JQuery – Sparkline: Re-draw on resize / responsive sparklines

I’ve been suckered in by the awesome JQuery Sparkline plugin – I won’t go over how it works or what it does, but rather a quick ‘fix’ for fixing issues with how the output deals with browser resizing. (Long story short, it doesn’t by default).

Here’s a visual of the issue I’m talking about with responsive/resizing layouts



After resize:


The fix:

Assign your Sparkline initialization to a variable as a function.

Then call the function to intialize, and bind it to JQuery’s $.resize() method.

I also used a short setTimeout() to avoid excessive redrawing during the resize operation.

And voila!

    Thanks – just what I was looking for!

    Your usage of setTimeout is not stopping the excessive redraw of sparklines, just delays it.

    You need to use clearTimeout as well:

    $(function() {

    var sparklineLogin = function() {
    [ pointData ],
    type: 'line',
    width: '100%',
    height: '25'

    var refreshSparklines;
    $(window).resize(function(e) {
    refreshSparklines = setTimeout(sparklineLogin, 500);

    • styu: You’re absolutely right – good catch.I had dealt with that issue in my project and never updated the post.

      I’ve updated the example; thanks for the feedback.

    Thank you so much! Just saved me a bunch of time figuring this out!

  4. Actually a simpler solution is to refer to the canvas within the sparkline and resize it to 100% on the event:

    $(window).resize(function(e) {
    $(‘.adv-login-sparkline canvas’).css(“width”,”100%”);

    Specially if you are using the text in the html, otherwise when you redraw it won’t have any values for the sparkline
