Hi there

I''ve created a 3D Spline chart (see attached) that contains two series and several points.

The problem i''m having is that I want to provide drill down capability for this chart but when I put code into the ChartRegionClick event I find that e.Region.PointIndex is not being populated corectly.

If I click anywhere on the first series e.Region.PointIndex will be -1 unless I click on a line, in which case it returns the Point index of the point I''ve clicked on. However if I click anywhere on the second series e.Region.PointIndex always returns -1 even if I click on a line.

Am I doing something wrong? maybe using the wrong event, In the same application I''m using 3D Pie and 3D Column charts and e.Region.PointIndex is always populated correctly.

Regards

Craig

Hi Craig,

I am able to reproduce the mentioned issue.

You need to click only on the PointIndex not on the other area of the Spline chart.

I have added symbols to the PointIndex of SplineChart to click on to get the desired drilldown effect.

I have attached the sample which helps you to display the 3D Spline and Pie chart with drilldown effect without any exception.

Please kindly let me know if this helps.

Thank you for your interest in Syncfusion products.

Jaya

Hi Jaya

Thanks for your reply, I''ve tried loading the example but I don''t get any symbols on the chart.

I''m just wondering if I need a later version of the chart control? I''m using 4.2.0.37.

Regards

Craig
