### Steps to Reproduce
1. See reproduction link
2. See reproduction link
3. None
### Current Behavior
When having a series with a time based x-axis, 'coord' mark points values are undefined. Using a type 'max' markPoint, the value is shown. Using a formatter with the 'coord' markPoint, {c} is shown as undefined.
### Expected Behavior
The value of the 'coord' markPoint should be shown just like with the 'max' type markPoint
### Environment
```markdown
- OS:win 11
- Browser: chrome
- Framework: -
```

Still reproduces in ECharts v6.1.0 (2026-10-20, Chromium 151):
1. Create a line chart with a time x-axis.
2. Add a `markPoint` defined by `coord: ['2024-03-01', 198]` with `label.formatter: '{c}'`.
3. The pin label renders as `undefined` instead of `198`.
4. Same chart with `label.formatter: p => p.data.coord[1]` renders `198` correctly.
The `{c}` template variable is not populated for coord-based markPoints on a time axis — `params.value` is `undefined`; `data.coord[1]` is correctly set. Workaround: use the function form.

yes, value is not set for ```format:'{c}'``` - it's a **bug**.
workaround is to use ```formatter: x => {return x.data.coord[1];}```
