Hi everybody, this is my first post !!
I'm trying to draw an indicator that is a 2D map (similar to a wavelet spectrum), not a single function.
Attached and example.
I've searched the help of Ninjatrader and the reference of Indicator class, without success...

Thanks everybody !

Not sure if it is helpful or not, but take a look at @sefstrat's work on Ehlers Corona indicator:

GDI problem - Ehlers Corona Indicators - NinjaTrader Support Forum

You can also find the actual download indicator somewhere on the NT support forum in Downloads section probably.

Yes, it is exactly what i was looking for ... i will examine the source code.
