deselecting series in legend resizes y axis

[FOCUS electronics]

I have a TeeChart displaying two data series which might be enabled/disabled via legend.
When both series are visible, the chart looks fine:

When disabling the first series, the top axis disappears:

What I recognized is that the left axis IAxisSize property changes but unfortunally I am not able to fix this (manually settings the property shows no effect).

Hello,

Only the axes with an active series are shown. So you may have different axes assigned to each series.
Also note the Walls.Back also can draw that line at the top, when Visible.
If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem.
