Annotation stem drawn at wrong position when at start of series #1478
Description
When the release is October 2012, which occurs at the start of the time series, the annotation is actually drawn at the November 2012 position, presumably to make space for the label.
The stem of the annotation must occur at the correct position. If there isn't enough space to draw the label to the left of the stem, it should flip automatically to be drawn on the right.
