Visualising discrete wavelet transforms: updated for RapidMiner v8

I revisited a previous post about visualising discrete wavelet transforms because I wanted to remember how I did something. The process is quite old and did not work first time with version 8 of RapidMiner Studio. There have been some subtle changes with respect to the requirements for the type of attributes for the "Join" and "De-Pivot" operators. Never fear, I've updated the process and it's here.

Here is the money shot to prove it still works

An interesting feature of this process is the way it uses the "De-Pivot" operator to transform a matrix-like example set into x,y,z coordinates that can be plotted.
