highlight regions in a dot-plot?

Question

[Buffo]

Do you know any tool to add annotations or highlight regions in a dot-plot? like the figure below using Pafr. Pafr is great but has a bug when comparing genomes with different sizes.

if your plot is a ggplot object you can use annotate to add a colored block to your plots. https://ggplot2.tidyverse.org/reference/annotate.html

Yes, it is. I need to highlight multiple regions using a dataframe as input though. I'll take a look, it seems possible using annotate, thanks!
