Re: [Matplotlib-users] Annotate Behaviour - Arrows Missing

JJ thanks for the tip unfortunately there was no change. I modified the script for the hax. annotate(...) to include the annotate_clip=False, however there is no change in the behaviour of the arrows. They are not visible until the xy=(a,b) have values for "a" and "b" that are both greater than their respective origin values (0,0), otherwise they remain clipped. I tested this by replacing the "true" value with (1.0e-10,1.0e-10) resulting in the arrow becoming visible. This is a feasible work around for this instance but it may not suit all applications. Is anybody else experiencing the same issue? Is there another setting that I my tweak to overcome this?
