subplot python

Matplotlib’s subplot() function is a versatile tool for creating multiple plots within a single figure. This function supports various arrangements of plots, including vertical (2x1), horizontal (1x2), and grid layouts (e.g., 2x2).

Horizontal Subplot

The following code demonstrates how to set up a horizontal subplot using Matplotlib:

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

You can adjust the subplot parameters to achieve a vertical layout. Here’s how:

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()

Grid Layout with Subplots

For a grid layout of plots (e.g., 2x2), utilize the following 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()
