在plot()时就指定图例labels,再直接调用legend()就好了,或者在plot中指定plot elements,然后通过set_label函数指定图例labels 1plt.plot([1, 2, 3], label='Inline label')2plt.legend()34line, = plt.plot([1, 2, 3])#此处的逗号非常重要,如果没有的话line是一个list对象;加上的话line是一个matplotl...
Legend图例 给图做图例,只需要在plt.plot()加上label参数即可,然后执行plt.legend()即可 x=np.linspace(-2,2,50) y1=2*x+1 y2=x**2 plt.plot(x,y2,label='up') plt.plot(x,y1,color='red',linewidth=1.0,linestyle='--',label='down') ...

Looking atyour last plotit appears that "MACDh" in the legend somehow picked upgreeninstead ofblue. I can't see why because the code is not posted, which leads me to my second item: Would you mind postingyour final complete codehere for all to see?That will be most helpful and very...
