Hello, how would you go about in eliminating or getting rid of the trace-legend inside a hovermode window, especifically in ā€˜x unifiedā€™ or ā€˜y unifiedā€™?

For example, in this simple code with hovermode ā€˜x unifiedā€™, how do i get rid of the trace as shown in the photo?

import plotly.express as px

df = px.data.gapminder().query("continent=='Oceania'")

fig = px.line(df, x="year", y="lifeExp", color="country", title="layout.hovermode='x unified'")
fig.update_traces(mode="markers+lines", hovertemplate=None)
fig.update_layout(hovermode="x unified")

fig.show()

Hi @kennethv15 welcome to the forum! Itā€™s not possible to remove this part of the legend, You can hack this behaviour by adding traces with a zero-line width as below, but this is just a hack :slightly_smiling_face:

import plotly.express as px

df = px.data.gapminder().query("continent=='Oceania'")

fig = px.line(df, x="year", y="lifeExp", color="country", title="layout.hovermode='x unified'")
fig.update_traces(mode="markers+lines", hovertemplate=None, hoverinfo='skip')
fig2 = px.line(df, x="year", y="lifeExp", color="country", 
                  title="layout.hovermode='x unified'")
fig2.update_traces(hovertemplate=None, line_width=0)
fig.add_traces(fig2.data)
fig.update_layout(hovermode="x unified")
fig.show()
