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);

Hi Shweta,
Currently there is no way to achieve this with the built-in chart functionality, but you can implement this annotation using custom painting - for an example please check out:
All Examples \ Custom Painting examples.
Those examples show how you can use code to draw custom shapes / lines on the chart as well as how to convert between model and view coordinate spaces.
