Hi, we're having a problem with the markers at points disapearing after zooming in. We have replicated this with slight modifications to the Nevron sample code.

Before zooming, has circles at data points;



After zooming, these disapear


Interestingly, if you zoom in only a bit at a time this doesn't happen. If you carefuly zoom so that only one data point is removed, they keep their circles.

You can see this int the sample code, by adding the following to NStandardLine2DUC.xaml.cs at around line 85

            // configure interactivity
            NCartesianChart cartesian_chart = (NCartesianChart)nChartControl1.Charts[0];
            nChartControl1.Controller.Selection.Add(cartesian_chart);
            nChartControl1.Controller.Tools.Add(new NAxisScrollTool());
            nChartControl1.Controller.Tools.Add(new NDataZoomTool());           
            cartesian_chart.RangeSelections.Add(new NRangeSelection());
            cartesian_chart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible = true;
            cartesian_chart.Axis(StandardAxis.PrimaryY).ScrollBar.Visible = true;

Thanks, Richard.
