The documentation for Sage plotting in 2 dimensions is here. From your description, I think you are talking about region_plot(). Here's an example:

```
x,y = var('x,y')
region_plot([x^2 + y < 1, x < y], (x,-2,2), (y,-2,2))
```

The region plotted consists of the points satisfying both inequalities (intersection), where x is in the interval [-2,2] and y is in the interval [-2,2].

I am not sure about your question, but you can do:

```
sage: line2d([(0,0),(1,0)], xmin=-2, xmax=2, thickness=2)
```

sorry I have not described my question good enough. I'm looking for something like: plot all points (x,y) for which x is in interval A and y is interval B. I would like to define a set of Points (x,y) by some rules, maybe do some set operations like intersection on it, and finally plot it.
