Why do I lose my plots?

[TrendTracker]

Although I've worked with Tradestation's Easy Language for more than 10 years, I'm having difficulty grasping some of the nuance of NinjaScript.

Can anyone tell me why the following will work fine and I get the appropriate plot:


fastEma.Set(SMA(Input, Fast)[0]);
slowEma.Set(SMA(Input, Slow)[0]);

double macd = fastEma[0] - slowEma[0];
double Ymacd = fastEma[1] - slowEma[1];
double macdAvg = (2.0 / (1 + Smooth)) * macd + (1 - (2.0 / (1 + Smooth))) * Avg[1];

Value.Set(macd);
Avg.Set(macdAvg)
Diff.Set(macd);


But after I make the following change the indicator compiles just fine but all plots disappear (line #5 is new):



fastEma.Set(SMA(Input, Fast)[0]);
slowEma.Set(SMA(Input, Slow)[0]);

double macd = fastEma[0] - slowEma[0];
double Ymacd = fastEma[1] - slowEma[1];
double YYmacd = fastEma[2] - slowEma[2];
double macdAvg = (2.0 / (1 + Smooth)) * macd + (1 - (2.0 / (1 + Smooth))) * Avg[1];

Value.Set(macd);
Avg.Set(macdAvg);
Diff.Set(macd);

Thanks in advance.
