Hi list,
I'm trying to annotate points on a graph by drawing a simple line from the
point on the axis to the top left corner of the text. I can't figure out,
how to use pyplot.annotate so that it turns of the arrow head and I can use
horizontalalignment (ha) and verticalalignment (va). When I use
arrowstyle='-' in the arrowprops dictionary ha and va don't work. Instead I
use relpos=(0, 1) in the arrowprops dictionary, which works, but only when
I call the annotate function the first time. Below is a minimal example.
I'm using mpl version 1.0. as part of EPD 7.1 on Mac OS X 10.5.
Any hints on how to achieve my goal would be greatly appreciated!
Best regards,
Markus

The following code reproduces my problem
import numpy as np
import matplotlib.pyplot as plt
data = np.linspace(1,10)
plt.plot(data, data)
anno_args = {
'annotation_clip': False,
'arrowprops': dict(arrowstyle='-', relpos=(0, 1)),
}
plt.annotate('Good relpos', (3, 3), xytext = (3, 2), **anno_args)
plt.annotate('Bad relpos', (6, 6), xytext = (6, 5), **anno_args)
plt.annotate('No ha/va', (5, 5), xytext = (5, 4),
arrowprops=dict(arrowstyle='-'),
ha='left', va='top')
plt.show()
