Clustered Bar Chart

Excel 2010.
I have 3 separate measures to plot as a cluster, for several products, for several time periods.
All works well except I cannot see a way to display the products name. It seems that on the bottom axis I can show the time period only.
Do I have to rig this to concatenate both product name and month name as a single column ?
Also, strangely, the category legend includes the products name...which is incorrect.
I had to include the products as the 1st data series in order to get the clustering effect.
Anyone experience something like this ?
When I attempted this as a pivotchart, I got closer. They key is the multilevel Category labels setting.
In the case of the pivotchart, the second level was obliterated. I have no idea how to control that as the settings for rotation, etc. seem only to apply to the first level.

Strangely, unsetting "Autoformat" on the horizontal axis solved the problem partially.
Now I can expand that axis and see the axis labels. Strangely, Autoformat should have done this correctly...or at least much better than it did.
So that's a bug.

However, now the secondary axis does not align with the data points properly along the upper part of the chart.
This is a bug. I was using a clustered column pivot chart. I tried everything to make this work....for naught.
