After digging like crazy through the archive I can see that there have been a large number of questions related to this exact topic - I think that stems from people mostly not understanding the callback procedures involved.
For example I ultimately did discover the fillfunction callback for the piechart object, but I don't understand how that data gets propogated back to the legend. Right now the legend actually displays a different set of colors. I found a (not quite as effective) alternate solution to my problem by just filling in an array with the colors I want in the order that I expect them - I then use that as the fill source for the chart after I populate it with data. This creates the correct looking chart and legend, but ultimately colors are not explicitly bound to slice - there is a chance things can go wrong, so I'm still interested in the "correct" solution. Also - does *anyone* know how to pull the PieSeries out of a PieChart. Once the chart is populated how do you pull out just the pieseries? If I had a get method for that data I could probably parse it and figure this whole thing out, but I don't have one so far :( --- In flexcoders@yahoogroups.com, "kamelkev" <[EMAIL PROTECTED]> wrote: > > Hi, > > I'm sure someone has run into this before, but I search and search > and find nothing that sounds right. > > I am creating an applet that loads a remote xml document containing > the necessary data I want to render within the pie chart. > > I pass the labels, the "value" for the slice, along with a color - > but it seems that the PieChart object and the related PieSeries object > don't have the ability to "save" this data anywhere.
