Re: [Matplotlib-users] Arc reporting bogus bounding box?

[Jae-Joon L. <lee...@gm...>]

Jason,

This is now fixed in the svn.

http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/lib/matplotlib/patches.py?r1=7840&r2=7857

Meanwhile, you may use the following workaround.


import matplotlib
import pylab
from matplotlib.path import Path

if __name__ == '__main__':
   pylab.clf()
   ax = pylab.axes([0,0,1,1])
   ax.add_line(matplotlib.lines.Line2D((2, 5), (0.75, 6)))
   arc = matplotlib.patches.Arc((2, 0), 1.5, 1.5, 0.0, 0, 180.0, fill=False)
   arc._path = Path.arc(arc.theta1, arc.theta2)
   ax.add_patch(arc)
   ax.axis('equal')


Note that the current pathces.Arc may update its _path during draw().
So, you may need to do

   arc._path = Path.arc(arc.theta1, arc.theta2)

whenever correct extent of the arc is required (i.e., before calling axis).

Regards,

-JJ
