The engine still picks a display prefix on its own. My kEUR data was shown as M (1,199 kEUR became 1.2), so ΔPL of about 50 kEUR rounds to 0.0 and the +96 kEUR total rounds to +0. Fix: set `measureScale: "_"` (no prefix) so kEUR values show as they are. - Item 3: the average overlay (`showOverlayAvg`). I will turn it off. - Items 4 and 5: the chart is too small and the grid rows are equal. I will give the chart 2/3 of the height, scale it up, and drop the chart title. The page header already names the measure. ### Step 1: `mcp__bino__validate_draft` ```json { "yaml": "apiVersion: bino.bi/v1alpha1\nkind: LayoutPage\nmetadata:\n name: sales_2025_page\nspec:\n pageLayout: custom-template\n pageCustomTemplate: '\"a a a\" \"a a a\" \"b b c\"'\n messageText: \"2025 revenue was slightly above plan (+96 kEUR, +0.4%): South (+329 kEUR) and Export (+167 kEUR) offset East (-411 kEUR, -11.4%)\"\n children:\n - kind: ChartTime\n spec:\n dataset: sales_2025_monthly\n measureScale: _\n showOverlayAvg: false\n showOverlayMedian: false\n scale: auto\n - kind: Table\n spec:\n dataset: sales_2025_region\n measureScale: _\n - kind: Text\n spec:\n value: x\n" } ```

### Agent No findings. The chart is now 873 x 377px (it was 585 x 316), and the table and text fill the bottom row. ### Step 11: `mcp__bino__validate_project` ```json { "execute_queries": true } ```
Result ``` {"diagnostics":[],"valid":true} ```
### Agent I made the changes and rebuilt. `get_layout_state` reports no findings and `validate_project` (with queries) passes. I can't see the rendered PDF, so items 1, 2, 4 and 6 are only fixed in theory until you check the labels. 1. **Units (and items 2 and 6, same cause):** the chart and table now have `measureScale: "_"` (no prefix). The engine had put its own M prefix on my kEUR data, so 1,199 kEUR showed as 1.2. That also turned a monthly ΔPL of about 50 kEUR into 0.0 and the +96 kEUR total into +0. Labels should now show kEUR, for example 1,199 per month, 4,944 for North and +96 in the total row. 2. **ΔPL row:** this was the same rounding problem. It should now show values like -54 or +53 kEUR. The bars stay short on purpose: they use the same scale as the revenue bars, as IBCS requires. 3. **"Ø AC" line:** that was the average overlay, which says nothing here. I removed it with `showOverlayAvg: false` (and `showOverlayMedian: false`). 4. **Overlaps:** I removed the chart title. The page header already names the measure and scenarios, so it was only crowding the legend. The chart is also 50% larger now (`scale: 1.5`), so the 12 ΔPL% labels have more room. `get_layout_state` does not check text overlap, so please confirm this one in the PDF. 5. **Space:** the grid gives the chart two of three rows and full width (`"a a a" "a a a" "b b c"`). The chart grew from 585 x 316 to 873 x 377px. To keep it inside the slot height I changed `unitScaling` from 250 to 350 kEUR/em on both the chart and the table, so they still share one scale. 7. **Wording:** the commentary now starts with "Slightly above plan." The title now reads "2025 revenue was slightly above plan (+96 kEUR, +0.4%): South (+329 kEUR) and Export (+167 kEUR) offset East (-411 kEUR, -11.4%)". **Engine limits and workarounds:** - **Variance bars:** with `measureScale: k`, the time chart scaled the bars but not the variance bars. My workaround is still in place: the DataSets return kEUR, and both components now use `measureScale: "_"`. - **No grow-to-fit:** `scale: auto` only shrinks a chart. It never makes it bigger to fill its slot, so I set a fixed factor (1.5). If the data range changes, this may need adjusting. - **Detail view still fails:** asking `get_layout_state` about a single component still fails with the same output-schema error. I read the region sizes from the error text instead. Only `pages/sales_2025_page.yaml` changed this round. ## Result - subtype: `success` - num_turns: `12` - duration_ms: `73169` - total_cost_usd: `2.222102` - is_error: `False`
