Plotly in Python：如何在使用matplotlib时添加图例？

Question

In plotly, you can convert a matplotlib figure into plot.ly:

x=[1,2,3] y=[4,5,6] plt.plot(x,y,label='test') fig=plt.gcf()

However, if I add legend,

x=[1,2,3]
y=[4,5,6]
plt.plot(x,y,label='test')
fig=plt.gcf()
plt.legend()

It will return error RuntimeError: Cannot get window extent w/o renderer

I want to know what is the problem? Does plot.ly support legend made with matplotlib?

Answer 1

将showlegend=True添加到plt.plot(x,y,label='test')可以解决问题。
