堆疊圖是ECharts中使用的一種常見類型，可以方便地展示數(shù)據(jù)的堆疊情況。在使用ECharts繪制堆疊圖時(shí)，需要使用JSON格式的數(shù)據(jù)來進(jìn)行配置。以下是一段使用JSON格式配置ECharts堆疊圖的示例代碼：

{
"title": {
"text": "ECharts堆疊圖示例",
"subtext": "堆疊圖",
"left": "center"
},
"tooltip": {
"trigger": "axis",
"axisPointer": {
"type": "cross",
"crossStyle": {
"color": "#999"
}
}
},
"legend": {
"data":["數(shù)據(jù)1","數(shù)據(jù)2","數(shù)據(jù)3","數(shù)據(jù)4"],
"top":"20"
},
"grid": {
"left": "3%",
"right": "4%",
"bottom": "3%",
"containLabel": true
},
"xAxis" : [
{
"type" : "category",
"boundaryGap" : false,
"data" : ["周一","周二","周三","周四","周五","周六","周日"]
}
],
"yAxis" : [
{
"type" : "value"
}
],
"series" : [
{
"name":"數(shù)據(jù)1",
"type":"line",
"stack": "堆疊1",
"data":[120, 132, 101, 134, 90, 230, 210]
},
{
"name":"數(shù)據(jù)2",
"type":"line",
"stack": "堆疊1",
"data":[220, 182, 191, 234, 290, 330, 310]
},
{
"name":"數(shù)據(jù)3",
"type":"line",
"stack": "堆疊2",
"data":[150, 232, 201, 154, 190, 330, 410]
},
{
"name":"數(shù)據(jù)4",
"type":"line",
"stack": "堆疊2",
"data":[320, 332, 301, 334, 390, 330, 320]
}
]
}

在上述代碼中，title表示堆疊圖的標(biāo)題，tooltip設(shè)置了交互提示框的相關(guān)參數(shù)，legend設(shè)置了數(shù)據(jù)系列的名稱，grid則是設(shè)置了圖表的坐標(biāo)系。xAxis和yAxis則分別設(shè)置了x軸和y軸的類型和數(shù)據(jù)。最后，series表示各個(gè)數(shù)據(jù)系列的相關(guān)信息，包括名稱、類型、堆疊方式和數(shù)據(jù)。
