Charts in Microsoft Dynamics CRM are by default built in 2D. While working on a sales pipeline for example, you may want to see a chart representing it in 3D instead of 2D. This post gives the answer, and it is not easy at all.
First try to export your chart. This export generates the associated XML file.
Once your XML file is exported, look for the tag <Area3DStyle> and change its attribute “Enable3D” from false to true.
