This is an example for a step function realized as function graph. The steps are not drawn. JSXGraph has its own element "stepfunction", where the steps are visible, see Step function II.

### The underlying JavaScript code

```
var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,8,8,-5], axis:true});
var f = function(x) {
if(x<0)
return -1;
if(x>=0 && x <2)
return 1;
if(x>=2)
return 2;
}
board.create('functiongraph',[f]);
```
