Subject: Silence pango warning if X or Y-axis label is unset.
X-Git-Url: https://git.cworth.org/git?p=acre;a=commitdiff_plain;h=ffb47f290a9cf9cd9b36ba6ab0905b8f7be8bc6a

Silence pango warning if X or Y-axis label is unset.

Pango emits an annoying warning if we pass it a NULL string, (though
it seems to do the right thing regardless). Quiet it down by passing
it an empty string instead.
