Referring to secondary series in Plot method?

[drmartell]

I realize this is unsupported, so maybe some fellow traders/coders can chime in.

I am interested in applying the VolumeZones indicator to a non-primary series on a chart.

Specifically I guess I need to know if there is a way to apply a bars objects index to a statement like
checkPrice = Bars.GetClose(idx);

Thanks.

drmartell, as a hint / idea you could look into the Pivots indicator code and how it would load a series asyncronous. This should work for other series than the daily used as well.
