There was a bug with this component that may be related to what you are seeing. Looks like it was corrected in 8.1.13.

> Anybody else have issue with XY chart since 8.1.4 I don’t know what the issue is exactly, but when I have an XY chart with a binding with a script for the moment, the chart sometimes display “Component Error” with the detail “Cannot read property ‘dataFields’ of undefined”.
