[Matplotlib-users] Annotate Behaviour - Arrows Missing

Running the leach_kinetics.py script and annotating the graph should display two annotations indicating the position of relevant phenomena. However, attached are two outputs, 1) as_script.pdf shows the output of the script (note the missing annotations) and 2) a panned image showing the presence of the annotation when the origin is moved into the visible area of the axes.

There seems to be some strange clipping behaviour (not too sure if that is the correct term) with respect the the drawing (or not) of the arrow. It appears that if the arrow begins or ends on the axes then it is not drawn. Verification of this and tips for a matplotlib tweak to prevent it from happening would also be appreciated?

Kind Regards,

Kurt
