how to color background on condition matplotlib in python

You can set the background color of a matplotlib figure using the set_facecolor() method. Here's an example that changes the figure background color based on a condition:

main.py
import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [10, 20, 30, 40]

fig, ax = plt.subplots()

if sum(y) > 100:
    fig.set_facecolor('lightgreen')  # set background color to green
else:
    fig.set_facecolor('lightpink')  # set background color to pink

ax.plot(x, y)
plt.show()

In this example, the background color is set to "lightgreen" if the sum of the y values is greater than 100, otherwise it's set to "lightpink". You can adjust the condition to fit your specific needs.
