I've not seen any reprensentation of this type based on CCI chanel....
This indicator is an hybrid between CCI and MACD.
The CCI MACD line is calculated using a moving average between 2 CCI period a (FastCCI - SlowCCI) aplied on the (Fast + Slow) periods
The CCI signal line is a moving average of (CCI MACD line, on the signal line smoothing length.
The histogram is only the difference between the CCI MACD and CCI Signal line
