Hi Ole, you can reset the ydata using: ydata = myline.get_ydata() ydata += 50 myline.set_ydata(ydata) # pass new data to line object
or just in-place myline.set_ydata( myline.get_ydata() + 50) after that you need a draw to redraw the figure or a show to show up the result. Does this work for you? best regards Matthias On Wednesday 10 June 2009 12:29:11 Ole Streicher wrote: > Hi, > > I want to change the value of a line in an axes.
