Hi JJ, Thanks for that. It works fairly well, but I've noticed that the graph content (the candlesticks) move slightly faster than the x axis. I've added a sleep(0.1) statement to slow things down, and we can see that at the start the first bar is displayed at around 13:15 but by the times is gets to the left, the same bar is then displayed at about 13:00.
Do you have any suggestion on how to improve that? Apart from that, shifting the graph is quite fast. On my machine, I get a frame rate of 30 FPS if I redraw both X and Y axis. The rate goes much higher ( greater than 100 FPS) if I don't redraw the axis.

This requires some knowledge of transformation, but I guess the code is rather self-explanatory. For example, something like below will work (sorry, I haven't actually tested the code) def get_dx_pixel(self, dx_data): tp = self.ax.transData.transform_point x0, y0 = tp((0, 0)) x1, y1 = tp((dx_data, 0)) return (x1-x0) Regards, -JJ > > > Thanks, > > > > Christophe > > > > > > ------------------------------------------------------------------------------ > Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day > trial.
