If you are trying to make the chart fill the container (and use that for sizing) you need maintainAspectRatio = false in conjunction with responsive = true
var ctx = document.getElementById("canvas").getContext("2d");
var myLine1 = new Chart(ctx).Line(lineChartData1, {
maintainAspectRatio: false,
responsive: true
});
Your canvas height and width won’t be respected in this case.
