Mixed content error

[koustabhdolui]

When I insert my API key, this error shows up on the console.

jquery.min.js:6 Mixed Content: The page at 'https://koustabhdolui.github.io/channel-viz/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://api.xively.com/v2/feeds/61916.json?_=1506607057936'. This request has been blocked; the content must be served over HTTPS.

I went ahead and changed the variable n=http to n=https://api.xively.com in channel-viz/js/xivelyjs-1.0.0.min.js but the error still persists. Is there a different variable that must be changed?
