How to Keep Matplotlib Plotting Interactive While Computation Continues?

Interactive Matplotlib Plotting While Computation Continues

In Python, matplotlib is a powerful library for data visualization. However, by default, its "show()" function blocks further computation, prompting the question:

How to detach matplotlib plots to allow concurrent computation?

The answer lies in leveraging matplotlib's non-blocking calls.

Using draw():

This method updates the plot without blocking further execution:

from matplotlib.pyplot import plot, draw, show

plot([1, 2, 3])
draw()
print('Continue computation')

# Show the plot after calculations
show()

Using interactive mode:

Interactive mode allows the plot to update automatically:

from matplotlib.pyplot import plot, ion, show

ion()  # Enables interactive mode
plot([1, 2, 3])  # Plot shows immediately (implicit draw())

print('Continue computation')

# Show the plot after calculations
show()

By utilizing these techniques, you can interactively explore plots while the computation proceeds in the background, enhancing efficiency and allowing for more informed decision-making.
