Unable to plot histogram in pycharm, works fine in terminal

I do exactly the same thing in both macOS terminal and pycharm console:

>>> import matplotlib.pyplot as plt
>>> plt.hist([-94, -89, 88, 55, 45, 44, 43, 42, 1])

        69.8,  88. ]), <BarContainer object of 10 artists>)
>>> plt.show()

plt.hist([-94, -89, 88, 55, 45, 44, 43, 42, 1])

And both use the same interpreter

interpreter1

paths

interpreter2

Edit

The error only happens when using the debugger, otherwise it works fine.

Solution

  • Most likely an issue in PyCharm in relation to MatplotLib I would raise an issue in the PyCharm issue tracker: https://youtrack.jetbrains.com/issues/PY
