Use this property when the min, max, quartile, median and mean values for each box have already been calculated, for example by a server-side service. When a valid entry is supplied the series renders that box from it instead of recalculating the statistics from the bound sample array; when an entry is missing or invalid the series falls back to the default calculation for that point. An entry must supply Min, Max, FirstQuartile, ThirdQuartile and Median to be considered valid. When the series is bound to a CollectionView the statistics are matched to the source items by item identity, so sorting, filtering and paging keep them aligned without any further work.
