Trying display multiple histograms on single chart from a 2-D array of random number, with each column being a single histogram on the chart.

You could just use two express VIs, e.g. as attached.

(Personally, I would make my own histogram that does not require dynamic data and express VIs.)

Here's a quick draft using plain code. much cleaner. 😉

You can have as many histograms as you like. Modify as needed.
