Question

echart散点图问题：如何在散点图中特别标出某一个特定的点，如[120,70]

option = {
title : {
text: '指标分布',
subtext: '虚拟数据'
},
tooltip : {
trigger: 'axis',
showDelay : 0,
axisPointer:{
show: true,
type : 'cross',
lineStyle: {
type : 'dashed',
width : 1
}
}
},
legend: {
data:['XX']
},
toolbox: {
show : true,
feature : {
mark : {show: true},
dataZoom : {show: true},
dataView : {show: true, readOnly: false},
restore : {show: true},
saveAsImage : {show: true}
}
},
xAxis : [
{
type : 'value',
scale:true,
axisLabel : {
formatter: '{value}'
}
}
],
yAxis : [
{
type : 'value',
scale:true,
axisLabel : {
formatter: '{value}'
}
}
],

series : [
{
name:'XXX',
type:'scatter',
data: [[120, 70], [112, 69], [138, 78], [112, 86], [125, 86],
[133, 76], [116, 90], [126, 72], [109, 67], [134, 79],
[117, 70], [109, 82], [125, 75], [134, 102], [143, 90],
[113, 76], [121, 84], [110, 73], [111, 69], [108, 68],
[106, 70], [104, 66], [103, 71], [106, 65], [112, 80]
],
markPoint : {
data : [
{type : 'max', name: '最大值'},
{type : 'min', name: '最小值'},
]
}
}
]

Answer 1

试试添加：
markPoint: {
data: [
{
name: '某个坐标',
coord: [120, 70]
}
]
},
