I am creating a few datapoints intended to log only certain values.
For example if x is false, for example, there is no valid data to log, so we'll try again next time y changes but no value now.
if (x === true)
z = y;
// z does not get a value
I find that when I don't return a value in a Meta datapoint, it gets logged as a zero (0.0). How do I accomplish this?
