Why Does Matplotlib Produce a Distorted Plot in PyCharm with Python 3.12?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I am using PyCharm 2023.2.3 and Python 3.12, but my matplotlib plot appears distorted instead of displaying a normal graph. I've tried reinstalling matplotlib, but the issue persists.
Here is the code I'm running:
PYTHONimport matplotlib.pyplot as plt import numpy as np xs = np.array([100, 500]) ys = np.array([300, 800]) plt.plot(xs, ys) plt.show()
The output I get is shown below:
I would appreciate any advice on how to resolve this issue so that the plot displays correctly.

Below are a couple of recommendations to try and resolve the issue:
1. Change the Matplotlib Backend
Sometimes the problem can be caused by the default backend not playing nicely with Python 3.12 and/or PyCharm’s configuration. For example, you can force Matplotlib to use the TkAgg backend by adding these lines before importing pyplot:
PYTHONimport matplotlib matplotlib.use('TkAgg') import matplotlib.pyplot as plt import numpy as np xs = np.array([100, 500]) ys = np.array([300, 800]) plt.plot(xs, ys) plt.show()
This change often forces the plot to open in an external window rather than within PyCharm’s integrated viewer.
2. Adjust PyCharm’s Plot Viewer Settings
If you prefer using PyCharm’s built-in plot display (SciView), check the following:
- Open Settings/Preferences in PyCharm.
- Navigate to Tools > Python Scientific.
- Either disable (uncheck) the "Show plots in tool window" option or confirm that the setting is configured in a way that works for your system.
Disabling the SciView option can help if the integrated viewer is causing issues.
Summary
- Trying a different backend (like TkAgg) may resolve compatibility issues with Python 3.12.
- Alternatively, modifying PyCharm’s settings regarding the scientific plot viewer can help ensure plots display correctly.
These adjustments should help resolve the persistent issue you’re experiencing with your matplotlib plots.

Perhaps you can try to use Py-Plot's object-oriented environment, by substituting as follows:
import matplotlib.pyplot as plt
import numpy as np
xs = np.array([100, 500])
ys = np.array([300, 800])
fig, ax = plt.subplots()
ax.plot(xs,ys)
I dont know if it will help you, but I have also had trouble with my graphs coming out all ascii-art like.
