TS2K - How to Plot Implied Volatility?

["ndtrader" <ndtrader@xxxxxxxxxxx>]

I am trying to plot implied volatility, but TS2K does not give me that
option.
In Format Symbol, Settings, the only record type available is Trade Record,
and sometime Split.
I do collect and save Implied Volatility and can see the values in GS, it
just does not make it to charting.
If anybody knows the secret, please let me know.
Thanks.
