Python: aggiungi un segmento di suoneria o un Cuneo a un complotto polare

Question

Ho una trama polare con una sezione specifica che vorrei colorare completamente in rosso (è la sezione contrassegnata tra le due linee rosse. che colorerà quella sezione o è possibile ottenere un settore solido anello utilizzando la raccolta di patch

Ecco il mio script:??

from pylab import * 
import matplotlib.pyplot as plt 
import numpy as np 
import pylab 
from matplotlib.projections import PolarAxes

fig = figure() 
ax = fig.add_subplot(111, projection = 'polar') 


subplot(111,projection='polar') 
theta = arange(1000)*2*pi/1000. 

plot(theta,0.25*ones(1000),'m') #A to B Circle 
plot(theta, 0.65*ones(1000), 'm') # B to C Circle 
plot([0, 0],[0.25,0.65],'m') # A to B 0 degrees line

plot([7*pi/6,7*pi/6],[0.65,1], 'm') # B to C 210 degrees line 

plot([4*pi/3,4*pi/3],[0.65,1],'r', linewidth = 5) # B to C 240 degrees line 
plot([3*pi/2,3*pi/2],[0.65,1], 'r', linewidth = 5) # B to C 270 degrees line 
plot([5*pi/3,5*pi/3],[0.65, 1], 'm') # B to C 300 degrees line 
plot([11*pi/6,11*pi/6],[0.65,1], 'm') # B to C 330 degrees line 

plot([2*pi,2*pi],[0.65,1],'m') # B to C 360 degrees line 




#patches = [Wedge((0,0), 1, 4*pi/3, 3*pi/2)] 
#p = PatchCollection(patches) 
#ax.add_collection(p) 

rgrids((1,1),('','')) 


ax.set_theta_zero_location("N") 
ax.set_theta_direction('clockwise')   

show() 

Answer 1

un cuneo sembra essere il modo per vai, ma di default verrà anche trasformato in coordinato polare Ates. Si potrebbe dare al cuneo la trasformazione degli assi, che funzionerebbe visivamente, ma renderlo difficile se si desidera che i cunei siano tracciati in base ai dati.

Si potrebbe fare come:

ax.add_artist(Wedge((.5,.5), 0.53, 180, 215, width=0.2, transform=ax.transAxes, color='red'))
