Subject: Gnuplot: Improve column/probe name display.
X-Git-Tag: libsigrok-0.1.0~509
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=5f8c4cb3633cdde636c497cf7ec4eb79e30e32f6;p=libsigrok.git

Gnuplot: Improve column/probe name display.

This fixes incorrect probe name display if the user explicitly named
probes via '-p 1=CLK' etc.
