Subject: Format year of monthly tick lables with 2 digits instead of 4.
X-Git-Tag: v1.1.0~31^2~16
X-Git-Url: https://adrianiainlam.tk/git/?a=commitdiff_plain;h=78c0594725dbd1c71220f3f8b6d4ec905baec16f;p=dygraphs.git

Format year of monthly tick lables with 2 digits instead of 4.

Since commit 7b2dfd0 (Oct 15, 2013) the format of monthly tick
labels is `%b %Y` (e.g. Oct 2013). Before the format was '%b %y'
(e.g. Oct 13). Revert to the later format because it seems to be
an accidental change.

  * `dygraph.js`:
    Revert format of monthly tick labels from `%b %Y` to `%b %y`.
