Can I not use functions such as math.min and math.max in the function node?
Yes, those functions are available in the Function Node. But, it’s going to be
math.min() (capital). Here are the docs for reference:
I tried that earlier, but just figured out that I had to use this syntax:
payload.data.min = Math.min.apply(Math,payload.data.timeSeries);
and not just payload.data.min = Math.min(payload.data.timeSeries);
