I'm trying to add some indicators to ‘Strategy Equity’ chart,

# In Initialize
self.series = Series(symbol + " avg mom", SeriesType.Line, 2, "")
# OnData
self.Plot("Strategy Equity", "MySym", Value)

The value were plotted between Equity and Daily performance, also the scale is bad so it looks like a straight line.

How can I plot the indicator below Daily performance and set y axis scale so that it is visible.

Thank you.
