You can add 3D charts and surfaces to AnyLogic models with the help of Jzy3d Java library.
This library allows to create various surfaces, scatter plots, bar charts, and lot of other 3d primitives. Each chart is opened in a separate window, so you can display several charts simultaneously.
The following models demonstrate how to use this library.
Demo model (Windows, x64): Charts3D_x64
Demo model (Windows, x32): Charts3D_x32
The detailed API reference is available on Jzy3d website: http://jzy3d.org.
