為了實現畫餅圖，自己寫過一段代碼實現：

def (, ):

size =

name =

n = size.shape[0]

= (abs(size) / size) * (1 - abs(size))

= (0, 0)

cmap = plt.("bwr")

= cmap(size / 2 + 0.5)

gs = .(n, n)

gs.(=0, =0)

plt.(=(6, 6), =True)

for i in range(n):

for j in range(i):

ax = plt.(gs[i, j])

ax.pie((size[i, j], [i, j]), =, =None, =None, =False, =90,

=[[i, j], 'w'], =dict(width=1, ='black', =0.5),

=False,

frame=False, =(0, 0), )

ax.(-1, 1)

ax.axis('equal')

for i in range(n):

for j in range(i + 1, n):

ax = plt.(gs[i, j])

ax.([i, j])

ax.['right'].('w')

ax.['top'].('w')

ax.['left'].('w')

ax.[''].('w')

ax.text(0.5, 0.5, round(size[i, j], 2),

# ={"": "w"},

=8,

='', ='')

ax.([])

ax.([])

for k in range(n):

ax = plt.(gs[k, k])

ax.text(0.5, 0.5, name[k], =12, ='', ='')

ax.([])

plt.axis('off')

plt.show()

效果能實現這樣：

目前水平有限，樣本數量超過25的時候畫圖特別慢python畫出相關系數圖python畫出相關系數圖，不知如何改進或者更好的寫法。

跪求指點，謝謝
