英文:
Plotly multiline legend bullets vertical alignment
问题
Consider the following MWE:
import plotly.graph_objects as go
fig = go.Figure()
for i in range(4):
fig.add_trace(
go.Scatter(
x=[1, 2, 3],
y=[i]*3,
name='在多行中分隔的非常长的图例'
)
)
fig.write_html('deleteme.html')
which produces this:
Is it possible to change the alignment of the bullets in the legend to produce this instead? (I made it with Paint)
In the previous trivial example this looks like a whim, however in more complex cases the alignment of the legend bullets makes it really confusing to know which is which:

@ user171780 感谢邀请。
您可以使用legend_valign来调整图例的位置，使用以下代码：fig.update_layout(legend_valign='top')。
此外，您还可以在绘图时添加组，并使用legend_tracegroupgap定义图例之间的距离。
import plotly.graph_objects as go
fig = go.Figure()
for i in range(4):
fig.add_trace(
go.Scatter(
x = [1,2,3],
y = [i]*3,
name = '一个非常长的图例<br>我分为<br>多行的例子',
legendgroup = 'group' + str(i)
)
)
fig.update_layout(legend_valign='top')
fig.update_layout(legend_tracegroupgap=30)
fig.show()

@ user171780 Thanks for inviting.
You can adjust the position of the legend with legend_valign, with the code fig.update_layout(legend_valign='top').
Furthermore, you can adjust the distance between the legend with adding group during plotting and define the distance with legend_tracegroupgap.
import plotly.graph_objects as go
fig = go.Figure()
for i in range(4):
fig.add_trace(
go.Scatter(
x = [1,2,3],
y = [i]*3,
name = 'A very long legend<br>which I break in<br>multiple lines',
legendgroup = 'group' + str(i)
)
)
fig.update_layout(legend_valign='top')
fig.update_layout(legend_tracegroupgap=30)
fig.show()
