URL: https://github.com/apache/echarts/issues/19764
### Version
5.5
### Link to Minimal Reproduction
-----
### Steps to Reproduce
initChart() {
let that = this;
//初始化X坐标轴
// let xValue = [];
// for (let i = 100; i < 900; i++) {
// xValue.push(i);
// }
const xValue = ['6', '6.5', '7', '7.5', '8', '8.5', '9', '9.5', '10'];
const yValue = ['6', '6.5', '7', '7.5', '8', '8.5', '9', '9.5', '10'];
//初始化Y坐标轴
// let yValue = [];
// for (let i = -26; i < 27; i++) {
// yValue.push(i);
// }
let option = {
xAxis: {
type: 'category',
data: xValue,
splitArea: {
show: true //斑马纹展示
}
},
yAxis: {
type: 'category',
data: yValue,
splitArea: {
show: true //斑马纹展示
}
},
title: {
top: 30,
left: 'center',
text: 'Daily Step Count'
},
tooltip: {},
visualMap: {
min: 0,
max: 10000,
type: 'piecewise',
orient: 'horizontal',
left: 'center',
top: 65
},
series: {
type: 'heatmap',
name: 'Znys Map',
data: that.seriesData,
}
};
option && that.myChart.setOption(option);
},
### Current Behavior
this.myChart = echarts.init(chartDom);
this.initChart();
let i = 1, j = 0
let data=[];
// this.timer = setInterval(function () {
for (let j = 0; j < 10; j++) {
let dataItem = [];
dataItem.push(j);
dataItem.push(i);
dataItem.push(8);
dataItem.push(i * 2);
// that.seriesData.push(dataItem);
data.push(dataItem);
// this.myChart.setOption({
// series: [{
// // 假设是某个系列
// data: data // 这里替换为你要添加的数据
// }]
// });
this.myChart.appendData({
seriesIndex: 0,
data: data
});
console.log('size is:'+this.seriesData.length)
}
### Expected Behavior
appendData有效
