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()
