好吧,但是应该在哪里显示这些信息?
我准备了简单的示例,在工具提示和图表下方的报告 div 中标记了此信息。
http://jsfiddle.net/sbochan/8sKcs/
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
},
yAxis: {
min: 0,
max:4000,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
formatter: function() {
if(this.y > (this.series.chart.yAxis[0].max))
return this.series.name +': '+ this.y + ' max is smaller: '+this.series.chart.yAxis[0].max ;
else
return this.series.name +': '+ this.y;
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
credits: {
enabled: false
},
series: [{
name: 'Year 2008',
data: [973, 914, 4054, 732, 34]
}]
},function(chart){
var max = chart.yAxis[0].max,
content = '<h2>Points</h2><br/>';
$.each(chart.series,function(i,serie){
$.each(serie.data,function(j,data){
if(data.y > max)
content += 'Point: '+data.y+' is bigger than max: '+max;
});
});
$('#report').html(content);
});
});
});
编辑:
您还可以添加
data.graphic.attr({
fill:'yellow'
});
更改条的颜色。
