st: toway scatter plot with regression fit

[urbain thierry YOGO <yogout@gmail.com>]

Dear users

I have built a twoway scatter plot with regression fit using the
following command:

  twoway scatter mespvie mhealth , title("correlation between life
expectancy and health aid") xtitle("Health aid") ytitle("life
expectancy") mlabel(code) || lfit mespvie mhealth

But the graph does not display the coefficient of correlation. If
somebody know how to do to have this on the graph?. Thanks
