Matplotlib provides for more than one subplot in a plot image.

The default is a 1 by 1 grid of plots. Below is a program that provides for a 2 by 2 grid of plots.

Note that, by default, the plot goes from 0.0 to 1.0 on both axes.

Matplotlib supports many image types such as the following.

Note that the gif type (due to copyright issues) is not included. To obtain a gif one needs to generate, say, a png (256 colors) and then use another program, such as ImageMagick, to convert that image to a gif.

The same holds for the bmp image type, which is not used, except in Windows, due to lack of general compression capability.

Here is the Python code [#1]
import matplotlib.pyplot as plt import rsPlot typeList1 = [ "png", "jpg", ] rlen1 = 2 clen1 = 2 plot1 = rsPlot.plot("plot20-1",rlen1,clen1) ax1 = plot1.ax1 i1 = 0 print("") for rpos1 in range(rlen1): for cpos1 in range(clen1): s1 = "plot #{0:d} at r={1:d} c={2:d}".format(i1,rpos1,cpos1) print("{0:s}".format(s1)) ax2 = ax1[rpos1,cpos1] ax2.set_title(s1) i1 += 1 print("") print("Images:") for type1 in typeList1: plot1.save(type1=type1)
Here is the output of the Python code.
(module rsPlot imported) plot #0 at r=0 c=0 plot #1 at r=0 c=1 plot #2 at r=1 c=0 plot #3 at r=1 c=1 Images: ./plot20-1-01.png : 589 x 439 , 23,674 bytes ./plot20-1-02.jpg : 589 x 439 , 54,070 bytes

Here is the image for the 2 by 2 grid of (empty) plots in png format.

Here is the image for the 2 by 2 grid of (empty) plots in jpg format. Note: There are various compression settings for jpg. The default was used here.
