Hi all, great library! Im trying to get this to plot a linegraph smoothly, based on an external device, i expect to see the graph smoothly update 3-4 times per second.
If i edit the example's setData: loop and change the delay to 0.2 it still only updates about once per second or so. I've added a "print 'tick'" i can see that this occurs every 200ms to STDOUT however the graph is still very slow to update? ideas? cheers leigh #!/usr/bin/env python import time import numpy import veusz.embed as veusz # construct a Veusz embedded window # many of these can be opened at any time g = veusz.Embedded('window title') g.EnableToolbar() # construct the plot g.To( g.Add('page') ) g.To( g.Add('graph') ) g.Add('xy', marker='tiehorz', MarkerFill__color='green') # this stops intelligent axis extending #g.Set('x/autoExtend', False) #g.Set('x/autoExtendZero', False) # zoom out g.Zoom(0.8) # loop, changing the values of the x and y datasets for i in range(100000): x = numpy.arange(0+i/2., 7.+i/2., 0.05) y = numpy.sin(x) g.SetData('x', x) g.SetData('y', y) print "tick " # wait to animate the graph time.sleep(0.2) # close the window (this is not strictly necessary) g.Close()
