Script to count host build numbers

Hi,

Our environment has a mixture of hosts on different build numbers. I'm trying to write a script that will show a count of how many hosts are running each build number. That way I can export it to Excel and make a pie graph to show the spread of versions.

Using the ImportExcel module, I can create a pie graph but it counts every single result as a new value to graph

This code "PieChart -title "Test" (Get-VMHost | Select Version, Build)" generates a graph like below

If I could spit out counts like in the table below, I'd be able to create a Pie Chart like this:

Thoughts?
