Hi everyone. How do you create cross line through subplots? I atteched example in the post below.
Hi @Sank95, I think the only way to do this is using annotations. It’s going to be cumbersome, I fear.
If you combine add_hline() to a go.layout.Shape() it’s not so tedious, see below example:
It will be easier if you define your xaxis ranges though.
from plotly.subplots import make_subplots
import plotly.graph_objects as go
fig = make_subplots(rows=1, cols=2, horizontal_spacing=0)
fig.add_trace(
go.Scatter(x=[1, 2, 3], y=[40, 50, 60]),
row=1, col=1
)
fig.add_trace(
go.Scatter(x=[20, 30, 40], y=[50, 60, 70]),
row=1, col=2
)
fig.update_layout(height=600, width=800, title_text="Line across subplots",
yaxis2={"side": "right"}, xaxis=dict(range=[0,3.5]),
xaxis2=dict(range=[15,45]), showlegend=False)
fig.add_hline(y=55)
fig.add_shape(
go.layout.Shape(
type="line",
yref="paper",
xref="x",
x0=3.5,
y0=45,
x1=3.5,
y1=55,
line=dict(color="black", width=4),
),row=1,col=1)
fig.show()
