Is there a way to rename the _time and _value fields in tooltip?

Hi I’m looking at giraffe for drawing some graphs.
Is there a way to rename the _time and _value fields in tooltip?
The table seems to support it but the properties field doesn’t seem to do anything if the type is “line”?

Hello @sake,
I apologize. Unfortunately this isn’t the place to get Giraffe support. I recommend creating an issue on the gh repo. Thank you.
