# 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](https://www.imagemagick.org/script/index.php)
|
|
|
|
|
|
# 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.
