The 1st argument appearanceConstants makes it possible to rotate the chart 90 degrees (appearanceConstants = horizontal) and to add symbols (appearanceConstants = symbol), shadow (appearanceConstants = shadow) and labels (appearanceConstants = label) to the areas. All options can be combined arbitrarily by using a plus sign "+".

The fills, borders, symbols and shadows can be varied by using the style functions FillColorScheme() , FillStyle() , PictureStyle() , BorderColorScheme() , BorderStyle() , SymbolColorScheme() , SymbolStyle() and ShadowStyle() and the labels by using the 4 style functions LabelTexts() , LabelStyle() , LabelBackground() and LabelOptions() .

Furthermore, one-dimensional area charts can be stacked (appearanceConstants = stacked) and drawn proportionally (appearanceConstants = proportional). Proportional charts are automatically stacked. The labeling of stacked charts is explained in combination with the LabelOptions() function.

For one-dimensional charts it is possible to move the polygon points half an interval width so that they do not lie on the interval borders but rather in the middle of the intervals. This can be done by activating the 2nd argument doShiftIntervals = on.
