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]]. | |||

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]);
