" included in RAD studio 13 at earliest?" Hopefully we'll get there long before that, it shouldn't be too complicated to resolve.

The example code is useful. It looks, at first glance, like a a bug ...to be investigated. Temporary workaround could be to directly control the Axis Items list after adding the data: Chart2.Axes.Left.Items.Clear; Chart2.Axes.Left.Items.Add(9,seriesC); Chart2.Axes.Left.Items.Add(5,seriesA); Chart2.Axes.Left.Items.Add(8,seriesB);

It may be a pixel rounding issue, some variation between versions, thus hiding the Label as it isn't deemed to have enough space. Test of concept would be to run: Chart1.Axes.Left.LabelsSeparation := 0;
