ValueAxis.AxisLine.IsVisible = false does not work!

Do I have to do anything to make the “IsVisible” property work?

codes as below:

chart.ValueAxis.MajorTickMark = TickMarkType.None;
chart.ValueAxis.MinorTickMark = TickMarkType.None;
chart.ValueAxis.TickLabelPosition = TickLabelPositionType.None;
chart.ValueAxis.AxisLine.IsVisible = false;

the AxisLine still appear when I set it to false.
the version I’m using is 2.9.7.0

Please try the latest v3.1 at

V3.1 doesn't seem to solve my problem... the Axisline still appear with the Isvisible = false

Please try this attached fix.
