@Ovilia When asynchronous data is set dynamically, does it make a
difference if setOption sets other static data again? Example: Performance
Dynamically updating data ，Is there a difference between the two approaches?
1、myChart.setOption({
title: {
text: '异步数据加载示例'
},
tooltip: {},
legend: {},
xAxis: {
data: data.categories
},
yAxis: {},
series: [
{
name: '销量',
type: 'bar',
data: data.values
}
]
});
2、
myChart.setOption({
xAxis: {
data: data.categories
},
series: [
{
// 根据名字对应到相应的系列
name: '销量',
data: data.data
}
]
});
