The following code will make PlotView's OnMouseDown cannot fire.
The reason could be the invalidate plot function makes PlotView too busy on drawing itself.
Result is:
Cannot make an annotation following mouse cursor and do the mouse down even at the same time.
Possible solution:
Use something like tracker, which doesn't call InvalidatePlot.

//lineAnnotation.X = lineAnnotation.InverseTransform(e.Position).X;
plotModel.InvalidatePlot(false);
};
- Open WPF Example browser.
- Open "Clicking on an annotation"
