Problems working with previous bar data

[tulanch]

Hello,

I'm new to ninjascript, but not new to programming.

I used the ninjascript tool to create a simple indicator and have been able to plot the following

double plotme = Close[0];

Plot0.Set( plotme );


but nothing plots(draws) when I do the following:

double plotme = Close[0] - Close[1];

Plot0.Set( plotme );


futhermore, nothing plots(draws) using the following:
double plotme = Close[1];

Plot0.Set( plotme );


My ultimate goal is to perform calculations on on EMA(60)[0] and EMA(60)[1], but I ran into into same problems I have with Close[0] and Close[1]

what am I missing?
Any suggested code snippets to review?

thanks, got it working...

Ahhh calculates "all" data on the update...used the following and it's working for me, from tiny acorns come mighty trees


if (CurrentBar < 1)
return;
// Do something
double plotme = Close[0] - Close[1];
Plot0.Set( plotme );
