Bug report
matplotlib.plot.show always blocks the execution of python script
Code for reproduction
I try plt.show(block=False) , it failed and appear in a small moment then close itself.
Code:
import numpy as np
import matplotlib.pyplot as plt
if __name__ == '__main__':
plt.figure(figsize=(10, 10))
plt.plot(range(5), lw=2, label='Real')
plt.title('Prediction')
plt.legend(loc="best")
plt.show(block=False)
print("---Plot graph finish---")
I try plt.draw() or interactive mode , it failed, too. Check the code below.
Code:
import numpy as np
import matplotlib.pyplot as plt
if __name__ == '__main__':
plt.figure(figsize=(10, 10))
plt.plot(range(5), lw=2, label='Real')
plt.title('Prediction')
plt.legend(loc="best")
plt.draw()
plt.show()
print("---Plot graph finish---")
Above will block until I close it.
Code:
import numpy as np
import matplotlib.pyplot as plt
if __name__ == '__main__':
plt.ion()
plt.figure(figsize=(10, 10))
plt.plot(range(5), lw=2, label='Real')
plt.title('Prediction')
plt.legend(loc="best")
plt.draw()
plt.show()
print("---Plot graph finish---")
Above will appear nothing, or it appear and disappear very fast.
Expected outcome
I can keep the graph and still execute following code without closing the graph
