Highcharts - Programmatically "flip" (reverse) Y Axis

All, I'm using Highcharts in a web app I'm working on. One of the requirements is that users should be able to click a button and 'flip' or reverse the Y axis. In other words - whe

Solution 1:

You can use the Axis.update() method:

$(function () {
    var chart = newHighcharts.Chart({
        chart: {
            renderTo: 'container'
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },
        yAxis: {
            reversed: false
        },
        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
        }]
   });

   var reversed = chart.options.yAxis.reversed;

   // the button action
   $('#button').click(function () {

       chart.yAxis[0].update({
           reversed: !reversed
       });  

       reversed = !reversed;
   });
});

Solution 2:

I don't think it's possible.

My advice is to destroy the chart using chart.destroy() and create the new one with the reversed property, like in this fiddle
