XY chart throwing exception

I am working in perspective and I am putting an XY chart into a table to display uptime/downtime information for each week. I believe that the XY chart is the part causing the issues because even though this appears to happen sometimes at random it is worse if I manipulate setting on the XY chart.

The chart is still able to render correctly most of the time but we suspect that some of the unreliability is connected to this issue.
