I use a NRectangularCallout together with a 2d-LineChart (just a couple of X-Y pairs) - the NRectangularCallout configuration:
m_RectangularCallout.ArrowLength = new NLength(10, NRelativeUnit.ParentPercentage);
m_RectangularCallout.StrokeStyle.Width = new NLength(1); //disable Callout border: = 0
m_RectangularCallout.UseAutomaticSize = true;
m_RectangularCallout.Orientation = iLabelPos;
m_RectangularCallout.Text = oLine.m_sLabel;
_NevronChart.Panels.Add(m_RectangularCallout);
// Anchor the callout to data point #0
NDataPointAnchor anchor = new NDataPointAnchor(line, 0, ContentAlignment.MiddleCenter, StringAlignment.Center);
m_RectangularCallout.Anchor = anchor;
This works as expected. But now I want to change the anchor for the Callout - I tried the following:
1- Approach: Anchor at DataPoint 2
NDataPointAnchor anchor = new NDataPointAnchor(oNevronLineSeries, 1, ContentAlignment.MiddleCenter, StringAlignment.Center);
oCallout.RecalcLayout(NevronChart.View.Context);
oChart.Chart.RecalcLayout(NevronChart.View.Context);
oChart.Chart.Refresh();
Unfortunatly, nothing happens at all. So how can I change the anchor for the Callout?
2. Approach: Using a ScaleAnchor:
oCallout.Anchor = new NScalePointAnchor(oChart.Chart, 0, 0, 0, AxisValueAnchorMode.Show, new NVector3DD(42348.931761342596, 0.0, 0));
oCallout.RecalcLayout(NevronChart.View.Context);
oChart.Chart.RecalcLayout(NevronChart.View.Context);
oChart.Chart.Refresh();
But same as approach 1: Nothing happens at all. So how do I change the anchor to a NScalePointAnchor?
Thanks for the help,
Best regards, Joern
