Matplotlib image not coming up in Visual Studio Code on Mac

Question

I\'m running some basic code in the Visual Studio Code editor on MacOSX:

    import matplotlib.pyplot as plt
    import numpy as np
    x = np.linspace(0, 20         


        

Answer 1

When running matplotlib codes from the terminal, I experience the same kind of hanging of the application after saving the image to a file. In this case, one 'workaround' that has always worked for me is to turn off blocking. Basically alter your code in this way:

import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 20, 100)
plt.plot(x, np.sin(x))
plt.show(block=False)
input('press  to continue')

It's not perfect, but the image is saved correctly and the application stops after you hit ENTER in the terminal. Hope this helps.
