3D column
 

We current have a 3D column chart that arranged in a 3 by 4 formate (say
X-axis 1, 2, 3 and Z-axis A, B, C, D) with 12 bars in chart.
Currently our data arranged as 3 by 4.
Now, we would like to arranged them as 3 by 2 (X-axis1, 2, 3 and Z-axis AB,
CD).
Or 2 bars side by side for each combination of 6.

We have no problem for 3 by 4 3D chart.
How can we do 3 by 2 3D column chart with 2 bar side by side.

By the way can we just make 3D column chart wider?
(chart oitself, not just chart area).
