Using time labels still drops the first column

[iamjackg]

I'm piping in data that's across three columns and I would like to see all three plotted out, but even if I specify -m time to use time as the x-axis label, the data points from the first column don't get displayed.

As a workaround I've been using a perl one-liner to prepend 1\t to each line, but this seems like a bug.

(kudos on this btw, I was so happy to find a better replacement for termeter!)
