Hi all,
How can I combine onpick events with annotate ?
Any pointer would be appreciated.
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')
line, = ax.plot(np.random.rand(100), 'o', picker=5) # 5
points tolerance
def onpick(event):
thisline = event.artist
xdata = thisline.get_xdata()
ydata = thisline.get_ydata()
ind = event.ind
print 'onpick points:', zip(xdata[ind], ydata[ind]),
ind
ax.annotate('Test',xy=(ind,
ydata[ind]),horizontalalignment='left',verticalalignment='top')
# ax.redraw_in_frame()
fig.canvas.mpl_connect('pick_event', onpick)
plt.show()
Thanks in advance.
Nils
