Python - 沒有繪圖的錯誤欄

Question

我的代碼製作了兩個地塊，但我只想繪製Eobl的地塊。 E必須只有點和誤差線，沒有線連接點。我怎樣才能做到這一點？

import numpy as np 
import pylab as plt 

fig = plt.figure() 
ax = plt.axes(polar=True) 

E = np.array([3.21,3.03,2.69,2.13,1.58,0.98,0.52,0.14,0.03,0.00,0.20,0.63,1.25,2.00,2.60,2.98,3.27,3.32,3.29,3.03,2.71,2.15,1.58, 
    0.98,0.58,0.12,0.01,0.00,0.15,0.58,1.13,1.78,2.47,2.92,3.17,3.29]) 

Eobl = np.array([3.25,3.15,2.87,2.44,1.91,1.34,0.81,0.38,0.10,0.00,0.10,0.38,0.81,1.34,1.91,2.44,2.87,3.15,3.25,3.15,2.87,2.44,1.91, 
1.34,0.81,0.38,0.10,0.00,0.10,0.38,0.81,1.34,1.91,2.44,2.87,3.15]) 

theta = 2*np.pi/360 * np.array(list(range(90, 450, 10))) 

ax.plot(theta, E, "ro", color = '#000000') 
ax.errorbar(theta, E, yerr=0.09, xerr=0.023, capsize=0, color = '#0000ff') 

ax.plot(theta, Eobl, "ro") 
ax.errorbar(theta, Eobl, color = '#ff0000') 

plt.show() 

Answer 1

的fmt參數控制線連接點的格式。您可以使用參數'none'禁用它，即

ax.errorbar(... fmt='none') 

因此，對於您的情況：

ax.errorbar(theta, E, yerr=0.09, xerr=0.023, capsize=0, color='#0000ff', fmt='none')
