I am using the attached code but seems like stacked chart don't display values correctly
Hello pratik,
To display values in the chart there is a DataSource property to set for each of the series and also setting the ChartType property to one of the stacked series. Using NetAdvantage 11.2 version shows the list of series types and it's requirements from the following link: Chart Types.
As for using the 12.1 version since the xamChart is retired you can use the xamDataChart.
