In this article, we will learn how to set the amount of vertical space between legend groups.

A legend is an area describing the elements of the graph. In the plotly legend is used to Place a legend on the axes.

Example 1: In this Bar chart, We are setting the amount of vertical space (in px) between legend groups with the help of a method called fig.update_layout(legend_tracegroupgap= 2), by passing the legend_tracegroupgap parameter as 2 pixels.

Python3

# importing packages 
import plotly.express as px 
  
# using medals_wide dataset 
wide_df = px.data.medals_wide() 
  
# plotting the bar chart 
fig = px.bar(wide_df, x="nation", y=[ 
             "gold", "silver", "bronze"], 
             title="GeeksforLazyroar") 
  
# spacing legend in plotly in pixels. 
fig.update_layout(legend_tracegroupgap=2) 
  
# showing fig. 
fig.show() 

Output:

Example 2: In this Scatter chart, We are setting the amount of vertical space (in px) between legend groups with the help of a method called fig.update_layout(legend_tracegroupgap= 2), by passing the legend_tracegroupgap parameter as 12 pixels.

Python3

# importing packages 
import plotly.express as px 
  
# using the gapminder dataset 
df = px.data.tips() 
fig = px.scatter(df, x="total_bill", y="tip", color="sex", 
                 symbol="smoker", facet_col="time", 
                 labels={"sex": "Gender", "smoker": "Smokes"}) 
  
# spaceing between legend in pixel. 
fig.update_layout(legend_tracegroupgap=12) 
  
# showing figure. 
fig.show()
