Customize R Plots with scale_fill_gradient: Your Guide

Key points Scale_fill_gradient function allows us to create a continuous color gradient based on a numeric variable for our graphs. We can use the scale_fill_gradient function with the ggplot2 package, a powerful and popular R data visualization tool. We can customize the color gradient by changing the low and high colors, limits, breaks, and scale labels. We can apply the color gradient to different types of plots, such as bars, points, lines, and polygons, to enhance the visual appeal and the information of the data. We can also use other functions, such as scale_fill_gradient2 and scale_fill_gradientn, to create diverging or multiple color gradients for your plots. Arguments and options of scale_fill_gradient Argument Description Example low The color for the lowest value of the data low = “red” high The color for the highest value of the data high = “blue” space The color space in which to interpolate the colors space = “Lab” na.value The color for missing values na.value = “grey50” guide The type of le…
