It seems to me that -r is only relevant if you are not starting systemd-bootchart at startup. If you start it at startup, then the beginning of the boot and the beginning of the data logging should almost coincide. In that case there will be no large gap to remove from the start of the graph and therefore -r will not be useful. > And it is normal for any files produced, put into /run/log disappear > after a reboot?
