Dear all,
I tried estimating Lorenz curve with the command

Lorenz HHEXP

follow by
Lorenz graph

for the graph. But the following error message kept occuring:
axis.new: class member function not found
(error occurred while loading twowaygraph_g.class)
twowaygraph_g.new (pci 0 0 1 100, lstyle(yxline)) (rarea __000008 __000009 __000005, pstyle(ci)) (line
__000004 __000005, pstyle(p1line)) in 1/21, xtitle("population percentage") ytitle("cumulative outcome
proportion") legend(order(3 2 "95% CI")): class member function not found

twoway is not a valid graph subcommand
error executing lorenz graph

Can anyone help out on this?

Thank you.

Saheed.
