The underlying JavaScript code
var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,8,8,-5], axis:true});
function plotter() {
var t = board.algebra.geonext2JS(document.getElementById('input').value);
var f = new Function('x','var y = '+t+'; return y;');
board.create('functiongraph',[f]);
}
function clearAll(board) {
JXG.JSXGraph.freeBoard(board);
board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,8,8,-5], axis:true});
}
