drawnow for matplotlib

The scientific community often runs iterative code, often in the form of simulation. It's often useful to see the results after each iteration. Accordingly, MATLAB® has a nice feature that allows you to update the figure, drawnow. This repo brings the same feature to Python's matplotlib, with some extras.

Example:

image0

This is shown with imshow, but python-drawnow allows updates of any figure.

Usage:

``` python

complete implementation of script found in test/test.py

from pylab import * from drawnow import drawnow, figure

if global namespace, import plt.figure before drawnow.figure

def approx(x, k): """Approximate x with k singular values""" ...

figure(figsize=(7, 7/2)) def draw_fig(): subplot(1, 2, 1) imshow(x)

subplot(1, 2, 2)
imshow(x_hat)
#show()

x = imread('test-data/mandrill.png').mean(axis=2) kvalues = around(logspace(0, 2, num=10)) for k in kvalues: xhat = approx(x, k) drawnow(drawfig) ```

Documentation

If you want to wait for confirmation after update or the option to drop into a debugger, call drawnow(function_to_draw_figure, confirm=True).

If you only want to show the figure once, call drawnow(function_to_draw_figure, show_once=True). The full documentation is included in the doc strings. Use drawnow? or help(drawnow) to see these docs.

Jupyter/Spyder

Try running the folloowing code in a Jupyter input cell/in the console/etc:

%matplotlib

This will disable the Matplotlin inline mode and use the default plotting backend. For more detail, see the IPython plotting documentation.

Installation

Two options:

  1. Run pip install drawnow.
  2. Download this repository and run python setup.py install.

Option 2 assumes a working Python installation with pip. I suggest Anaconda's distribution: https://www.anaconda.com/distribution/ For other options, see https://realpython.com/installing-python/.

Changes to code

This does require small changes to your code. All it should really amount to is moving figure(); plot(...); show() inside a function; not much.
