After using 5.3, use valueFormatter to display the data that is convenient to format and display series But when you need to do some folding and expansion display: as shown in the figure below, you need to display the summary of the data at the bottom of the tooltip.. The average value is formatted at the top of the tooltip to display the date, so you have to give up using valueFormatter and use the original formatter method <img width="393" alt="image" src="https://user-images.githubusercontent.com/5426866/204747098-c42ec56d-ac47-406c-953f-f751723f4b39.png";> ### What does the proposed API look like? I hope that some methods can be added to handle the display of the head and bottom tooltip: { trigger: 'axis', headerFormatter: header => `${new Date(header).toDateString()}`, valueFormatter: value => `${value.toFixed(2)}`, footerFormatter: params => { //do process calculate summary data } } </details> -- This is an automated message from the Apache Git Service.
