Legend Error...

[ishone]

Greetings,

I am having issues adding a Legend to a chart which is loaded through a custom component. I tried placing the Legend in each of the files, but keep getting an error "("Multiple initializers for property 'dataProvider'. (note: 'dataProvider' is the default property of 'mx.charts.LineChart')". Is there a way to create the Legend from scratch (i.e. an array)?

Thanks!

maybe this will help, I can now see the Markers, but no Labels:
