Set height of chart in Chart.js
If you disable the maintain aspect ratio in options then it uses the available height:
var chart = new Chart('blabla', { type: 'bar', data: { }, options: { maintainAspectRatio: false, } });
The easiest way is to create a container for the canvas and set its height:
<div style="height: 300px"> <canvas id="chart"></canvas></div>and set
options: { responsive: true, maintainAspectRatio: false}
Seems like var ctx = $('#myChart'); is returning a list of elements. You would need to reference the first by using ctx[0].Also height is a property, not a function.
I did it this way in my code:
var chartEl = document.getElementById("myChart");chartEl.height = 500;
