Pekko Piirola <pekko.piirola@...> sent me an example some time ago that cycles through a data set. Currently this example only works in the GTK backend, but we're actively working on getting a unified GUI interface to allow for this kind of thing. You may also want to take a look at examples/system_monitor.py and examples/dynamic_demo.py which show how to dynamically update a plot. #!/usr/bin/env python2.3 import matplotlib.matlab import gtk import Numeric fig = matplotlib.matlab.figure(1) ind = Numeric.arange(60) x_tmp=[] for i in range(100): x_tmp.append(Numeric.sin((ind+i)*Numeric.pi/15.0)) X=Numeric.array(x_tmp) lines = matplotlib.matlab.plot(X[:,0],'o') def updatefig(*args): updatefig.count += 1 if updatefig.count>59: updatefig.count=0 lines[0].set_data(ind,X[:,updatefig.count]) fig.draw() return gtk.TRUE updatefig.count=1 gtk.timeout_add(200,updatefig) matplotlib.matlab.show()
