Dear Biostars,

I am trying to make a scatterplot to show my RNA-Seq log2fold values along all the chromosomal positions for the human genome. Something like this:

 

              |  ***                    ***                  **        *   ***

log2fold |  *    **   ***      *              ***          *    *

              |______|_*___|___**_|_____|_*__|___|__**| ...

                chr1      chr2    chr3     chr4   chr5 chr6 chr7  ...

 

I was thinking on using the chr1,chr2..etc indexes and then simply plot the two vectors, but I run into the problem of labeling each chromosome with its corresponding size. Any help would be appreciated!!
