Python save plot

This object needs to persist, so it must be assigned to a variable. We've chosen a 100 frame animation with a 20ms delay between frames. The blit keyword is an important one: this tells the animation to only re-draw the pieces of the plot which have changed. The time saved with blit=True means that the animations display much more quickly.. We end with an optional save command, and then a show ...Use pyplot.savefig () method to save generated plot in a file Example: Python3 import matplotlib.pyplot as plt # Creating data year = ['2010', '2002', '2004', '2006', '2008'] production = [25, 15, 35, 30, 10] # Plotting barchart plt.bar (year, production) # Saving the figure. plt.savefig ("output.jpg") # Saving figure by changing parameter valuesIn this tutorial, we would understand how to write a simple python script to plot live stock chart.
