Flex - 图表的图例放置

I would like to be able to specify the placement of a legend for a linechart. Currently, it continues to appear to the right of the chart. I have tried playing with the width/height of the chart to no avail... Putting the legend before the linechart in the mxml causes it to appear to the left. I can't seem to get it appear at the bottom though. I can't seem to find any good examples for this. They don't seem to specify anything but the legend usually shows up below the chart, I can't seem to do it. Optionally, it would be okay to somehow minimize the legend..I would like to be able to specify the placemen
