From 3415d8b851307c75a1e8aa16030db9172306df78 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev <stfomichev@yandex-team.ru> Date: Mon, 20 Jan 2014 15:39:38 +0400 Subject: perf timechart: Fix wrong SVG height If we call perf timechart with -p 0 arguments, it means we don't want any tasks related data. It works, but space for tasks data is reserved in the generated SVG. Remove this unused empty space via passing 0 as count to the open_svg.
