The category labels displayed correspond to the ones defined by grCategoryLabel.
The value of categories depends on the chart data.
The percentage of categories is automatically calculated.
The information display can be formatted by grMask.
The modifications performed by grLabel will be taken into account during the next call to grDraw.
