Is there a property on the xamChart which will prevent the "fake" data from displaying? In all cases where I'm using the xamChart, I allow the user to enter some data filters before fetching and binding the data results. Every user I've encountered always wonders why the chart initially loads with the fake data and they always get confused about what they're seeing. Ideally, the chart would just be visible with no series or fake data until data binding with real data.
That worked, but obviously it would be better if we could just disable the default data with a property rather than all the extra code.

maybe we've added a property since then to disable the default data, I'll let you know if I find anything, but as far as I know the above is your best bet. Hope that helps!
