How to set the curve style in python:

(1) Use a series of setter methods on the coordinate system

x = np.linspace(0,100,30)  # 0-100要30个
x
axes  = plt.subplot()  #获取坐标系
axes.plot(x,x,x,2*x,x,x/2)  #画三条线
axes.set_title('title')     #设置标题
axes.set_facecolor('gray')  #设置背景色
axes.set_xlabel('x')        #设置X轴标签
axes.set_ylabel('y')        #设置Y轴标签

(2) Use a series of setter methods for lines

plt.plot()The method returns a list containing all lines

Setting each line requires obtaining the line object

x = np.linspace(0,100,30)  # 0-100要30个
x
lines = plt.plot(x,x,x,2*x,x,x/2)  #返回一个包含所有线的列表对象
lines[0].set_linewidth(5)       #设置第一条线的宽度
lines[1].set_linestyle(':')     #设置第二条线的样式
lines[2].set_color('y')         #设置第三条先线的颜色
