Histogram with tooltip? about ideogram HOT 2 OPEN

Neat idea, @jdhayhurst! Could you give an example use case of how this would be valuable?

from ideogram.

Hey @eweitz!

An example use case for us is that we would like to visualise where on the genome has the most genome wide associations for a given trait (after filtering by significance and combining from multiple GWAS). Users can see roughly where on the genome has the most GWA (annotations) in the histogram view but in order to ask further questions they require more information. With the tooltip, more information about regions/bars of interests can be displayed by hovering their mouse over a bar. The tooltip would display the genomic region that the bar covers and a count of the annotations (magnitude of bar), and ideally a customisable summary/aggregation of the annotation data/metadata.

I'd love to know if this is at all possible.

Thanks!
