is there any reason why datatable visible on attached screenshot is displayed like this (see attached)?
DataGroupColumn property is set to "Days" and DataLabelsColumn (PlotArea.XAxis.DataLabelsColumn) to "TaskName"... The data is correct but it is displayed under wrong labels.
I checked examples in the documentation and can't see any differences between my way of populating the chart and yours.
Cheers,
Kamil
