Hi,

If I create a bubble chart with auto x-range and keep appending bubbles (so the xrange grows over time to show all the data), after a while some of the bubbles will start to flash on and off. Its as though if they are centred between pixels then the whole bubble doesn’t get drawn.

Any ideas?

Cheers
Felix

I am trying to find a possible problem why I see the effect in the picture after resizing.
Everything was fine in a sample with very high data sample rates. Now I refactored into my real life code and started using WPF Binding and the like. But now I see this effect on the real life code.

I am already:

  • appending the new data inside a separate worker thread
  • calling suspendupdate on the control
  • using XySeriesData<double, double>. Before that I used XySeriesData<DateTime, double> and thought it was the new DateTime I was using. But still see the effect when I switched back to double.

What I did change from the example to real life:

  • Mainly added databinding for RenderSurface and RenderableSeries. They are only set and changed at the beginning of the test run.

I don’t really know where to check from here on. What else could cause this effect?
