Interval-Property of DateTimeAxis

[fliebrecht]

Setting in XAML an Interval of DateTimeAxis freezes Visual Studio's XAML-Designer - when not accompagnied with a setting of the IntervalType property. Something like this doesn' t work:

       <chart:Chart.Axes>
            <chart:DateTimeAxis Orientation="X" Interval="1">
       </chart:Chart.Axes>

Something like this works:

       <chart:Chart.Axes>
            <chart:DateTimeAxis Orientation="X" Interval="1" IntervalType="Months">
       </chart:Chart.Axes>

Is that said elsewhere or even obvious?
