Trouble with number vs string

I’ve got device data coming in that displays ok in a card (or display?) widget but in a line graph it doesn’t . The data is a voltage value from an http source, e.g. 3.65. In the line chart it is showing as a value like 95 or so, I think it’s because it’s not being interpreted as a number. I tried a formula: number(value) but that doesn’t work.

here’s the data:

NM I figured this out. it was showing on the chart but i just couldn’t see it.
