My problem isn't the draw, because if I add the bitmap to the screen ala this.addChild(tempUI), it works fine (aka it shows up on the screen). It still prints blank though.....also, the printJobOptions.printAsBitmap=true also makes anything always show up blank. Anyone actually used this before :) The example fails if you add this, the example in the helpfile is wrong and there's no comments on it in the live help.
Oh that and my bitmap has a white background even though I set translucent to true when I make the bitmapdata. (var myBMD :BitmapData = new BitmapData(myLineChart.width,myLineChart.height,true);) Thanks for the FinePrint though.....still stuck on this after a few hours, so let me know if ya got any other ideas.
