Here is a much more elegant solution which can plot all days on the same day in timechart and does not require the use of an app:
| eval series=strftime(_time, "%m-%d") | eval time_delta=(now-_time)/86400,time_day=ceiling(time_delta),_time=_time+time_day*86400 | eval day=case(time_day=0,"Today",time_day=1,"Yesterday",time_day=8,"SD last week") | timechart fixedrange=false sum(count) by day
This allows you to plot any time range by series or to assign nice names in the case statement to each day based on its relation to the current time/day. 86400 is the number of seconds in a day.
