Returns or sets a Double specifying the rotation of the directional light source for a three-dimensional chart. Valid settings are between 0 and 360. Read/write.
expression Required. An expression that returns a ChChart object.
The directional light source rotates around the y-axis of the chart.
This example converts the first chart in Chartspace1 to a 3-D Bar chart and sets the lighting options for the chart.
Sub Format3DLightSources() Dim cht3DBar ' Set a variable to the first chart in Chartspace1. Set cht3DBar = ChartSpace1.Charts(0) ' Change the chart to a 3D Bar chart. cht3DBar.Type = chChartTypeBar3D ' Set the intensity of the ambient light. cht3DBar.AmbientLightIntensity = 0.7 ' Set the inclination of the directional light source. cht3DBar.DirectionalLightInclination = 35 ' Set the intensity of the directional light source. cht3DBar.DirectionalLightIntensity = 0.8 ' Set the rotation of the directional light source. cht3DBar.DirectionalLightRotation = 120 End Sub
