highcharts - 如何在图例下的图例底部中心和图表底部中心添加文本？

Question

我有一个自定义的 HighCharts，图例中有总数。我需要在“图例中”的总数下添加一行自定义文本。此外，我需要在图表底部的“图例下”添加文本中心。

见 fiddle :

我确实弄清楚了这一点，但不知道如何使文本以图例为中心。

spacingBottom是您需要添加的内容，并且您还需要处理偏移量:

chart: {
            events: {
                load: function () {
                    var label = this.renderer.label("How do I move this center and under the legend.")
                    .css({
                        width: '450px',
                        color: '#222',
                        fontSize: '16px'
                    })
                    .attr({
                        'stroke': 'silver',
                        'stroke-width': 2,
                        'r': 5,
                        'padding': 10
                    })
                    .add();

                    label.align(Highcharts.extend(label.getBBox(), {
                        align: 'center',
                        x: 0, // offset
                        verticalAlign: 'bottom',
                        y: 50 // set the right offset
                    }), null, 'spacingBox');

                }
            },
            renderTo: 'container_chartFreqAtaTailNum',  
            type: 'bar',
            height: 895,
            spacingBottom: 100 // The space between the bottom edge of the chart and the content (plot area, axis title and labels, title, subtitle or legend in top position).         
        }
