URL: https://github.com/apache/superset/pull/37188
### SUMMARY
Add `stacked` field to XYChartConfig schema in the MCP service that enables
stacking bars/areas on top of each other instead of displaying them
side-by-side.
**Changes:**
- Added `stacked: bool` field to `XYChartConfig` in `schemas.py` (default:
`False`)
- Updated `map_xy_config()` in `chart_utils.py` to set `form_data["stack"] =
"Stack"` when `stacked=True`
This allows LLM clients using the MCP service to create stacked bar and area
charts by simply setting `stacked: true` in the chart configuration.
**Example usage:**
```json
{
"dataset_id": 123,
"config": {
"chart_type": "xy",
"x": {"name": "month"},
"y": [{"name": "revenue", "aggregate": "SUM"}],
"group_by": {"name": "product_line"},
"kind": "bar",
"stacked": true
}
}
```
### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
N/A - This is a schema/API enhancement, no UI changes.
### TESTING INSTRUCTIONS
1. Start the MCP service
2. Use `generate_chart` or `update_chart` tool with `stacked: true` in the
XY chart config
3. Verify the resulting chart displays bars/areas stacked instead of
side-by-side
