Hello!

I use NRoundedRectangularCallout to mark last points of each line.

NRoundedRectangularCallout rectangularCallout = new NRoundedRectangularCallout();
rectangularCallout.ArrowLength = new NLength(15, NRelativeUnit.ParentPercentage);
rectangularCallout.ArrowBasePercent = 10;
rectangularCallout.FillStyle = new NColorFillStyle(Color.White);
rectangularCallout.UseAutomaticSize = true;
rectangularCallout.Orientation = 0;
rectangularCallout.Anchor = new NDataPointAnchor(line, line.Values.Count - 1, ContentAlignment.BottomCenter, StringAlignment.Center);

The result is on the picture "1.png". You can see that some callouts are overlaped.

I need something like this: see "2.png" (I manually change the callouts location).
Сallouts are one under the other and not overlap each other. How can I achieve this by code?

How can I change the horizontal alignment of data label?
There is only "VertAlign" property.

Need something like this:

NDataLabelStyle label = new NDataLabelStyle();
label.VertAlign = VertAlign.Center;
label.HorizontalAlign = HorizontalAlign.Right;
