Remove Labels from ggplot2 Facet Plot in R

  • Last Updated : 24 Oct, 2021

In this article, we will discuss how to remove the labels from the facet plot in ggplot2 in the R Programming language.

Facet plots, where one subsets the data based on a categorical variable and makes a series of similar plots with the same scale. We can easily plot a facetted plot using the facet_wrap() function of the ggplot2 package. When we use facet_wrap() in ggplot2, by default it gives a title to each plot according to the group they are divided into.

Syntax:

plot + facet_wrap( ~facet-variable)

Parameter:

  • facet-variable: Determines the variable around which plots have to be divided.

Here, is a basic facet plot made using the diamonds data frame which is provided by R Language natively. We have used the facet_wrap() function with ~clarity to divide the plot into facets according to their clarity.



Example: Basic plot

R




# load library ggridges and tidyverse
library(ggridges)
library(tidyverse)
  
# Basic facet plot divided according to category cut
# ggplot() function is used to plot the chart
ggplot(diamonds, aes(x=price, y=color, fill=color)) +
  
# geom_density_ridges() function is used to draw 
# ridgeline plot
  geom_density_ridges()+
  
# facet_wrap() function divides the plot in facets 
# according to category of cut
  facet_wrap(~cut)

Output:

Remove labels from Facet plot

We can customize various aspects of a ggplot2 using the theme() function. To remove the label from facet plot, we need to use “strip.text.x” argument inside the theme() layer with argument ‘element_blank()’.

Syntax:

plot + theme( strip.text.x = element_blank() )

Example: Removing the label from facet plot

R




# load library ggridges and tidyverse
library(ggridges)
library(tidyverse)
  
# Basic facet plot divided according to category cut
# ggplot() function is used to plot the chart
ggplot(diamonds, aes(x=price, y=color, fill=color)) +
  
# geom_density_ridges() function is used to draw 
# ridgeline plot
  geom_density_ridges()+
  
# facet_wrap() function divides the plot 
# in facets according to category of cut
  facet_wrap(~cut)+
# strip.text.x parameter of theme
# function is used to remove the label of facet plot
# element_blank() removes the label
theme(strip.text.x = element_blank())

Output:
