heikin-ashi bar help

[lorend]

Iam trying put the heikin-ashi bar study on my chart...When I put it on a new Advanced Default chart...it simply forms a color area on the existing bars...How do I get it to plot as a bar itself? It doesnt create its own subgraph...or change the bars itself...
I am using the eSignal_HeikinAshi.efs. thank you
