GeneralizedBarChart

As of Version 7.0, GeneralizedBarChart has been superseded by RectangleChart.

GeneralizedBarChart[{{pos₁,height₁,width₁},{pos₂,height₂,width₂},…}]

generates a bar chart with the bars at the given positions, and with given heights and widths.

GeneralizedBarChart[{list₁,list₂,…}]

generates a bar chart from lists of data.

BarValues	False	whether to show the length of each bar
BarEdges	True	whether edges are drawn around each bar
BarEdgeStyle	Opacity[0.5]	style for the bar edges
