At the moment my application allows to drag one data point. I need to see if I can do it for multiple points. So the user selects an area on the chart and using mouse drag selected points up and down.

Does anybody can help me ??

Hello,

There is no built-in interactivity tool for dragging of multiple data points, but such tool can be implemented. We can send you an example that demonstrates how to implement a multiple data points selection tool. It can be further extended to support dragging of the selected points. Please contact Nevron support email if you are interested.

Best Regards,
Nevron Support Team

I sent a message to the support.

Thanks
