Hi Shweta,
How do you create the label that is overlapped by the cursors?

Hi,
I want to avoid overlapping on label by cursor line.
Is any way to avoid overlapping on text of label by any object?
In chart, I have first added label on point then created cursor using these below lines.
_verticalAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryY;
_verticalAxisCursor.ValueSnapper = new NAxisRulerClampSnapper();
_cartesianChart.Axis(StandardAxis.PrimaryX).Cursors.Add(this._verticalAxisCursor);
_verticalAxisCursor.SynchronizeOnMouseAction = MouseAction.Move | MouseAction.Hover;
_verticalAxisCursor.StrokeStyle = new NStrokeStyle((float) crossAxisLineStyle.Width, crossAxisLineStyle.Color.WindowsFormColor());
_verticalAxisCursor.ValueChanged += new EventHandler(this.OnValueChanged);
_horizontalAxisCursor.BeginEndAxis = (int)StandardAxis.PrimaryX;
_horizontalAxisCursor.ValueSnapper = new NAxisRulerClampSnapper();
_cartesianChart.Axis(StandardAxis.PrimaryY).Cursors.Add(this._horizontalAxisCursor);
_horizontalAxisCursor.SynchronizeOnMouseAction = MouseAction.Move | MouseAction.Hover;
_horizontalAxisCursor.StrokeStyle = new NStrokeStyle((float) crossAxisLineStyle.Width, crossAxisLineStyle.Color.WindowsFormColor());
_horizontalAxisCursor.ValueChanged += new EventHandler(this.OnValueChanged);

Hi Shweta,
We did some additional investigation and currently, there is no way to render text above the cursors, because they are rendered in an overlay on top of the other chart elements. We modified the control to support chart cursors so that they can display attached texts and this feature will be available in the 2021 release coming out soon. For the time being, you can work around this issue using custom overlay painting - check out the following example:

We hope this helps - let us know if you have any questions.
