In this post, we will learn how to properly annotate a bars barplot, where there are both positive and negative values/bars in ggplot2. In ggplot2, we can use gem_text() with label option to annotate text or bar heights on a barplot easily. However, when we have a barplot that has both positive and negative bars,… Continue reading How to Annotate Positive and Negative Values in a barplot

How to Color Barplots with R Color Brewer
In this tutorial we will learn to how to color bars in a barplot using R Color Brewer’s color palettes. R Color Brewer package “RColorBrewer” offers numerous color palettes that are useful in common situations. For example, it gives “Sequential” palette for ordered data, “Diverging” palette for highlighting deviations from baseline and “Qualitative” palette for… Continue reading How to Color Barplots with R Color Brewer
