Is there a way to render annotations as fast as the tracker gets rendererd? I need annotations to move through the plot with the mouse and as soon as I get a lot of data (around 5k points) it really starts to lag.

I call refreshPlot(false) because I thought its not updating the data then. Is there a better way to do that?

Kind regards

I think you need to write a custom tracker control to do this with max performance! Then you can update the graphics of the tracker without changing the graphics of the plot.
