I use a scatter series that contains around 200,000 data points and I noticed that in the DirectX assisted rendering mode (not sure it also applies to the normal non DirectX mode) scatter points are sampled, meaning, not all scatter points are visible on the chart surface.
How can I turn that off to display all data points even if that may affect performance? I chart financial time series and the chart often shows discrete jumps when there are actually many data points in between when zooming in.
Is there an API of extension that would enable time-based average (e.g. average 10 minutes worth of data points) down-sampling of measurements?
Or is resorting to pre-filter provided data points the only option?
