I have a sheet that lists servers and their uptime such as

Name | Uptime
Server 1, 100%
Server 2, 100%
Server 3, 98%
server 4, 95%
server 5, 90%

I would like to make a pie chart that would show like
98-100% would show as green
95-97% show as yellow
94<= show as rede

So in this example, a piechart would show a larger wedge of green because it has a count of 3, and yellow would have a count of one with server 4 and server 5 would be red with a count of 1.

The names are not important, just a color'd pie chart showing that x% was green/yellow red.

Any help would be greatly appreciated!
