Thread: plotting different series in one graph

hi ,

I am trying to plot different lorenz curves ( with different percentage bases ) in a single graph...the x-axis represents the percentage cumuilative number of firms and the y axis represents the percentage cumulative output.

if i have 20 firms, then the x-axis will be 1/20 , 2/20....20/20 ->( 0,5%,10%...100%)

if i have 19 firms, then the x-axis will be 1/19, 2/19...19/19 ...evidently this is differnet from the one above...how can i plot both in one graph?...or can't i?

thx for any help!

...thats not the problem...i can get the line of equality but the problem is plotting series with different percentage cumulative output against firm
