How to Create Multiple Charts in Matplotlib and Python   

To create multiple plots in Matplotlib and Python we need to use plt.figure() in order to create separate plots.

Steps

• Import library - matplotlib
• Select data to be plot
  • select the columns which will be used for the plot
• Loop over the selected data
• Create plot figure and select figure size
• Set title for each plot
• Select chart type
  • barplot
  • boxplot

Data

For this example we will create evenly spaced numbers over interval - 0 to 10 - by np.linspace( 0,10 )

Then we will plot the function np.cos().

The data will look like:

To plot multiple plots we will increase the initial value

Example

So to plot multiple plots with matplotlib we need to provide the plt.figure()

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace( 0,10 )

for n in range(4):
    y = np.cos( x+n )
    plt.figure(figsize=(12,5))
    plt.title('chart:' + str(n))
    plt.plot( x, y )

plt.show()

Output

plt.figure(figsize=(12,5))
