4 years ago https://github.com/Wlodarski/DR-Altimeter/commit/ca22da9ef87f5a26e577bf4f690ab0347cc630ad works. However it can be painfully slow.
Missing:
- a mouseover cursor or some other way to signal that the inset can be clicked to zoom
- while the screen is being redrawn, some "Please be patient"
By clicking on the inset, zoom out to view the entire graph.
