How to skip/filter out rows with missing data?

Not sure… I think both would be acceptible.

I want the dips in TulleTemp filled in and connected, like so:

The table I shared before didn’t contain all the columns I use to create ‘TulleTemp’, so maybe that’s why it didn’t look right… I’ve reduced the number, so now TulleTemp is only calculated from the 4 columns before it. But the second last TulleTemp is wrong, because CoolantTank failed to report its value:

I don’t know how, but I just don’t want ‘67.8’ plotted on the graph. I wan’t it omitted and “glossed” over.
