The Matplotlib subplot() function can be called to plot two or more plots in one figure. Matplotlib supports all kind of subplots including 2×1 vertical, 2×1 horizontal or a 2×2 grid.

Horizontal subplot
Use the code below to create a horizontal subplot
from pylab import * t = arange(0.0, 20.0, 1) s = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] subplot(2,1,1) xticks([]), yticks([]) title('subplot(2,1,1)') plot(t,s) subplot(2,1,2) xticks([]), yticks([]) title('subplot(2,1,2)') plot(t,s,'r-') show() |
Vertical subplot
By changing the subplot parameters we can create a vertical plot
from pylab import * t = arange(0.0, 20.0, 1) s = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] subplot(1,2,1) xticks([]), yticks([]) title('subplot(1,2,1)') plot(t,s) subplot(1,2,2) xticks([]), yticks([]) title('subplot(1,2,2)') plot(t,s,'r-') show() |
Subplot grid
To create a 2×2 grid of plots, you can use this code:
from pylab import * t = arange(0.0, 20.0, 1) s = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] subplot(2,2,1) xticks([]), yticks([]) title('subplot(2,2,1)') plot(t,s) subplot(2,2,2) xticks([]), yticks([]) title('subplot(2,2,2)') plot(t,s,'r-') subplot(2,2,3) xticks([]), yticks([]) title('subplot(2,2,3)') plot(t,s,'g-') subplot(2,2,4) xticks([]), yticks([]) title('subplot(2,2,4)') plot(t,s,'y-') show() |
