echarts鼠标移入柱状图，上方数值闪烁消失

根据引用中的描述，鼠标移入柱状图时，上方数值闪烁消失的问题可以通过在echarts的配置项setOption中增加第二个参数为true来解决。示例代码如下：

let option: EChartsOption = {
xAxis: {
type: "category",
data: xAxis.value
},
yAxis: {
type: "value"
},
series: [
{
data: series.value,
type: "bar",
barWidth: 30,
label: {
show: true,
position: "top"
}
}
]
};

myChart.value.setOption(option, true);

通过设置第二个参数为true，图表将会在更新数据时保留之前的动画效果，从而解决数值闪烁消失的问题。<em>1</em><em>2</em><em>3</em>
