Rails + AMCharts with vertical legend

I followed http://railsonth开发者_开发技巧erun.com/2007/10/04/sexy-charts-in-less-than-5-minutes/ to get regular line charts working on my rails app. Now I'm trying to use http://www.amcharts.com/stock/vertical-legend/ but the I seem to be running into issues. Can anyone tell by looking at the tutorial what needs to change to make it work?

Thanks, Elliot
