Metrics: See all channels/versions/

If a snap has a large number of channels or versions being used, the chart tool-tip (in metrics) will not display all of them, and instead collapse some under a last item named “N other”, in which N is the number of omitted actual items.

I believe there should be a way of seeing the whole stats via the UI — as a matter of fact, a work-around is to look for the information in the page source.
