Example page how to use the LineChart.
LineChart (shouldFill = true)
// Define a dataset.
var dataset = {

'myThirdDataset': [[0, 0.46], [1, 1.45], [2, 1.0], [3, 1.6]],
'myFourthDataset': [[0, 0.3], [1, 0.83], [2, 0.7], [3, 0.2]]

// Define options.
var options = {
// Define a padding for the canvas node
padding: {left: 30, right: 0, top: 10, bottom: 30},

// Set the labels.
xTicks: [

// Instantiate a new LineCart.
var line = new Plotr.LineChart('lines1',options);
// Add a dataset to it.
line.addDataset(dataset);
// Render it.
line.render();
LineChart (shouldFill = false)
// Instead of instantiating a new LineChart object,
// you also can use reset(), that resets the options and datasets.
line.reset();
// Change some attributes.
