Drawing a tsset time graph with three y axis variables with different scales

[Aziz Essouaied]

Hello Stata community;

I have this little data:

* Example generated by -dataex-. To install: ssc install dataex
clear
input int Année long Effectif int(Impot_Total_Prlévé Moyenne_dimpot_par_capita)
2012 2622399 2620  999
2013 2573643 3125 1214
2014 2624140 3517 1340
2015 2700000 3549 1314
end
format %ty Année

As you can see, the first variable is a time variable, the other variables are quantitative ones with different scales.

Is there a possibility to draw one graph on which I could have the evolution of each of those quantitative variables with time, all on the same graph? I know I could use the "add a second y axis" option, but that only allows for two y axis.

Thanks for the help.

I suggest using multiline from SSC. You need to install it before you can use it:

ssc install multiline

* Example generated by -dataex-. To install: ssc install dataex
clear
input int Année long Effectif int(Impot_Total_Prlévé Moyenne_dimpot_par_capita)
2012 2622399 2620  999
2013 2573643 3125 1214
2014 2624140 3517 1340
2015 2700000 3549 1314
end
format %ty Année

multiline E I M A, recast(connected)

Here, recast(connected) is optional; any variable labels will be shown if defined; and you might consider xtitle("") on the grounds that any reader will know what 2012/2015 mean.

Nick Cox Thanks very much, that worked.
