I should have been clearer - my apologies. chart does *not* do faceting; I transform multiple charts into diagrams and then lay these out in whatever way is appropriate. I can create each chart with identical axes and so get the ggplot experience.

I think to do something like this I need to be able to access the components of a chart and be able to create new sorts of components; I don’t believe the former is possible at the moment although I think the latter is (I recall someone just submitted a pull request to produce histograms).
