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

The symbols and shadows can be varied by using the style functions SymbolColorScheme() , SymbolStyle() and ShadowStyle() and the labels by using the five style functions LabelTexts() , LabelStyle() , LabelBackground() , LabelBackgroundOptions() and LabelOptions() .

For one-dimensional charts it is sometimes advantageous to move the symbols 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.
