void CBCGPChartDiagram3D::SetProportionalScale ( BOOL  bSet = TRUE)
inline

Defines scaling type or 3D scene.

Call this method to use proportional scene scaling. The default value is FALSE.

Non-proportional scaling tries to fit the scene to the diagram bounding rectangle. Proportional scaling takes the minimum between width and height of the diagram bounding rectangle and fits the scene to a rectangle defined by that minimum.

Parameters
bSetTRUE - set proportional scale;
