fromDate and toDate on Time Axis don't limit store data displayed

[slrobertson1]

I may be assuming wrong, but setting fromDate, toDate and constrain = true on a Time axis don't seem to limit the range of records graphed from a store. Should this work? My store records each have a Date field and I want to graph a subset range of values from the store. How can this be accomplished?

For reference, here is my Axis config:

                    {
                        type: 'Time',
                        position: 'bottom',
                        fields: ['localDate'],
                        title: 'Day',
                        dateFormat: 'M d',
                        fromDate: new Date('3/1/12'),
                        toDate: new Date('4/1/12'),
                        constrain: true
                    }

With constrain true it *should* only show the records within the from/toDate configs. We are still in beta so expect a somewhat bumpy ride as we work through bugs.
