How to set the curve style in python:
(1) Use a series of setter methods on the coordinate systemx = 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Insert picture description here(2) Use a series of setter methods for lines
plt.plot()The method returns a list containing all lines
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
