Performance Analytics Widget "Previous Period Chart" option put a "1" in front of the period labels.

[johnhebenstreit]

When I use the "Previous period chart" feature on a PA widget, the "Month" labels are prefixed with the number one -->"1"   (see screen shots)

Customers are asking for this to be removed.  Not really sure what it is telling us or how to remove it?  Note: this only happens when the "Previous period chart" option is selected.

Please advise and Thanks
