I have a typical line chart in flex and I have two problems that I need help solving.
1. I am trying to display gridlines and vertical fill, but the vertical fill covers the horizontal gridlines it passes over. I can set the alpha really low, but then the fill is almost invisible. Is there a way to get the fill to show up behind the gridlines? 2. I want to show the appropriate datatip when the user mouses over a vertical gridline. Can anyone tell me how to programmatically trigger a datatip? Thank you
