The self.lines[0][1] idiom is really ugly. Avoid it with Darren't first suggestions:: self.lines.extend(ax.plot(something)) If the xdata or ydata change in size, you will need to set them both simultaneously: line.set_data(xdata, ydata) JDH ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
