Example of extracting series X and Y values from groupingModeInfo ?

[Peter]

Hi

Can you give an example how to extract X/Y values from a chart with multiple series using groupingModeInfo ?

var visibleSeriesList = trackballDetails.groupingModeInfo?.visibleSeriesList

How do I get X and Y values?

[Peter]

I got it working. Thanks

Hi

I can get the X/Y value but the values are not correct.

X axis - DateTime

Y Axis - Double values

When the trackball at the chart area, it gives non correct values. Perhaps it has to do with fully zoomed out chart and partially zoomed chart?

Does the zoom factor play a part?

Hi peter 

 

We have analyzed your query and tried to reproduce the reported scenario with the trackball builder property, in that builder property we have added all visible points values as a text widget and check with the chart zoom in and zoom out scenarios. But the issue is not reproduced at our end, we are getting proper x and y values. We have attached the user guide link and sample which we have used for testing that can be found below.

If this is not your case, then could you please elaborate on the scenario or try to reproduce the scenario in the attached sample and get back to us. This will be much helpful in providing the solution sooner.
