@cj20904,

Can you please share your OS details and Chromium version?

It looks like you are using an older version of CanvasJS. You can download the latest version of CanvasJS from here or use this CDN: https://cdn.canvasjs.com/canvasjs.min.js

Also, you forgot to render the chart in your jsfiddle.
