Hi,

Is there a way to allow the user to draw a rectangle and get all the data points within that rectangle?

Thanks

Thanks Dimitar,

 

I have been working on making my own version in the mean time.

Is there anyway to convert physical coordinates to chart coordinates or chart coordinates to physical coordinates?

I have everything working except the coordinates for my rectangle don't match up to the Layoutslot coordinates of the data points.

Hi Tony,

There is a way to do this. You can check the following post which shows it: Draw a chart with a mouse click.

In addition, there is a method that gives you the location of a specific value on the axis:

var axis = radChartView1.Axes[1] as LinearAxis;
var loc = axis.GetLocationOfValue(10);

I want to say that the feature is already completed and it will be released with the new version later today. 

Should you have any other questions do not hesitate to ask.
