Hello!
1. Is it possible to remove some symbols and labels from legend? I have tried FillSceneGraph event, but I haven't succeed. Could I get some code to help?
2. I have so many different series in composite chart, so there isn't enought different icons to use in SymbolIcon list ( character, Random, Plus, X, Triangle, Square, Circle, Diamond, UpsideDownTriangle). Is it possible to get more symbols?
If you want a series to be excluded from a legend, set series.Label to an empty string. Any series that doesn't have a label will not be in the legend. FillSceneGraph is a bit tricky, because in some cases you don't know which symbol and text go with which series, but when you loop through the SceneGraph look for primitives that have Path contain "legend" string.
As for the icons, it won't be possible to add custom icons, but you can submit a feature request here:http://devcenter.infragistics.com/protected/requestfeature.aspx
