matplotlibにPatchCollectionを追加するときのTkinterコールバックのTypeError Axes3D

Question

次のコードは、ポリゴンの例hereに適合しています。

import matplotlib.pyplot as plt 
import matplotlib.patches as patches 
from matplotlib.collections import PolyCollection, PatchCollection 
from mpl_toolkits.mplot3d import Axes3D 
from matplotlib import colors as mcolors 

plt.ion() 
fig = plt.figure() 
ax = fig.add_subplot(1, 1, 1, projection='3d') 


def cc(arg): 
    return mcolors.to_rgba(arg, alpha=.6) 

zs = range(4) 
patch_list = [] 
for z in zs: 
    patch = patches.Rectangle((0, 0), 10, 10, color=cc('r')) 
    patch_list.append(patch) 

patch_collection = PatchCollection(patch_list, match_original=True) 
ax.add_collection3d(patch_collection, zs=zs, zdir='y') 
ax.set_xlim3d(0, 10) 
ax.set_ylim3d(-1, 4) 
ax.set_zlim3d(0, 10) 
ax.set_xlabel('X') 
ax.set_ylabel('Y') 
ax.set_zlabel('Z') 

それはPolyCollectionのためにうまく働いたが、私はPatchCollectionに切り替えたとき、私は、次のエラーを取得開始しました：それはバックエンドに関係しているよう

が見える - どのように上の任意の提言を代わりに使用しますか？

Answer 1

PatchCollectionの代わりにPatch3DCollectionを使用する必要があります。

インポートPatch3dCollection：Jannickに私のコメントで述べたように

from mpl_toolkits.mplot3d.art3d import Patch3DCollection 

とはまだPatch3DCollectionを使用して、すなわち、Patch3dCollectionに

patch_collection = Patch3DCollection(patch_list, match_original=True) 

Answer 2

をPatchCollectionを変更するには、へのパッチを取り付けていない、私に問題を与えましたグラフは適切に表示されます。代わりに、私は、個々のパッチを作成して軸にそれを追加し、3Dにそれを変更するために必要な：これは、パッチがプロットされます作ら

zs = range(4) 
colors = ['r', 'g', 'b', 'y'] 
for i, z in enumerate(zs): 
    rect = patches.Rectangle(xy=(0, 0), width=10, height=10, color=cc(colors[i])) 
    ax.add_patch(rect) 
    art3d.patch_2d_to_3d(rect, z=z, zdir='y')
