Developing UI chart from an array

It is a pity that the example in the docs has three series but also three points for each series so it is not entirely clear whether the data array contains one element for each series, and each of those elements contains the data points for that series, or whether the data array contains one element for each set of data points, and each of those contains one point for each series. Looking at the numbers it looks as if it is the former (which is what you have done) but I am not certain. I haven't done this myself. Hopefully someone else can comment. Alternatively perhaps there is an example on the flows website or in the cookbook that will help.
