Hi guys,,,

I just wanted to know how to plot two curves from the same dataset on the same graph.

this code has to plot only one curve for prot_percent, I wanna to plot fat_percent on the same graph, and all the data on the same dataset. (may dataset name is fit).

best regards

Ibrahim

It may be time to use the newer SG graphics procedures. SGPLOT makes it fairly easy to create multiple plots as you request as long as the x axis use the same variable.

proc sgplot data=fit;
title1' Lactation curves of milk fat and milk protein % ';
   series y=pred x=time;
   series y=TEST_DAY_PROT_PERCENT x=time;
   series y=Fat_PERCENT x=time;
run;

Lots of appearance options related to markers and colors to control

Use SCATTER instead of SERIES if you want points instead of connected points.
