highlight of a specific point also in zoom

[Wolf]

Hi, I'm using a plot with overview and because that I can zoom in some parte of chart reducing rendered points.

Here the problem: I'm also using highlight but if I use it (as I'm doing) by position it will fail to select the right marker when in zoom, i think I would need to use the method that accept a series and a DataPoint, something like

plot.getPlot().highlight(plot.getModel().getSeries().get(index),  ????);

the problem is indeed how can I retrieve the DataPoint object if I know the series x coordinate in the whole graph? I must keep a copy of DataPoint when I create the chart or can I retrieve somehow from the plot object model?

Thanks
