小技巧，echarts的tooltip显示多值
最近研究echarts，有些小技巧还是需要琢磨的，给自己做一个备忘。
通过修改series的data数据的value，在tooltip里重新formatter一下data，再用html拼接一下
前：
myChart.showLoading();
$.get(ROOT_PATH + 'data/asset/geo/USA.json', function (usaJson) {
myChart.hideLoading();
echarts.registerMap('USA', usaJson, {
Alaska: { // 把阿拉斯加移到美国主大陆左下方
left: -131,
top: 25,
width: 15
},
Hawaii: {
left: -110, // 夏威夷
top: 28,
width: 5
},
'Puerto Rico': { // 波多黎各
left: -76,
top: 26,
width: 2
}
});
option = {
title: {
text: 'USA Population Estimates (2012)',
subtext: 'Data from www.census.gov',
sublink: 'http://www.census.gov/popest/data/datasets.html',
left: 'right'
},
tooltip: {
trigger: 'item',
showDelay: 0,
transitionDuration: 0.2,
formatter: function (params) {
var value = (params.value + '').split('.');
value = value[0].replace(/(\d{1,3})(?=(?:\d{3})+(?!\d))/g, '$1,');
return params.seriesName + '
' + params.name + ': ' + value;
}
},
visualMap: {
left: 'right',
min: 500000,
max: 38000000,
inRange: {
color: ['#313695', '#4575b4', '#74add1', '#abd9e9', '#e0f3f8', '#ffffbf', '#fee090', '#fdae61', '#f46d43', '#d73027', '#a50026']
},
text: ['High', 'Low'], // 文本，默认为数值文本
calculable: true
},
toolbox: {
show: true,
//orient: 'vertical',
left: 'left',
top: 'top',
feature: {
dataView: {readOnly: false},
restore: {},
saveAsImage: {}
}
},
series: [
{
name: 'USA PopEstimates',
type: 'map',
roam: true,
map: 'USA',
emphasis: {
label: {
show: true
}
},
// 文本位置修正
textFixed: {
Alaska: [20, -20]
},

myChart.setOption(option);
