PHP as weakly typed language by default does not really differentiate between "" and 0, so do we here. We accept everything, which can be casted (float, int, but also strings) - which might be expected by people directly insertig stuff fetched from some database or userinput. I would suggest to filter your array before passing to the graph component. We could of course implement such a filter system in the datasets, but this seems the wrong place for me to do this. The default action of array_filter()¹ should work fine for you, to accomplish what you are looking for.
