1927867 - Perfherder Graphs view fails to load properly when values include negative values

Status: NEW

Description

[Greg Mierzwinski [:sparky]]

When metrics have negative, and positive values, the graphs view doesn't show the negative ones and it looks like data is missing.

See this graph for an example: https://treeherder.mozilla.org/perfherder/graphs?highlightAlerts=1&highlightChangelogData=1&highlightCommonAlerts=0&replicates=0&series=mozilla-central,181105,1,15&series=mozilla-central,181150,1,15&series=mozilla-central,182976,1,15&series=mozilla-central,183012,1,15&timerange=1209600

These negative background-diff values aren't displayed but should be: https://treeherder.mozilla.org/jobs?repo=mozilla-central&revision=46a2094acb5ec0c35a97399e1270e7c868ceae0c&searchStr=fenix%2Cbackground&selectedTaskRun=AJCX6IloS7eRvNisBEmpcA.0
