HighCharts设置图表背景透明

其实就一句话：

 backgroundColor: 'rgba(0,0,0,0)'

完整示例：

 

$(function () {

        $('#container').highcharts({

            chart: {

                type: 'column',

                backgroundColor: 'rgba(0,0,0,0)'

            },

            title: {

                text: 'Stacked column chart'

            },

            xAxis: {

                categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']

            },

            yAxis: {

                min: 0,

                title: {

                    text: 'Total fruit consumption'

                },

                stackLabels: {

                    enabled: true,

                    style: {

                        fontWeight: 'bold',

                        color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'

                    }

                }

            },

            legend: {

                align: 'right',

                x: -70,

                verticalAlign: 'top',

                y: 20,

                floating: true,

                backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',

                borderColor: '#CCC',

                borderWidth: 1,

                shadow: false

            },

            tooltip: {

                formatter: function() {

                    return '<b>'+ this.x +'</b><br/>'+

                        this.series.name +': '+ this.y +'<br/>'+

                        'Total: '+ this.point.stackTotal;

                }

            },

            plotOptions: {

                column: {

                    stacking: 'normal',

                    dataLabels: {

                        enabled: true,

                        color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'

                    }

                }

            },

            series: [{

                name: 'John',

                data: [5, 3, 4, 7, 2]

            }, {

                name: 'Jane',

                data: [2, 2, 3, 2, 1]

            }, {

                name: 'Joe',

                data: [3, 4, 4, 2, 5]

            }]

        });

    });

    

 

还有另外一个属性，plotBackgroundColor: null

这个属性的意思是指图表部分，不含标题、说明信息，x轴y轴上的提示信息等部分的背景色，例如：
