Change colors manually A custom color palettes can be specified using the functions : scale_fill_manual() for box plot, bar plot, violin plot, etc scale_color_manual() for lines and points # Box plot bp + scale_fill_manual(values=c("#999999", "#E69F00", "#56B4E9")) # Scatter ...

Palettes: manually-defined Finally, you can define your own set of colors with scale_fill_manual(). See the hexadecimal code chart below for help choosing specific colors. ggplot(df, aes(x=cond, y=yval, fill=cond)) + geom_bar(stat="identity") + scale_fill_manual(values=c("red", "...
So far, we have only used thedefault color palette of the ggplot2 package. Example 3 explains how to add user-defined colors to our plot. For this task, we have to use the scale_fill_manual function as shown below: ggplot(data, aes(x=group, y=value, fill=group))+# Manually specifi...
