Stata 9 - multiple plots on a scatter graph

[Alicia Woods]

I'm trying to create a scatter plot graph that includes 3 different plots. I cannot find the commands or the option in the GUI interface of Stata 9 to do so. Can someone provide some advice on the command structure or the where to find this option in the GUI interface of Stata9? My multiple plots are created using "if" statements, but this would be a lot easier if i could find the option of just creating separate plots in the GUI interface and then include the if statements there.

This is what I've tried so far.....

graph twoway (lfitci trees elevation)(scatter trees elevation) if heightcatnum==1) (lfitci trees elevation)(scatter trees elevation) if heightcatnum==2 (lfitci trees elevation)(scatter trees elevation) if heightcatnum==3, ytitle(Average Percent Cover) xtitle(Elevation (m))

Thanks in advance.

I don't know anything about the menus to advise if that is what you are asking.

In any version of Stata since 8, you might start with something more like

separate trees, by(heightcatnum) veryshortlabel
twoway scatter trees? elevation, legend(order(1 "1" 2 "2" 3 "3"))

Good luck on adding three regression lines and confidence intervals to that without making a complete mess. But why not

twoway lfitci trees elevation || scatter trees elevation, by(heightcatnum)
