Hi Ben,
If you're just looking for a way to have the legend display
different items than the chart, instead of setting the Legend's
dataProvider to the chart, set it to an array of items you want
displayed. In Flex 1.5, I did this by setting the Legend
dataProvider to a copy of the array used for the chart's series
property; I believe the same approach should work in Flex 2 as
well. If you are displaying markers for the legend, you may also
need supporting code to set the markers' fill and stroke styles so
that they match the chart's styles.
