ggplot2 Cheat Sheet

In ggplot, R

ggplot2 is a popular data visualization package in R that allows users to create stunning and informative graphics. Developed by Hadley Wickham, ggplot2 is based on the grammar of graphics, which provides a systematic way of mapping data to visual elements such as points, lines, and bars.

Basic Elements

ggplot()Initializes a plot
aes()Defines aesthetic mappings
geom_*()Adds geometric objects to the plot
scale_*()Modifies the scale of an aesthetic
labs()Adds labels to the plot
theme()Modifies the appearance of the plot

Geometric Objects

geom_point()Adds points to the plot
geom_line()Adds lines to the plot
geom_path()Adds a path connecting points
geom_bar()Adds bars to the plot
geom_histogram()Adds a histogram to the plot
geom_density()Adds a density plot to the plot
geom_boxplot()Adds a boxplot to the plot
geom_violin()Adds a violin plot to the plot
geom_smooth()Adds a smoothed line to the plot

Aesthetic Mappings

xX-axis variable
yY-axis variable
colorColor of the object
fillFill color of the object
sizeSize of the object
shapeShape of the object
linetypeLine type of the object
alphaTransparency of the object


scale_x_continuous()Modifies the X-axis scale
scale_y_continuous()Modifies the Y-axis scale
scale_color_*()Modifies the color scale
scale_fill_*()Modifies the fill color scale
scale_size_*()Modifies the size scale
scale_shape_*()Modifies the shape scale
scale_linetype_*()Modifies the line type scale
scale_alpha_*()Modifies the transparency scale


xlab()X-axis label
ylab()Y-axis label
ggtitle()Plot title
labs()Adds multiple labels
