Hello, I have a problem with the anchor of annotation.

I have the Cartesian chart _chart and its legend with these properties:

NLegend legend = new NLegend();

legend.Dock = DockStyle.Top;
legend.Data.ExpandMode = LegendExpandMode.ColsOnly;
legend.FitAlignment = ContentAlignment.TopCenter;

_chart.DisplayOnLegend = legend;

And I have the annotation:
_annotation = new NRoundedRectangularCallout();
_annotation.FillStyle = new NColorFillStyle(Color.Yellow);
_annotation.UseAutomaticSize = true;


I want to show the annotation when I click to legend data item. But the position of annotation is wrong. I think the position corresponds
to legend FitAligment TopLeft. What am I doing wrong?


private void nChartControl_MouseDown(object sender, MouseEventArgs e)
{
NHitTestResult hitTestResult = nChartControl.HitTest(e.X, e.Y);
NLegend legend = _chart.DisplayOnLegend;

_annotation.Anchor = new NLegendDataItemAnchor(legend, hitTestResult.ObjectIndex);
_annotation.Text = "......";

nChartControl.Panels.Add(_annotation);
}

Thanks for your help,
Daniela
