For a future reference, this should now be fixed in the v1.1.x branch
which also has been merged into the master branch.

This is a bug. In the current implementation, annotate has a
side-effect that modifies the arrowprops dictionary.
As a workaround, you may do,

arrowprops = dict(arrowstyle='-', relpos=(0, 1))
plt.annotate('Good relpos', (3, 3), xytext = (3, 2),
 annotation_clip=False, arrowprops=arrowprops.copy())


 plt.annotate('No ha/va', (5, 5), xytext = (5, 4),
 arrowprops=dict(arrowstyle='-'),
  ha='left', va='top')


ha and va controls the location of the text relative to the xytext,
and I believe it does work as expected. It has nothing to do with the
starting point of the arrow, which should be controlled by the relpos
parameter.

 This is a bug. In the current implementation, annotate has a
 side-effect that modifies the arrowprops dictionary.
 As a workaround, you may do,

 arrowprops = dict(arrowstyle='-', relpos=(0, 1))
 plt.annotate('Good relpos', (3, 3), xytext = (3, 2),

 annotation_clip=False, arrowprops=arrowprops.copy())


Works for me. Thanks a lot!



  plt.annotate('No ha/va', (5, 5), xytext = (5, 4),
  arrowprops=dict(arrowstyle='-'),
   ha='left', va='top')
 

 ha and va controls the location of the text relative to the xytext,
 and I believe it does work as expected. It has nothing to do with the
 starting point of the arrow, which should be controlled by the relpos
 parameter.


Thanks for clarifying.
