ProEssentials可以创建3D柱状图，柱状图的形式包括线框、实体和阴影。类似于Graph control，3D柱状图只需要YData。

Subsets定义沿z轴有多少行，Points定义了沿着x轴有多少列。

SubsetLabels和PointLabels用于行和列的标签。 SubsetColors是用来控制子集柱状条的颜色。

一旦用户提供数据，ProEssentials将构造一个3D柱状图。下面的示例代码显示了如何构造一个简单的3D柱状图。

Dim s As Integer
Dim p As Integer
 
Pe3do1.PEactions = 20
Pe3do1.PolyMode = PEPM_3DBAR
 
Pe3do1.PrepareImages = True
Pe3do1.Subsets = 10
Pe3do1.Points = 10
 
For s = 0 To 9
  For p = 0 To 9
   Pe3do1.YData(s, p) = (5+35*Cos(p*.4))*(5+10*Sin(s*.34))
  Next p
  Pe3do1.SubsetColors(s) = RGB(100+s*18, 100+s*18, 100+s*18)
Next s
 
Pe3do1.SubsetLabels(0) = "Hello"
Pe3do1.SubsetLabels(1) = "World"
 
Pe3do1.PointLabels(0) = "Texas"
Pe3do1.PointLabels(1) = "Washington"
 
Pe3do1.DegreeOfRotation = 309
Pe3do1.ViewingHeight = 4
Pe3do1.FontSize = PEFS_SMALL
 
Pe3do1.PlottingMethod = 1
 
Pe3do1.MainTitle = "3D Bar Chart"
Pe3do1.SubTitle = ""
 
Pe3do1.XAxisLabel = "Points"
Pe3do1.ZAxisLabel = "Subsets"
Pe3do1.YAxisLabel = "Data value"
