matplotrecorder

A simple Python module for recording matplotlib animation

It can generate a matplotlib animation movie (mp4, gif, etc.)

This tool use "convert" command of ImageMagick.

Sample gif

Requrements

• ImageMagic

How to use

Call save_frame() at each animation iteration,

And then, call savemovie() for movie generation.

A sample code:

  import matplotrecorder

  print("A sample recording start")
  import math

  time = range(50)

  x1 = [math.cos(t / 10.0) for t in time]
  y1 = [math.sin(t / 10.0) for t in time]
  x2 = [math.cos(t / 10.0) + 2 for t in time]
  y2 = [math.sin(t / 10.0) + 2 for t in time]

  for ix1, iy1, ix2, iy2 in zip(x1, y1, x2, y2):
      plt.plot(ix1, iy1, "xr")
      plt.plot(ix2, iy2, "xb")
      plt.axis("equal")
      plt.pause(0.1)

      matplotrecorder.save_frame()  # save each frame

  # generate movie
  matplotrecorder.save_movie("animation.mp4", 0.1)
  #  matplotrecorder.save_movie("animation.gif", 0.1) #gif is ok.
