Hi Syncfusion,
I have area series with null point 
when I am moving with the trackball I get the point data
but if the point has null value I don't get the data
is there is a way to get also the null value data when I move the trackball?
Thanks, Roi

Hi Roi,

Thanks for using Syncfusion products.

Regarding “is there is a way to get also the null value data when I move the trackball?”

Yes. You can get the NaN values using OnLabelsGenerated override method of ChartTrackballBehavior. Please download the sample from the following location.

Sample: http://www.syncfusion.com/downloads/support/forum/131208/ze/Trackball_NullPoint-509981733

Please let us know if you need further assistance on this.

Regards,
Saravana Pandian M.
