How to add custom chart as second dataseries in strategy?

I use Add(PeriodType.Final2, 1), but it not works - chart add with wrong parameters.

How to set correct parameters of custom chart?

Search for Multi-Time in Ninjatrader help guide, it's clear I think:

 

Code

protected override void Initialize()  {     Add(PeriodType.Minute, 3);     Add("AAPL", PeriodType.Minute, 1); }
