Problem

I would like to show chart after each alternation. The problem is that after plt.show() the context is cleared.

Question

How to preserve/restore context of matplotlib after plt.show(), so I can add new data, and then show updated chart?

Note: I did not need to update chart in place, I would like to have 2 charts.

Example

import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.show()

# how to restore context here, so the second graph will also contain first one data
plt.plot([3,2,1])
plt.show()

Result	Expected

*Note: I did not need to update chart in place, I would like to have 2 charts.* But you are showing a combined graph as expected graph – Ghost Ops Sep 19 '21 at 14:01
Nope, the function plt.show() is invoked twice, so it is not subplot. – MaciejLisCK Sep 19 '21 at 14:04
You can't redraw a given Artist (e.g. a Line2D in this case) from an existing plot onto a new plot – Trenton McKinney Sep 19 '21 at 15:54
