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

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.
