Get Null point in trackball

[Roi g]

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.

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