折线图等canvas转成图片,echarts api方法 getDataURL(),好像在taro里没法使用,有没有提供相应方法?

暂时按以下方式处理的:
nextTick(async () => {
const echartsInstance = await classRatioChangeChartsRefs.value[index].refresh(option)
setTimeout(() => {
wx.canvasToTempFilePath(
{
canvas: echartsInstance._dom.canvasNode,
quality: 1,
},
instance, // const instance = getCurrentInstance()
)
.then((res) => {
classRatioChangeChartsImg.value[index] = res.tempFilePath
})
.catch(console.log)
}, 1000)
})
