-glcurve- available from the Stata Journal website or the SSC archive will do that.
To order your observations in descending order (rather than the default ascending order), you can use the -sortvar()- option:
ssc install glcurve
glcurve var , lorenz
gen minvar = 0-var
glcurve var , sortvar(minvar) lorenz
read the help file for -glcurve- to find out about options for saving curve coordinates for later customizing the resulting plot or combining curves.
Good luck
