I am running DSLstats v6.5 on RPi, graphing all stats.
I noticed that all graphs (except ES per hour) showed 24 hours from the time the program started, so in order to get one full day showing on each graph I stopped recording, then restarted recording just after midnight. Most graphs were then redrawn with 00:00 as the first indicated x-value. However the graphs for "SRNM per Band" initially did not display at all until after the next sample was taken, at which point they retained the 'old' initial x-value (22:54), and continued to show the recorded values from 22:54 onwards. This was true both for downstream and upstream graphs.
I then rebooted the Pi, and all graphs restarted with the boot time as the first indicated x-value. After 2 minutes I stopped and restarted recording, and again all graphs
except "SRNM per Band" adjusted to the new recording start time, but the latter continued with the boot time.
Is this a feature or a bug? In order to display the graphs starting at 00:00 each day, I will probably reboot again just after next midnight.
It's not an issue that needs to be addressed with any urgency, as the work-around is quite easy (if you're a night-owl like me)!
