animate module

We built postmd.animate module to help to animate the data. This module is based on the matplotlib.animation.FuncAnimation class.

We provided two methods to preview and save the animation. - show(): preview the animation. - save(): save the animation to a file(git, mp4, or avi).

We provide two derived classes: AppendAnimate and CumAnimate.

• CumAnimate class
• AppendAnimate class

Note

We have initialized self.fig, self.ax = plt.subplots() in the base class Animate. Therefore, you can use self.fig and self.ax to customize the figure of animation. See Example for more details.

Customize

The Base class is Animate class. The following method may be overrided in the derived class:

• _init(self): initialize the data in self.ax

• _update_data(self,n): tell FuncAnimation how to update the data in self.ax. n means the n-th frame in the animation. Should return (xdata,ydata).

• _update_frame(self,n): tell FuncAnimation how to update the frame in the animation. n means the n-th frame in the animation. Usually, there is no need to override this method.
