Only a few days back I realized that it is so easy to convert our 2-d charts to 3-d in CRM 2011.
Steps are as following:-
Open the chart we want to convert to 3-d.
Suppose this is our chart
Select the Export Chart button from the Ribbon
In the exported xml for the chart add the following line (Area3DStyle), before the closing tag of ChartArea.
</AxisX>
<Area3DStyle Enable3D=”True” />
</ChartArea>
</ChartAreas>
Using Import Chart option import it back, this is how now it is gonna look like
One more thing we can also add filter criteria to the fetch used in Chart’s xml.
