Hi Nestor,

Thanks for using syncfusion product. We have analyzed your requirements and we like to inform you that you can get the value of point region using points[pointindex].x and points[pointindex].y as follows,

[Code Snippet: JS]

var x = chart.model.series[0].points[index].x;

var y = chart.model.series[0].points[index].y;

We have prepared a sample based on your requirement. Please find the attached sample.

Please let us know if it’s help.
