I created a simple scatter plot and a service routine to print out the
coordinates of the points I pick with the cursor (based on the demo). It works
until I select the pan or zoom cursor. After I zoom or pan, I can no longer
get back to the normal cursor which allows me to "pick" a circle. Even clicking
"home" doesn't help.
The code is shown below
--------------------------------------------------------------------------------
from matplotlib import figure,pyplot
from numpy import linspace,sin,take
fig=pyplot.figure()
ax1=fig.add_subplot(1,1,1) # (numRows, numCols, plotNum)
t=linspace(0,10,100)
y1=sin(5*t)
y2=y1+sin(10*t)
line1=ax1.scatter(y1,y2,picker=True)
def onpick1(event):
ind = event.ind
print 'onpick1 scatter:', ind, take(y1, ind), take(y2, ind)
fig.canvas.mpl_connect('pick_event', onpick1)
pyplot.show()
--------------------------------------------------------------------------------
this is based on the demo at
