Subject: Only rotate label while rotation is < maxRotation
X-Git-Tag: 2.0.0-alpha4~13^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d7ab51f29b933659ca2058110e35219d3d002068;p=thirdparty%2FChart.js.git

Only rotate label while rotation is < maxRotation

Checking for <= maxRotation results in a labelRotation of 1 if maxRotation is 0, which doesn't make any sense (and also causes the text to be right aligned not centred)
