How to plot many chart in same page using subplot code?

How to plot many chart in same page using subplot code?

It depends on your plot command. If you are using normal plot, you can add subplot and plot inside them. Here is one example I found.
If you can post one line of your code which plots I may be able to find appropriate way to do that.

Code: Select all

Examples illustrating the use of plt.subplots().

This function creates a figure and a grid of subplots with a single call, while
providing reasonable control over how the individual plots are created.  For
very refined tuning of subplot creation, you can still use add_subplot()
directly on a new figure.

Very nice collection for plotting in python.
matplotlib is a collection of plotting functions which resemble Matlab plot methods.

In this address you will find a very helpful tutorial:
