I'm sorry but I have another n00b question that I can't figure out here. I can't seem to find any examples of this either

I have 2 series I'm plotting with plot() and I want to visualize when they cross each other.
If I use a command like this:
plot("EquityCurve",EquityCurve[0],1,GREEN);
plot("EquityLP",LowPass(EquityLP,66),1,BLUE);
...then it plots those series in separate windows. But I want to see them in the same window crossing over each other.
THANKS
