Side note, the reason that the Category Field property shows up in the series definition for your Line chart is that you have specified a model for the series. As long as the series is on the same model as the default for the chart, you don’t need to do this, and it will use whatever field/template you’ve specified in your Category Axis definition. Make sense?

Yep. Add that Category Axis back in, and it should fix the page. Consider using the Axis’s Category Field/Template options rather than the series ones. We’ll work on making it so that everything doesn’t totally blow up if you find yourself in this same scenario (and making it less likely that you do find yourself in this scenario).
