2. Click on the first series bar and then right click.. and select "Format Data Series"
3. In the Series options, set overlapped to 100% and select OK
4. Select the 2nd data series --> right click and select "Format Data Series"
5. Set Series Options - Overlapped to 100%
6. Set Gap Width to 200% or thereabouts
7. And select Radio Button - Plot series on secondary axis.

Adjust all the above for desired effect
