How do I generate a list of unique colors dynamically in AS? similar to how Flex does in default charts, except in a per-item fill scenario?
CONTEXT I want to color code an Hlist of categories to match the dot colors in a per-item filled Plot Series. I have an arrayCollection dataProvider that is a list of categories [categoryid,category]. (number of categories is unknown/unlimited). I'd like to generate a unique color number corresponding to each category in the array and update that arrayCollection with the generated color numbers.[categoryid,category,color] I'd like to use this resulting [categoryid,category,color] arrayCollection as a dataProvider to a horizontalList (dynamic legend list) and a PlotChart per-item fill (Ifill) to color code the dots for each category. User clicks on a color/cat in Hlist, filters the dots for the selected category. Colors in the Hlist match the corresponding colors in the plotchart. I know how to color code the horizontalList, build the fillFunction, and do the filterFunction... but I don't know how to generate the unique colors (much like Flex does for the default colors in charts) in a per-item fill scenario. I'm assuming I'd loop through the arrayCollection of categories and update the color dynamically using some color generator? The colors need to be as unique as possible. It would be cool if I could somehow use Flex's built-in default unique colors for chart series in the per-item fill case? I could create a color column in the category table in the database, and store colors there for each one, but seems to me that AS might be a better approach. Thanks! Don
