What does the proposed API look like?

这里显示的值想要 formatter 格式化为不同格式，但是只有 tooltip.formatter 拼接整个 html，但是一般情况下只需要修改值的格式，不需要改其他内容，想要实现如下 API

        tooltip: {
            formatter: data => {
                return { name: data.type, value: `${data.value}%` };
            },
        },

What does the proposed API look like?

The values shown here want formatter formatted to be formatted in different formats, but only tooltip.formatter stitches the entire html, but in general only need to modify the format of the value, do not need to change anything else, want to implement the following API

        tooltip: {
            formatter: data => {
                return { name: data.type, value: `${data.value}%` };
            },
        },
