How do you overwrite a plot in Python?

Hold
  1. plt.hold(True) will set the figure to add new data rather than overwrite.
  2. plt.hold(False) will set the figure to overwrite the existing data.
  3. plt. hold() will switch back and forth, but this requires that you know the current state so I prefer explictly using True and False .
