pandas Graphs and Visualizations Plot on an existing matplotlib axis
Example
By default, plot() creates a new figure each time it is called. It is possible to plot on an existing axis by passing the ax parameter.
plt.figure() # create a new figure
ax = plt.subplot(121) # create the left-side subplot
df1.plot(ax=ax) # plot df1 on that subplot
ax = plt.subplot(122) # create the right-side subplot
df2.plot(ax=ax) # and plot df2 there
plt.show() # show the plot
