As you know how easy is to draw a 2D (with 2 axis) graphs in Excel. You can also draw 3D chart in Excel, which 3 axes: X, Y and Z.
The procedure is very similar to how you draw a 2 dimension graph. Suppose you have data of quarterly sales in million for the last 10 years, something like following.
See the data carefully. You have 4 x 10 data fields. Just follow these steps:
Select the data including labels, in Insert ribbon tab go to column and select 3-D chart.
And that's it! You've just inserted 3 axis chart.
Right click on bars and select 3-D Rotation to adjust the grade visibility.
Note: For learning purpose use the table shown above (numbers in an increasing pattern). Otherwise the result will be fairly unreadable, since 3D charts just don't work on a 2D surface, unless you actually rotate them and get things in perspective.
