Depending on the value of the slider `s`, one of the curves is highlighted.
// Define the id of your board in BOARDID
const board = JXG.JSXGraph.initBoard(BOARDID, {boundingbox: [-10, 10, 10, -10]});
// Slider
var s = board.create('slider', [[1,8],[5,8],[0,0,1]]);
// If s < 0.5: red and thick, else blue and thin
var g = board.create('functiongraph', [(x) => x*x], {
strokeColor: () => (s.Value() < 0.5) ? 'red' : 'blue',
strokeWidth: () => (s.Value() < 0.5) ? 4 : 1
});
// If s >= 0.5: red and thick, else blue and thin
var f = board.create('functiongraph', [(x) => x + 1], {
strokeColor: () => (s.Value() >= 0.5) ? 'red' : 'blue',
strokeWidth: () => (s.Value() >= 0.5) ? 4 : 1
});
