In Flex 3, 'showAllDataTips' is a new property added to charts to show non-interactive data tips. If that is set to true, it shows data tips of all items in the chart's underlying series. If we want to show tips of only some items in a series, we can do that by adding those items in dataTipItems array of the series.
