Create a chart with 2 y axes, each with a different number format 2. Create a tooltip with `trigger: 'axis'` 3. Attempt to format each number in the tooltip in the same way as each number's corresponding axis ### Current Behavior I can access information about the data using `params`, but this does not include the `yAxisIndex`. Without `yAxisIndex`, I am not able to determine which format to apply to the numbers in the tooltip. ### Expected Behavior `params` should include at least `yAxisIndex` since it is a property of the series which is being summarized in the `params`. Even though with `trigger: 'axis'`, you don't know which series is currently active (i.e. they are all active at once), this information can still be contained in `params` since it can be used to execute iterative logic over the information within `params`. Alternatively, if there is a way to pass arbitrary information which will appear in `params`, that would solve my problem (e.g., if I could pass a custom column into the series config and retrieve it in the tooltip formatter function through `params`). ### Environment ```markdown N/A ``` ### Any additional comments? The reason I need to figure this out with `trigger: 'axis'` is that tooltips are not really usable with `trigger: 'item'`. Ideally, I could use trigger item to get tooltips displayed for individual series in a chart, but the target hover area is unreasonably small since it relies on symbols, and I typically leave symbols out of my charts for cleanliness of appearance. The only way around this seems to be a custom setup using events, which I would prefer not to do. -- This is an automated message from the Apache Git Service.
