Do the right and top spines display correctly when the position is set
using 'axes' coordinates?
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
x = np.linspace(0,2*np.pi,100)
y = 2*np.sin(x)
ax = fig.add_subplot(1,1,1)
ax.set_title('centered spines')
ax.plot(x,y)
ax.spines['right'].set_position(('axes',0.1))
ax.yaxis.set_ticks_position('right')
ax.spines['top'].set_position(('axes',0.25))
ax.xaxis.set_ticks_position('top')
ax.spines['left'].set_color('none')
ax.spines['bottom'].set_color('none')
fig.savefig('test.png',bbox_inches='tight')
Notice that the top spine is 0.25 in axes coordinates, where 0 in the
axes coordinates is the *top* of the picture, and positive goes up. I'd
expect that 0.25 in axes coordinates be 25% from the bottom of the
picture, or that the coordinates would be reversed for the top spine and
the top spine would be positioned 25% from the top of the picture.
Having it jump above the picture was a surprise. I noticed the same
sort of issue for the right spine, as illustrated above as well.
Of course, it may be that I'm just not understanding something...
Thanks,
Jason
