into the chart value.
Internal use only, the interface does not guarantee that the pixel corresponds to any valid awt pixel value within the chart component.
Warning: A value transformed to a pixel by
AAxis.AChart2DDataAccessor.translateValueToPx(double)
and then retransformed by
AAxis.AChart2DDataAccessor.translatePxToValue(int)
will most often have changed, as the
transformation from value to px a) has to hit an exact int b) most often
will map from a bigger domain (value range) to a smaller one (range of
chart on the screen).
