I am creating some labels in a for loop

controlP5.addTextlabel("label"+i+j,table[j][i],10,10);


But, how can I reference these, to change the labels again?

I have tried
controlP5.controller("label"+i+j).setLabel("Text");

and
controlP5.controller("label"+i+j).setValueLabel("Text");

but neither work.

There is also a controller.stringValue()
but this doesnt take an argument, so not sure how to use!

Many thanks,

RD
