Highcharts contextButton color

highcharts, javascript

Solution

You need to change the theme node of the button. For example:

Full Example

    $(function () {
    $('#container').highcharts({

        chart: {
            backgroundColor: "white"
        },


        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },

        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]        
        }],

        exporting: {
            buttons: {
                contextButton: {
                    symbolStroke: "red",
                    theme: {
            fill:"gray"
        }
                }
            }
        }

    });
});

Problem

I want to custom Highchart's export button. I read on their doc that we can easily access to the buttons style with ` buttons: { contextButton: ... }` but it seems that I only can modify the symbol and I want to change the background color of the button too. Here is an example on JSFiddle. As we can see, the symbol's color can be changed with `symbolStroke` option but how can I change the background ?
