我试图在highcharts气泡图工具提示中显示更多数据但没有成功。如何在工具提示格式化程序中访问this.point.com?
我使用的气泡图将日期时间设为x轴。
$('#chart-bubble').highcharts({
chart: {
type: 'bubble',
zoomType: 'xy',
plotBorderWidth: 1
},
title: {
text: 'Risk & Profit Vs Date'
},
tooltip: {
useHTML: true,
formatter: function(){
var expectedProfit = '';
if( this.point.z !== 'none' )
{
expectedProfit = formatExpectedProfit(this.point.z);
}
var tooltip = '<table class="table table-bordered" style="width: 300px;"><tbody><tr><td colspan="2"><h5>'+this.series.name.substr(0,75)+'...</h5></td></tr>' +
'<tr><td>Risk:</td><td>'+this.y+'</td></tr>';
if( expectedProfit !== '' )
{
tooltip += '<tr><td>Profit:</td><td>'+expectedProfit+'</td></tr>';
}
else
{
tooltip += '<tr><td>Comments:</td><td>'+this.point.comments+'</td></tr>';
}
tooltip += '</tbody></table>';
return tooltip;
},
followPointer: false
},
rangeSelector: {
enabled:true
},
xAxis:{
type: 'datetime',
dateTimeLabelFormats: {
day: '%e of %b'
}
},
yAxis: {
title: {
text: 'Ri'
}
},
series: prepareData(res.bubble)
});
这是prepareData函数:
function prepareData(data)
{
for( var i in data )
{
var item = data[i];
for( var k in item.data )
{
var itemData = item.data[k];
if( itemData[0] )
{
var split = itemData[0].split("-");
var y = split[0];
var m = split[1]-1;
var d = split[2];
itemData[0] = Date.UTC(y,m,d);
item.data[k] = itemData;
}
}
data[i] = item;
}
return data;
}
res.bubble json从PHP返回:
$list = array();
$list[] = array('name'=>'project 1','color'=>'#FF0000','data'=>array(new \DateTime(),20,'none'),'pointInterval'=>86400000,'comments'=>'this is a comment');
// ....通过向此数组添加更多元素来重复

您可以通过point.options[/* property */
访问所有其他媒体资源。
Highcharts.chart('container', {
chart: {
type: 'bubble',
},
tooltip: {
formatter: function () {
return this.point.options.comments[0];
}
},
series: [{
data: [
{ x: 95, y: 95, z: 13.8, name: 'BE', comments: ['this is a comment'] },
]
}]
});
