Hi,
I want to show length of rectangle as I design in attached snapshot by pen. How can I show length of rectangle like attached snapshot?
For creating rectangle I have used this code -

NGraphicsPathSeries pathSeries = new NGraphicsPathSeries();
    NGraphicsPath rectangle = new NGraphicsPath();
    rectangle.AddRectangle(xLocation, yLocation, 10, diameter);
    pathSeries.GraphicsPath = rectangle;
    _cartesianChart.Series.Add(pathSeries);
    pathSeries.DisplayOnAxis(StandardAxis.PrimaryY, true);
    pathSeries.DisplayOnAxis(StandardAxis.PrimaryX, false);
    pathSeries.DisplayOnAxis(visibleXAxis.AxisId, true);
