Multiple rows in x-axis (months and years in t-axis)

[Carl Fredrik]

I'm currently working with some data that I need visualized over time since March 2020. I'm using labels for each month, but I'd like a second row of labels for year (under the "Jan" label). I've tried different ways, including using compound double quotes, which gets me halfway, but removed all the formatting I have on my text. I was wondering if there is any solution to this, or if I can simply superimpose a second x-axis (or rather t-axis).

If someone would know how to also add a different major tick type with the years that would also be excellent, preferably with a stronger line than what I have.

Here is a code example:

twoway (tsline test2, lcolor(black) lwidth(medthick) ) ///
    if(date >= 21975 & date <= 22646), /// 
    xtitle("", size (small)) ///
    ytitle("", size(small)) ///
    graphregion(margin(l+0 r+5 b+1 t+0 )) ///
    graphregion(color(white)) plotregion(color(white)) /// 
    title(" ") legend(label(1 "Test") label(2 "") label(3 "") label(4 "") label(5 "") label(6 "")  size(small) position(12) region(style(none)) row(2) ) ///
    note("I'd like to have useful labels on my tscale", size (vsmall)) ///
    yscale(range(1.05)) ytick() ymtick() ylab(1 "0%" 0.8 "-20%" 0.6 "-40%", angle(0) labsize(8pt) grid glcolor(gs15) glwidth(medthick)) ///
    tscale(range(21975 22464)) ttick() tmtick() tline() tlab(21975 "Mar" 22006 "Apr" 22036 "May" 22067 "Jun" 22097 "Jul" 22128 "Aug" 22159 "Sep" 22189 "Oct" 22220 "Nov" 22250 "Dec" 22281 `" "Jan" "2021" "' 22312 "Feb" 22340 "Mar" 22371 "Apr" 22401 "May" 22432 "Jun" 22464 "Jul" 22493 "Aug" 22523 "Sep" 22554 "Oct" 22585 "Nov" 22616 "Dec" 22646 `" "Jan" "2022" "', angle(45) labsize(8pt) grid glcolor(gs15) glwidth(medthick))

I realize that much of the code is superfluous to my question, but I think it might be illustrative.

The code above results in the following, which is unsatisfactory:

I don't know if I need to give any example data, but I gave it a shot here :

I managed to solve it quite neatly with the following:

tscale(range(21975 22464)) ttick() tmtick() tline() tmlab(21975 "mar" 22006 "apr" 22036 "maj" 22067 "jun" 22097 "jul" 22128 "aug" 22159 "sep" 22189 "okt" 22220 "nov" 22250 "dec" 22281 "jan " 22312 "feb" 22340 "mar" 22371 "apr" 22401 "maj" 22432 "jun" 22464 "jul" 22493 "aug" 22523 "sep" 22554 "okt" 22585 "nov" 22616 "dec" 22646 "jan " , angle(45) labsize(9pt) grid glcolor(gs15) glwidth(medthick)) tlab(22281 `" " " "  " "2021" "' 22646 `" " " " " "2022" "', labsize(2.9pt) grid glcolor(gs14) glwidth(medthick))
