Python 改变图形线颜色

我正在尝试使用OS X创建一个图形，这是我得到的：

import matplotlib.pyplot as plt
import numpy as np
import scipy as sp
x_series = [22,25,28,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100]
y_series = [113800,101800,87000,78700,61800,49900,39700,32800,25900,21500,17500,14300,11900,9800,8300,6900,5600,4900]
plt.title("Temperature variation of resistance")
plt.xlabel("Temperature(degrees celcius)")
plt.ylabel("Resistance(ohms)")
y_sig = ([100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.])
plt.errorbar(x_series,y_series,y_sig)

我所要做的就是改变图形线的颜色，与错误条形成对比。任何帮助都将不胜感激；到目前为止，我在网上读到的任何东西都不起作用。

使用线条颜色时，错误条可以分别由关键字参数

color

和

ecolor

控制

下面修改的代码将线条颜色设置为黑色，错误颜色设置为红色

import matplotlib.pyplot as plt
import numpy as np
import scipy as sp

x_series = [22,25,28,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100]
y_series = [113800,101800,87000,78700,61800,49900,39700,32800,25900,21500,17500,14300,11900,9800,8300,6900,5600,4900]

plt.title("Temperature variation of resistance")
plt.xlabel("Temperature(degrees celcius)")
plt.ylabel("Resistance(ohms)")

y_sig = ([100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.,100.])

plt.errorbar(x_series,y_series,y_sig, color='black', ecolor='red')

plt.show()
