BarChart3D

BarChart3D[{{z₁₁, z₁₂, ...}, {z₂₁, z₂₂, ...}, ...}]
generates a three-dimensional bar chart using the matrix of heights z_ij.

BarChart3D[{{{z₁₁, style₁₁}, ...}, ...}]
uses a specific style for each bar.

BarChart3D[{{{x₁, y₁, z₁}, style₁}, ...}]
generates a bar chart of bars scattered at specific x and y coordinates with height z and a specific style.

To use BarChart3D, you first need to load the Bar Charts Package using Needs["BarCharts`"].

BarChart3D has the same options as Graphics3D, with the following additions and changes:

BarSpacing	0	space between bars in the x and y directions
BarEdges	True	whether to draw the edges of bars
BarEdgeStyle	GrayLevel[0]	style for edges of bars
