Hi Matt,

There is built-in support for callout rearangement, but we're going to implement this feature along with non overlapping data labels for the next release of the control as it is a common problem.

Best Regards,
Nevron Support Team

I have a chart set up where users can click on data and create callouts to label data points. These callouts are of the type NRectangularCallout. However when more than one data point is selected the callouts can overlap. Is there any setting that allows the user to drag the callout boxes and rearrange them or do I have to create my own function to do so?
