Hello,
In the attached example I would like to have the wedges under the
arrows. Can someone tell me how do this? I tried to follow the tutorial
from http://matplotlib.org/users/artists.html but I didn't really get
it all.
Thank you
from pylab import *
from numpy import ma
import math
import matplotlib.pyplot as plt
from matplotlib.patches import Wedge
X,Y = meshgrid( arange(0,2*pi,1),arange(0,2*pi,1) )
U = cos(X)
V = sin(Y)
def draw_w(x, y, p1, v, ax=None, **kwargs):
if ax is None:
ax = plt.gca()
p1*=180/math.pi
t1= (p1-v)
t2= (p1+v)
c=(x,y)
radius=0.5
w1 = Wedge(c, radius, t1, t2, fc='0.0', ec='None', alpha=1.0, **kwargs)
ax.add_artist(w1)
fig, ax = plt.subplots()
Q = plt.quiver( U, V, color='LightSalmon', edgecolors='LightSalmon')
(a,b)=shape(X)
for i in range(a):
for j in range(b):
draw_w(X[i,j],Y[i,j],X[i,j], 25, ax=ax)
plt.show()
