From 6e92349d5a814a3f633a43d9d6bd3b199ef3ad72 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 5 Oct 2012 16:44:47 +0200 Subject: [PATCH] perf diff: Display empty space for non paired samples Currently in 'Baseline' and 'Period Base' columns zero values are displayed in case no pair is found for the sample. This might be confusing, using empty space instead.
