st: rank ordered twoway graph

[Shehzad Ali <sia500@york.ac.uk>]

Hi listers,

I want to create a twoway graph (like spike or dropline) where the x-axis 
is a rank variable (based on say income) and y-axis is the other variable 
of interest (say health_pay). A simple command - twoway spike health_pay 
income - spread the x-axis over the whole range of income but I am 
interested in income rank and not income itself.

I know one way to do it is to generate income rank variable using - glcurve 
- and then plotting the rank_var against health_pay but I was wondering if 
there was a direct method.

Any help would be appreciated.

Thank you,

Shehzad
