)

chevron_right






                        filter_none










Now we will use a function DataFrame.plot.bar() to plot a graph vertically in form of rectangular bars













                                    filter_none
