Each value is displayed as a bar, the bars of each set can be organized
Each value is displayed as a bar, the bars of each set can be organized
side by side or accumulated.
Each bar of a set is rendered by a QwtColumnSymbol, that is set by setSymbol().
The bars of different sets use the same symbols. Exceptions are possible
by overloading specialSymbol() or overloading drawBar().
Depending on its orientation() the bars are displayed horizontally
or vertically. The bars cover the interval between the baseline()
Depending on its orientation() the bars are displayed horizontally
or vertically. The bars cover the interval between the baseline()
and the value.
In opposite to most other plot items, QwtPlotMultiBarChart returns more
than one entry for the legend - one for each symbol.
