Hi Johannes, The actual data to chart is of course already provided to the 2 series via the dataprovider - the reason I need series 2 renderer to know about series 1 is in order to position the line segments exactly above the series 1 columns as Flex auto adjusts those column positions based on underlying data/position of the moon etc :-)
