Hi, This is because the Wechat application doesn't support creating a DOM element. So you need to use rich text of ECharts to render tooltips with Canvas. Please follow the document to see more details and examples: https://github.com/ecomfe/echarts-for-weixin?tab=readme-ov-file#%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8-tooltip
