Interactive plotting with Python Matplotlib via command line

To get interactive plots, we need to activate the figure. Using plt.ioff() and plt.ion(), we can perform interactive actions with a plot.

Open Ipython shell and enter the following commands on the shell.

Example

In [1]: %matplotlib auto
Using matplotlib backend: GTK3Agg

In [2]: import matplotlib.pyplot as

In [3]: fig, ax = plt.subplots() # Diagram will pop up. Let’s interact.

In [4]: ln, = ax.plot(range(5))  # Drawing a line

In [5]: ln.set_color("orange")   # Changing drawn line to orange

In [6]: plt.ioff() # Stopped interaction

In [7]: ln.set_color("red")
# Since we have stopped the interaction in the last step

In [8]: plt.ion() # Started interaction
