A long time ago (four, five years?) I had the same problem.
The solution presented to me (by Bill Gould, by Nick Cox?), which I still use, was (for my data):

```. program define wander

1. gph open
2. ltable  anos censura [freq=numero] if origem==0,graph  interval(0,1,2,3,4,
```
```5,6,7,8,9,10,11,12)xlabel(0,1,2,3,4,5,6,7,8,9,10,11,12)xline(0,2,4,6,8,10,12)
ylabel(0,.2,.4,.6,.8,1)yline(0,.2,.4,.6,.8,1) pen(2) noconf notab t1(azul=par
ticular/vermelho=IAPC)
```
```  3. ltable  anos censura [freq=numero] if origem==1,graph  interval(0,1,2,3,4,
```
```5,6,7,8,9,10,11,12)xlabel(0,1,2,3,4,5,6,7,8,9,10,11,12)xline(0,2,4,6,8,10,12)
ylabel(0,.2,.4,.6,.8,1)yline(0,.2,.4,.6,.8,1) pen(3) noconf notab t1(azul=par
ticular/vermelho=IAPC)
```
```  4. gph close
5. end

. wander
```
```

Here's a silly example of how to use -plot()-.
```r so I guess.
```

Another handle which would be useful is for -ltable- to generate as variables the quantities it tabulates; then you could knit your own graph.

```Dear Nick:
could you show how to do this other handle?

```

Has anyone had experience using the -plot- function with -ltable-?
To be specific:
. ltable time censor, graph by(treat)
works fine and it gives me two graphs side by side, each with a single
line--treat takes on two values: 0 & 1.
What I want is the two lines on a *single* graph.
