I was able to get the 2010 Chart Web Part to "work" in SharePoint 2013, but I'm having an issue getting the charts to work the way I want them to.
I'm trying to create a pie chart that shows the percentage of tasks that are in a certain status (open, not started, in progress, etc.). However, the chart seems to be taking each task INDIVIDUALLY and giving it a piece of the chart. So, right now I just have a chart that says Not Started over and over again (there are over 100 tasks, so there's not actually room to include all of them).
I connected the chart to the appropriate list and made the Y field Total and the X field Status. I'm really not sure what I need to do, at this point, to make it work properly.
