How to superimpose grid on a map

[Ali Rezaei]

Hello Everyone
I am trying to superimpose grid on my map in stata. I could not find proper way of doing that.
I also check GRMAP help however I could not find any option regarding grid.
this is my code
use RawData2011_2020.dta

grmap ETHANOLrp, t(18635) legtitle("fuel") fcolor(Reds2) clnumber(4) ocolor(Greys) clmethod(quantile) polygon(data(mp_shp.dta) ocolor(black))

I appreciate your insights ahead of time.

You can turn on the x&y scales and grids. Note - this places in grid under the map rather than superimposed on the map.

This example use Nick Cox's -mylabels- (ssc desc mylabels) for convenience

clear
use "italy-regionsdata.dta", clear
mylabels 38  58 78 98 115, myscale(10000*@) local(myxla)
mylabels 42  44.5 47 49.5 52, myscale(100000*@) local(myyla)
grmap relig1, xscale(on) xlabel(`myxla', grid) ylabel(`myyla', grid) yscale(on)

Thank you Scott,
it works for me.
Could you possibly let me know where I can find description of these option? I could not find xscale /xlabel in the GRMAP help file

Most twoway options can be passed to -grmap-. If you look under basemap_options it will list:

Y axis, X axis, Titles, Legend, Overall
twoway_options
