[GitHub] [echarts] madlee opened a new issue #14236: Render tooltip with user defined functions.
madlee opened a new issue #14236:
URL: https://github.com/apache/echarts/issues/14236
### What problem does this feature solve?
I wish to show chemical structure / latex formula or some other complex content in a tooltip canvas.
I have the function (based on zrender) to draw these objects and I wish there is an API hooker to help me.
An extra AJAX request may be required to fetch the more data during the render.
### What does the proposed API look like?
```
tooltip: {
size: [150, 50], // The tooltip size prepared for render
onRender: function (
data, // The data of the selected point
render, // The echart/zrender object to draw on
boundRect // The bound rectangle to draw in
) {
axios.get("/some.api?id=" data["id"]).then(function (response) {
// Do some drawing code here.
})
}
}
```

Does [tooltip.formatter callback](https://echarts.apache.org/en/option.html#tooltip.formatter) work for you?
