The data Im trying to get into my P5 sketch.js is an array of graph coordinates so the x axis is 1,2,3,4,5… I can’t use these as property keys I would have to concatonate a string in front just to get data in the sketch and then add a routine to strip it again ?? Thats barmy! BUT I had a working sketch using arrays less than a year ago? Like already mentioned must be a bug so Fabric.js it is. Peace V
