The -if- condition needs to be applied globally.  Compare:

sysuse auto, clear

twoway scatter head mpg if fore == 1 || ///
line gear mpg if fore == 1, by(rep) name(gr1,replace)

twoway scatter head mpg || ///
 line gear mpg || ///
 if fore == 1, by(rep) name(gr2,replace)

Dear Statalist,

I have tried using the following code to produce an array of graphs for only the cases in a particular group.


twoway connected walkwano hourx if w3grp_1==1 || ///
  line medianrate hourx if w3grp_1==1, by(resid)

However, I get an array of graphs that includes blank graphs, for cases not in group 1.

I can call the file, select the cases and run without the if commands. That produces what I need. But I have to repeat that step multiple times in order to get separate arrays (which I want) for each cluster of cases.

I would like to use the "if" option successfully.

Can someone help?
Thank you.
