Convert CAN channels into an array

I am logging data from a sensor via CAN messages. To save on bandwidth the sensor creates bins of samples based on measured distance, like when creating a histogram. Each message describes the number of samples in a particular bin. I would like to plot the time history of this data as a 3D waterfall plot.

It appears I need to select an array for the 3D plot. Is there any way I can combine each channel from the CAN messages and combine them into an array? Normally I'd use the math Classification if the data was a single channel of un-binned distance measurements. Sadly that's not an option with this sensor. Thanks for the help!

Dear Scott,

Combining the channels into the array is possible with Formula. Below is an example

This is how the visualisation of the channel looks like in 3D graph.

Attached is also the setup file.
