WebI 3D bar graph doesnu00B4t look 3D in excel

In Webi I created a vertical grouped bar chart and then I chose the Display option-> 3d look. The graph looks cool in WebI, it looks 3D as I expected, but when I export it to excel it doesn´t show 3D, it looks like if I didn't choose the 3D look option.

Is this an Excel issue or a WebI issue?

What can I do to make the graph look 3D when I export my report to Excel?
