fig.canvas.flush_events() -> NotImplementedError

The following code works fine on my OSX. But it doesn't work on Pythonista. Why?
Anyone know how to do dynamic update on Matplotlib? Thanks# import matplotlib # matplotlib.use('TkAgg') # OSX need this import time import numpy as np import matplotlib.pyplot as plt plt.ion() class Plot: def __init__(self): self.deg = np.arange(0, 360, .1) self.rad = np.deg2rad(self.deg) self.cos = np.cos(self.rad) self.fig = plt.figure() self.ax = self.fig.add_subplot(111) self.ax.plot(self.deg, self.cos) self.ax.grid() def run(self, counter=100): for i in range(counter): self.cos = np.roll(self.cos, -30) self.ax.lines[0].set_xdata(self.deg) self.ax.lines[0].set_ydata(self.cos) self.fig.canvas.draw() self.fig.canvas.flush_events() time.sleep(.01) pp = Plot() pp.run()

Matplotlob on pythonista has some limitations, since it is not based on gtk, etc. So just the image back end.
I have an experimental pythonista back end, which allows interactive plots.
