I am trying to build a heat map in Excel 2013 based on the United States. I see other postings regarding this on EE, but they are rather old. I have two columns, one is the state abbreviation and the other is a count. I would like to use this information for a heat map. Attached is an example of what I would like to see.
I have done this in Microsoft MapPoint in the past, but think this would work better for me in Excel. I am also looking to use SharePoint Excel Services, so any third party control would have to work in this environment.
Any suggestions would be appreciated, especially free ones!
