3D Bar Displayer

A 3D bar displayer has the following basic characteristics:


Class	Ilv3dBarChartDisplayer
Category	Single
Inherits from	IlvBarChartDisplayer
Number of real data sets displayed	1
Can be used with all types of projections	Yes
Items drawn	3D bars

The following property is specific to a 3D bar displayer:


Property	Methods	Default Value
Depth of a 3D Bar	getDepth setDepth	IlvChartDisplayerDepth

Figure 8.9 illustrates the fact that a 3D bar displayer can be used with all types of projections. Data sets are represented by 3D bar displayers in a Cartesian chart (using a Cartesian projection) and in a polar chart (using a polar projection).

We can use the 3D bar displayer displaying the gold 3D bars as an example. We can create this displayer by using the following code:


IlvPalette* palette = dpy->getPalette(dpy->getColor(“gold”), dpy->getColor(“red”)); Ilv3dBarChartDisplayer* displayer = new Ilv3dBarChartDisplayer(IlvChartDisplayerWidth, IlvChartDisplayerDepth, palette);


Note: By default, the 3D bars are outlined with the foreground color, the front face is filled with the background color, and the top and the side faces are filled with shadow colors computed from the background color. The 3D bars will be displayed only with the outline if the Drawn Filled property is set to IlvFalse.
