Nice. I don't see a lot of charting examples but this is nice because I'm about to start a project plotting multiple items dealing with commodities and futures and I'm sure I'll need to customize it quite a bit.

I used updateDisplayList to loop through the lineSeriesItems to draw my custom line. What I'm charting is surgical cases by day in a given month. What I wanted to show was a linechart that had weekends colored differently so we'd know why the case counts plateaued. I feel like I've just done my first bit of advanced coding in actionscript. I know this isn't very advanced, but hopefully it will help someone else trying to achieve a similar effect. I've left out some of the logic code, but you'll get the idea. var items:Array = (data as LineSeriesSegment).items; for (var i:int = 0; i < items.length; i++) { // get the graphics object var g:Graphics = graphics; if (isWeekend) { // use weekend lineStyle g.lineStyle(3, 0x990000, 1); } else { // use the weekday lineStyle g.lineStyle(2, 0xF2F2F2, 1); } // move to the starting point if we are at the first item if (i==0) g.moveTo(thisItem.x, thisItem.y); // draw if we are not the last item if (!lastItem) { g.lineTo(nextItem.x, nextItem.y); } } No virus found in this incoming message.
