Can I not use functions such as math.min and math.max in the function node?

@Lars_Andersson,

Yes, those functions are available in the Function Node. But, it’s going to be `Math.min()` not `math.min()` (capital). Here are the docs for reference:

> **[Math](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math)**
>
> Math is a built-in object that has properties and methods for mathematical constants and functions. It’s not a function object.

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);
