Echart怎麼把X軸反轉
阿新 • • 發佈：2018-11-25
具體實現程式碼如下 解決echarts 負軸，浮動負數，等的顯示
function chart_rkk(){
var rkkchart=echarts.init(document.getElementById('rkkDiv'));
var ageArea = [ '0~10','11~30','30~60','60~100','100以上'];
var FbarData = [3100, 2142, 1218, 581, 431]; //男
var MbarData = [-3010, -2742, -218, -381, -521]; //女
option = {
tooltip : {
trigger: 'axis',
axisPointer : { // 座標軸指示器，座標軸觸發有效
type : 'shadow' // 預設為直線，可選為：'line' | 'shadow'
},
formatter: function (params, ticket, callback) {
console.log(params)
var res = params[0].name ;
for (var i = 0, l = params.length; i < l; i++) {
res += '<br/>' + params[i].seriesName + ' : ' + Math.abs(params[i].value) ;
}
setTimeout(function () {
// 僅為了模擬非同步回撥
callback(ticket, res);
}, 500)
return 'loading...';
}
},
legend: {
data:[ '男', '女']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis : [
{
axisLabel : { formatter: function (value){return Math.abs(value);//顯示的數值都取絕對值
}
},
type : 'value'
}
],
yAxis : [
{
type : 'category',
axisTick : {show: false},
// data : ['0~5歲','5~10歲','10-30歲','30-50歲','50-70歲','70-100','100以上']
data : ageArea
}
],
series : [
{
name:'男',
type:'bar',
stack: '總量',
label: {
normal: {
show: true,
position: 'right',
}
},
// data:[320, 302, 341, 374, 390, 450, 420]
data:FbarData
},
{
name:'女',
type:'bar',
stack: '總量',
label: {
normal: {
show: true,
position: 'left',
formatter:function(v){return Math.abs(v.data)}
}
},
// data:[-120, -132, -101, -134, -190, -230, -210]
data:MbarData
}
]
};
rkkchart.setOption(option);
}
