Hide legend in plotly express in Python?

In this article, we will discuss how to hide legend in plotly express using Python.

Dataset in use: bestsellers4

The legend appears by default when variation in one object has to be depicted with reference to the other. Legend makes it easier to read a graph since it contains descriptions for the color code or keys used.

Creating a regular plot so that the difference can be apparent

Here we are going to create a scatter plot using dataframe. For this, we will create dataframe from a given dataset.

# import libraries
import plotly.express as px
import pandas as pd

# read dataset
data = pd.read_csv("bestsellers.csv")

fig = px.scatter(data, x="Year", y="Price", 
                 color="Genre")

fig.show()

Output:

Now, to hide the legend, update_layout() function is called with showlegend argument set to false. This simple statement is enough to get the job done.

Syntax:

# import libraries
import plotly.express as px
import pandas as pd

# read dataset
data = pd.read_csv("bestsellers.csv")

fig = px.scatter(data, x="Year", y="Price",
                 color="Genre")
fig.update_layout(showlegend = False)

fig.show()

Output:
