Jagath wants to draw a scatter diagram with a trend line on it
-------------------------------------------

You can combine two or more plots in a single graph. Try this:

    clear
    sysuse auto.dta
    twoway (scatter mpg weight)(lfit mpg weight)

This gives the linear regression estimate. A smooth Lowess curve is
drawn by:

    twoway (scatter mpg weight)(lowess mpg weight)

Hope this helps
Svend
