How to hide the colorbar and legend in Plotly Express?

Last Updated : 28 Nov, 2021

In this article, we will learn how to hide the colorbar and legend in plotly express.

Here we will discuss two different method for hiding color-bar and legend, using different examples to make it more clear.

Example 1:

In this example, we are hiding color-bar in Plotly Express with the help of method fig.update_coloraxes(showscale=False), by passing the showscale parameter as False.

Syntax: For color-bar:

fig.update_coloraxes(showscale=False)
fig.update(layout_coloraxis_showscale=False)

Python3

# importing packages
import plotly.express as px

# using the gapminder dataset
data = px.data.gapminder()
data_canada = data[data.country == 'Canada']

# plotting the bar chart
fig = px.scatter(data_canada, x='year', y='pop',
             hover_data=['lifeExp', 'gdpPercap'], color='lifeExp',
             labels={'pop':'population of Canada'}, height=400, title="Geeksforgeeks")

# hiding color-bar 
fig.update_coloraxes(showscale=False)

fig.show()

Output:

Example 2:

In this example, we are hiding legend in Plotly Express with the help of method fig.update_traces(showlegend=False), by passing the showlegend parameter as False.

Syntax: For legend:

fig.update_traces(showlegend=False)
fig.update(layout_showlegend=False)

Python3

#importing packages
import plotly.express as px

# using medals_wide dataset
wide_df = px.data.medals_wide()

# plotting the bar chart
fig = px.histogram(wide_df, x="nation", y=["gold", "silver", "bronze"], title="Geeksforgeeks")

# hiding legend 
fig.update_traces(showlegend=False)

fig.show()

Output:

Example 3:

In this Example, we are hiding legend as well as color-scale in Plotly Express at same time with the help of method fig.update(layout_showlegend=False) and fig.update(layout_coloraxis_showscale=False), by passing the parameter as False in each case.

Python3

# imports
import plotly.express as px

# using elections dataset
df = px.data.election()

# figure setup
fig = px.scatter_ternary(df, a="Joly", b="Coderre", c="Bergeron", hover_name="district", 
    color="total", size="total", size_max=15, symbol ='Coderre',
    color_discrete_map = {"Joly": "blue", "Bergeron": "green", "Coderre":"red"}, title="Geeksforgeeks"
    )

# move colorbar
fig.update_layout(coloraxis_colorbar=dict(yanchor="top", y=1, x=0,
                                          ticks="outside",
                                          ticksuffix=" bills"))
# hiding legend
fig.update(layout_showlegend=False)

# hiding color-bar
fig.update(layout_coloraxis_showscale=False)

fig.show()
