如何在图例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，在图例中有总计。我需要添加一行自定义文本，其中心位于“图例”中的总计中。另外，我需要在图表底部“图例下”添加文本中心。

[编辑] 我确实想到了这个，但不知道如何让文字以传说为中心。 http://jsfiddle.net/no1uknow/cvsTB/1/

$(function () {
    var chart; 
    $(document).ready(function() {



        var container_chartFreqAtaTailNum = new Highcharts.Chart({

spacingBottom是您需要添加的内容，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).         
        }
