How to display multiple figure with matplotlib?

Question

I try to display 3 figures only one window.

So I have a function make_graph(x) that make a figure of 2 subplots:

%matplotlib
import matplotlib.pyplot as plt
import numpy as np

def make_graph(x):  
    fig = plt.figure()
    ax = fig.add_subplot(2,1,1)
    ax.scatter(x, [x ** 2], s = 50, color = 'blue')
    ax = fig.add_subplot(2,1,2)
    ax.scatter(x, [x ** 3], s = 50, color = 'red')


make_graph(np.arange(10)) #figure_1
make_graph(np.arange(20)) #figure_2
make_graph(np.arange(30)) #figure_3

I want to display this 3 figures in a only one window, but actually, I have 3 windows opening. I don't know how to code this.

Could you help?

No, it doesn't. this post is "how to display multiple subplots". I know how to get subplots (see the def make_graph()) . I only want to display 3 figures in the same window. — Joke, May 15 '20 at 08:54

Set a list of three parameters as arguments to the function and use the So it draws the length of the list for a number of times (three).

import matplotlib.pyplot as plt
import numpy as np

def make_graph(x):  
    fig = plt.figure()
    pos = [[1,2,3],[4,5,6]]
    for i,val in enumerate(x):
        x = np.arange(val)
        ax = fig.add_subplot(2,3,pos[0][i])
        ax.scatter(x, [x ** 2], s = 50, color = 'blue')
        ax = fig.add_subplot(2,3,pos[1][i])
        ax.scatter(x, [x ** 3], s = 50, color = 'red')

make_graph([10,20,30])
