Example of how Python draws a pie chart using the Matplotlib library _python

Introduced

Matplotlib is Python's most famous drawing library, which provides a complete set of command APIs similar to MATLAB and is ideal for interactive charting. It can also be conveniently embedded in GUI applications as a drawing control.

Its documentation is fairly complete, and there are hundreds of thumbnails on the Gallery page, which are available after they are opened. So if you need to draw some kind of diagram, just browse/copy/paste it in this page, and basically you can do it.

colors = [' yellowgreen ', ' Gold ', ' lightskyblue ', ' Lightcoral ']
explode = (0, 0.1, 0, 0) # only "explode" the 2nd slice (i.e. ' hogs ')

plt.pie (sizes, Explode=explod  E, Labels=labels, colors=colors,
  autopct= '%1.1f%% ', Shadow=true, startangle=90)

# Set aspect ratio to is equal so That the pie is drawn as a circle.
Plt.axis (' equal ')


plt.savefig (' d:\\pie.png ')
plt.show ()
