I am struggling with pyplot from the matlpotlib library. The figure freezes already when I try to create the plot:
plt.figure()
plt.ion()
ax1 = plt.subplot(211) #Here it freezes
plt.title('test', fontsize=8)
plt.xlim(-1700, 1700)
plt.ylabel('x-axis')
plt.xlabel('y-axis')
plt.grid()
plt.show()
...do something else
I have only worked with Pyqt plots, but this time I would like to solve my Problem without multithreading since I do not care if the plot stops my code for a short moment. The problem is, the script does not stop but continues to run and does not wait until the figure is completely created. (time.sleep() does not help). Is there a solution without threads?
Cheers, James
Ps.: If I add a breakpoint after the code and run in debug mode, there is no Problem (obviously).
Is this one working as you want it?
import matplotlib.pyplot as plt
plt.figure()
plt.ion()
ax1 = plt.subplot(211) #Here it freezes
plt.title('test', fontsize=8)
plt.xlim(-1700, 1700)
plt.ylabel('x-axis')
plt.xlabel('y-axis')
plt.grid()
plt.draw() # draw the plot
plt.pause(5) # show it for 5 seconds
print("Hallo") # continue doing other stuff
