Subject: Only generate ticks we care about
X-Git-Tag: v2.5.0~1^2~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c20e57bc8ae86f2881b1f894b1767d95194bada1;p=thirdparty%2FChart.js.git

Only generate ticks we care about

Instead of cloning `me.scaleSizeInUnits` moments and probably throwing the vast majority away, only clone what we need.
