如何为 go.layout.Shape(type="line"...) 分配标签？
How to assign a label to go.layout.Shape(type="line"...)?
我制作了下图。
该图应用了一些 add_trace，并以 go.Scatter 作为参数。
已创建具有固定 color 属性的 4 go.layout.Shape、type="line" 列表，并使用该列表更新图形布局：fig.update_layout(..., shapes=...)
这些迹线已分配有标签，我们可以在最右边看到它们。
有没有办法添加标签以分配给线条？
您希望您的线条出现在图例中 (https://plot.ly/python/legend/). However, only traces can appear in the legend, not shapes which are a kind of annotation. What you could do is to create the lines using go.Scatter(..., mode='lines'), and then they would appear in the legend. You just need to give the starting and end points in go.Scatter (see https://plot.ly/python/line-and-scatter/)。
