It seems to me that the XY chart has a bug in Gantt mode.  
If the end time range is between tick, it fills the gap or leaves it empty.

Here’s what I had to do in order to make everything work:

1. _ **xAxes.0.date.range.max** _ and _ **xAxes.0.date.range.min** _ must be set, and they must use dates converted into milliseconds. If you use normal dates it doesn’t seem to work.
2. You must have a record that exists outside of the min and max date ranges. In order to ensure this, I add a record that has _ **fromDate = 0** _ and _ **toDate = 1** _ for every person.

Here’s a view that should demonstrate this.
