@tyn1998 Thanks for the detailed plan. I have some questions about this:
If we consider drilling-down only, then all `groupId`s the data items should
be the same because typically we can only drill one thing down. But what
happens if there are different `groupId`s in the new option?
If I understand correctly, you want the developers to listen to all kinds of
click events and call `setOption` again like this, right?
```ts
chart.setOption(/* old option */);
chart.on('click', () => {
// check which item is clicked and find its children
chart.setOption(/* new option with its children */);
})
```
One problem is that, in this design, the developer has to consider about all
possible drilled down situations in the click callback and handle the
corresponding new option.
I think a better idea would be encapsulating the logic by ECharts like:
```ts
chart.setOption({
series: [{
// ...
data: [{
value: 10,
name: 'parent A',
drilldown: {
data: [{
value: 2,
name: 'first child of parent A'
}],
// other options for drilldown if you think is needed
}
}]
}]
});
```
So the developers don't have to think about drilling down at all. Apache
ECharts will update the chart just as it does with treemap drilldown right now.
That's my personal point of view. Let's also hear about what other mentors
think.
