Is there a way to detach matplotlib plots so that the computation can continue?

matplotlib, plot, python

Solution

Use `matplotlib`'s calls that won't block:

Using `draw()`:

from matplotlib.pyplot import plot, draw, show
plot([1,2,3])
draw()
print('continue computation')

# at the end call show to ensure window won't close.
show()

Using interactive mode:

from matplotlib.pyplot import plot, ion, show
ion() # enables interactive mode
plot([1,2,3]) # result shows immediatelly (implicit draw())

print('continue computation')

# at the end call show to ensure window won't close.
show()

Problem

After these instructions in the Python interpreter one gets a window with a plot: ``` from matplotlib.pyplot import * plot([1,2,3]) show() # other code ``` Unfortunately, I don't know how to continue to interactively explore the figure created by `show()` while the program does further calculations. Is it possible at all? Sometimes calculations are long and it would help if they would proceed during examination of intermediate results.
