I’ve brought this to the teams to double check, but I’m fairly sure there isn’t a way to adjust the appearance of the time on the x-axis with the time-series panel.
You can use strings on the x-axis for the bar chart, not bar gauge, so I was able to duplicate this table and, without changing anything, it worked OK for bar chart…maybe?

the tooltip in the timeseries displays the day of week, but not the x-axis.
I even tried overriding GF_DATE_FORMATS_FULL_DATE=‘DDDD HH:mm:ss’. Interestingly, that gives the day of the YEAR. This shows on the tooltip, and the date-picker, but has no impact on the x-axis in the time-series, alas…
might be a worthy feature request?
