XYChart Renders Before dataSources Bindings Are Complete

Here's a video of a stripped down version of the View. There are no message handlers or scripts.
The bindings:

  • For the XYChart, props.dataSources.Down, Slow, and Run are Named Query bindings.
  • xAxes[0].date.range.min and max are Property Bindings to view.custom.startDate and endDate. A transform converts the dates to millis.
  • The date picker components have their props.value binding set to Bidirectional to write to view.custom.startDate and endDate
