Subject: graphlib - MDL-20855 fix alignemnt issue with the x-axis.
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=2d0d78befdd81125b32d63ed1e0dd587dd4f14b5;p=moodle.git

graphlib - MDL-20855 fix alignemnt issue with the x-axis.
Labels with a descender (e.g. May) appeared lower than ones without (e.g. Jun).
Text is drawn baseline aligned, not bottom aligned,and so the code was computing the position wrongly.
