Hi, thanks for this great service!
Just a suggestion: it would be nice to have a selectable (or adaptive) scaling of the x-axis. For example, I uploaded a CSV with abt. 60000 Lines, and I got a graphic width of only 1200 pixel, so effectively less than each ~50th sample must have been taken (or some averaging must have been performed). Anyway, with this kind of “downscaling” it’s impossible to “zoom” into the interesting details.
