Re: [Matplotlib-users] Non-interactive plotting to window?
Here is a script that solves the problem, based on Goyo's input: ** #!/usr/bin/env python simple_matplot.py -- Repeatedly plots sinusoids (shifted a bit each time). - control returns to the user after each plot; - the old plot is erased between cycles. import numpy as np import matplotlib import matplotlib.pyplot as plt x = np.arange(0.,2.*np.pi,0.02) y = np.sin(x) c = go plt.ion() fig = plt.figure() ax = fig.add_subplot(1,1,1) while c.find(go) -1 : try: del ax.lines[0] except : pass line, = ax.plot(x,y,'-') plt.draw() print stop or go? c = raw_input() x = x + 0.5 ** John Thorstensen wrote: I have a sizeable number of python data-inspection scripts that work as follows: - read some data, or do something with it - plot the data - query the user on the command line and get a response - do what the user commands.

Something like a method to kill mainloop would be ideal. Just make sure you use interactive mode and get rid of the show calls: import matplotlib.pyplot as plt plt.ion() # set interactive mode plt.plot(foo) # plot something bar() # do stuff while the plot is visible plt.close() # if you want to close the plot window from the script This works in mpl 1.1.0 al least with tkagg, gtkagg and qt4agg backends.
