I am converting some matplotlib code to Plotly.
Does Plotly have something similar to matplotlib fill_between
Code to convert
# ax.fill_between(fcst_t, fcst['yhat_lower'], fcst['yhat_upper'],
#
color='#0072B2', alpha=0.2, label='Uncertainty interval')
I could manage to do something like the below, but I want to fill the area between these two lines with a particular colour.
fig.add_trace(
go.Scatter(x=fcst_t,y=forecast['yhat_lower'],fillcolor='grey',mode='lines+markers',name="yhat_lower"),
row=1,col=1
)
fig.add_trace(
go.Scatter(x=fcst_t,y=forecast['yhat_upper'],fillcolor='grey',mode='lines+markers',name="yhat_upper"),
row=1,col=1
)
go.Scatter
has a fill
keyword that can be used to control the fill behavior. You can read more at this documentation page or by typing help(go.Scatter)
.
import plotly.graph_objects as go
import numpy as np
x = np.linspace(0, 10, 100)
y1 = np.sin(x) + 2
y2 = np.sin(x / 2) + 8
fig = go.Figure([
go.Scatter(x=x, y=y1),
# fill between the endpoints of this trace and the endpoints of the trace before it
go.Scatter(x=x, y=y2, fill="tonextx"),
])
fig
The fill should also work if the two lines have a different number of points!
