[I] [Feature] I hope to get all series information when tooltip.trigger = item [echarts]
li-jia-nan opened a new issue, #20579:
URL: https://github.com/apache/echarts/issues/20579
### What problem does this feature solve?
`tooltip.formatter` 方法接受一个 `params` 参数，当 `tooltip.trigger = item` 的，`params` 是当前 hover 的 series data，当 `tooltip.trigger = axis` 时，`params` 是一个数组，包含所有的 series data
我需要在 `tooltip.trigger = item` 的时候，在 tooltip 中也展示所有的 series 信息，所以我希望 `tooltip.trigger = item` 的，也可以获取到所有的 series data
---
The `tooltip.formatter` method accepts a params. When `tooltip.trigger = item`, `params` is the series data of the current hover. When `tooltip.trigger = axis`, `params` is an array containing all series data.
I need to display all series info in the tooltip when `tooltip.trigger = item`, so I hope to get all series data when `tooltip.trigger = item`.
### What does the proposed API look like?
当 `trigger = 'item'` 时可以新增一个 context 参数：
```ts
tooltip: {
trigger: 'item',
formatter: (params, context) => {
console.log(context);
}
}
```

The `getOption` API is expensive and it's not first recommended. Except for this, I think there is no public API to get such information, but I still post a [workaround](https://echarts.apache.org/examples/editor.html?c=line-simple&code=PYBwLglsB2AEC8sDeAoWtJgDYFMBcya6GOAHmAQOQC2ArlpLADITQ6VEC-ANEWMMAYQQBVMQwAnCAHNpOCVQhgc1Sr3EAzYBOoBDMMoWwAFCF0Td1AM4BKBAD5C49AGMYVsLCvyIOKwFlgABMcLARYagBPAGEAC3MwImdYADo5MECQrGMbJOcAenzYF3joOS8fPwBJaBDSWAgNWEjgWlgAd11oT35YdNhgMFj5Cqk_BugtHX0oaDzxQoGJWFpvDGHYAAMcXRKAZUqrTdgNWmgXSBgMYAbDfRxYXSww7zGreeJFgCNaTxBcXRraCDCAuB5DB6bdKZULHACCAAUqg0rLBgX9aF8sKCTto0cB2h90ItVg8lBNYCAJMFaBdZrAcNAAG4QanURmeFzmHCnZ6RImpdIHN4AIUiNTqpnMlisKVevisErINgA3B83NArIIcCksMBpMZKPLxqwtGpRgqYVgUqBLtBVer3J4pnoDCNEABtAWbFy0CQSDmwIL6XQEAAkSDMFmsKWDYF0nE26mSW19_sDcd0StI4cj0pjmezieTyU2xtRmdz5atNvAs1jIcTHwAumrkgGwH64C79IYUgArYCsQ0AHi-EnslAd4k4XGTuDktVEeUrsA9lAAonoIFhzZQAKrQelwoJWPcANQgIRuJ7P3FglAAIqycBc9wdzCVYBuyqx2M25yIaQpCCZdxFwDQKAfABmABSNQ8ikaRYigygABZ4JLWAvkGfhqCoOCEPEDV41YJhdC
