Labels overlapping each other in column chart if the values are too low

In a stacked column chart, the labels overlap each other if the values are too low.


Please help with solution or workaround.

I think this should be implemented in the ColumnSeries or BarSeriesBase class.
If the height of the rectangle is less than the height of the label text, the labels could be hidden.
Moving the labels so they don´t overlap is probably much harder.

Thank you, objo.
