# plotting in a script file

I have install sage in my computer and i have started testing sage examples. I dont understand sth. for example

```
sage: v = [(1,10),(2,20)]
sage: line(v)
```

it runs in shell and I can look plot screen. I try below codes

```
sage: load "test.sage"
```

or

But instead of Interactive Shell, when I try to run the file "test.sage", on terminal :

```
$ sage test.sage
```

it isnt right.
