420-443: State mutation insidesetStatecallback.The pattern of mutating
tooltipFocusbefore returning a newSet(e.g., line 424tooltipFocus.add(dataKey)) works but is an anti-pattern that could cause issues with React's concurrent features.Consider creating a new Set from scratch:
const onTooltipFocus = (e: ChartMouseEvent) => { const dataKey = e.tooltipPayload[0].dataKey if (!tooltipFocus.has(dataKey)) setTooltipFocus((tooltipFocus) => { - tooltipFocus.add(dataKey) - return new Set(tooltipFocus) + return new Set([...tooltipFocus, dataKey]) }) }
31-395: Consider extracting helper functions outside the component.The
buildChartDataAndLegendfunction is ~360 lines and defined at module scope, which is good. The nested helper functionsaddFertilizerApplicationandaddCultivation(lines 168-236) could be extracted to improve testability.

Learning: In the fdm project, fdm-calculator integration for new features like b_lu_variety is handled in separate updates from the core data model changes. When fdm-core functions are updated to support new fields, fdm-calculator can consume these enhanced APIs without requiring changes in the same PR that introduces the core functionality.

Learning: In the organic matter balance chart (fdm-app), degradation values are multiplied by -1 before plotting to show supply and degradation bars side-by-side with positive magnitudes, enabling direct visual comparison.

Learning: In the nitrogen balance calculation system (fdm-calculator), removal and volatilization values are negative by definition.

Learning: In nitrogen balance calculations for agricultural systems, removal and volatilization are calculated as negative values by definition since they represent nitrogen losses from the system. The balance calculation uses addition (.add()) for all components because removal and volatilization are already negative, so adding them effectively subtracts the losses from the supply.

1-5: LGTM!The changeset correctly documents the minor version bump for the calculator package, and the description accurately summarizes the data shape unification and new breakdown capabilities.
fdm-app/app/routes/farm.$b_id_farm.$calendar.balance.nitrogen._index.tsx (4)
263-263: LGTM!The access pattern correctly updated to use the nested
supply.totalproperty, aligning with the new structured data shape from the calculator.
279-279: LGTM!Correctly accessing
removal.totalfrom the nested structure.
295-298: LGTM!Properly accesses the nested
emission.ammonia.totalpath. Based on learnings, this aligns with the nitrogen balance calculation system where ammonia emissions are tracked separately from nitrate.
335-338: LGTM!The updated chart component usage with
type="farm"andbalanceDataprop aligns with the discriminated union API introduced in NitrogenBalanceChart. This cleanly separates farm-level from field-level visualization concerns.fdm-calculator/src/balance/nitrogen/emission/ammonia/fertilizers.ts (3)
36-36: LGTM!Adding the explicit type annotation
(acc: NitrogenEmissionAmmoniaFertilizers, application)improves type safety and makes the reduce callback's intent clearer.
77-83: LGTM!The enriched application record with
p_id_catalogue,p_type, andp_app_dateenables richer downstream reporting and aligns with the updatedNitrogenEmissionFertilizertype structure.
141-149: No action needed;p_app_dateis guaranteed to be non-null by the type system.The
FertilizerApplicationtype definition marksp_app_dateas a requiredDateproperty, not optional. TypeScript will prevent anyFertilizerApplicationobjects without a valid date from reaching this code. The comparisons are type-safe.Likely an incorrect or invalid review comment.
fdm-app/app/routes/farm.$b_id_farm.$calendar.balance.nitrogen.$b_id.tsx (1)
396-400: LGTM!The updated chart props correctly implement the field-mode interface with
type="field",balanceData, andfieldInput. This enables the richer per-fertilizer and per-cultivation visualization capabilities. Based on learnings about nitrogen balance charts, the separation between farm and field modes with structured data inputs is a clean approach.fdm-calculator/src/balance/nitrogen/index.test.ts (2)
94-105: LGTM!The
assertValidFertilizerBreakdownhelper provides a clean, reusable way to validate the per-type fertilizer breakdown structure. The type annotation correctly captures the expected shape withtotaland the four fertilizer categories.
109-121: The test is correctly written;removalhas a flat structure and does not require nested validation likesupplyoremission.ammonia.The
removalfield inNitrogenBalance(the return type being tested) contains only simple scalar fields (total,harvests, andresiduesasDecimalvalues), unlikesupply.fertilizersandemission.ammonia.fertilizerswhich have complex nested structures with arrays and sub-objects. Additional validation forremovalis unnecessary.fdm-calculator/src/balance/nitrogen/types.d.ts (4)
186-202: LGTM!The new
NitrogenEmissionFertilizertype properly captures individual application-level detail with metadata fields (p_id_catalogue,p_type,p_app_date) that enable richer chart tooltips.
231-252: LGTM!
NitrogenEmissionAmmoniaFertilizersTotalprovides a clean aggregated structure for farm-level totals by fertilizer type.
373-405: LGTM!The expanded
NitrogenBalancetype with nestedsupply,removal, andemissionstructures properly exposes the per-category breakdowns needed for the enhanced chart visualization.
627-658: LGTM!The
NitrogenBalanceNumerictype correctly mirrors theNitrogenBalancestructure withnumberinstead ofDecimal, maintaining type consistency for the conversion layer.fdm-app/app/components/blocks/balance/nitrogen-chart.tsx (1)
612-613: LGTM!Supply and removal/emission correctly use separate
stackIdvalues ("a" and "b"), which aligns with the nitrogen balance chart design pattern where supply inputs should be visually separated from removal and emission outputs. Based on learnings.

Learning: In the organic matter balance calculation system (fdm-calculator), degradation values are negative by definition. This means the balance calculation using supply.total.plus(degradation.total) is correct, as it effectively computes supply - |degradation|. This follows the same pattern as the nitrogen balance system.

Learning: In the organic matter balance chart (fdm-app), degradation values are multiplied by -1 before plotting to show supply and degradation bars side-by-side with positive magnitudes, enabling direct visual comparison. This is a deliberate design choice for the organic matter chart visualization, different from the nitrogen balance chart which uses separate stacks.

Learning: In nitrogen balance calculations for agricultural systems, removal and volatilization are calculated as negative values by definition since they represent nitrogen losses from the system.

Looks good, just a remark about the output data of the balance. Also when hovering over the chart the tooltip does not always update. Also the highlighted outline is not always visible and could be made a bit more visible, e.g. use a bigger width

NitrogenEmissionFertilizerhelper nicely centralizes the{ total, applications[] }shape used for fertilizer emissions. For symmetry and future refactors, you could:
- Introduce a
NitrogenEmissionFertilizerNumericand use it inNitrogenEmissionAmmoniaFertilizersNumericto DRY the numeric side.- Optionally mirror other docs by explicitly stating the kg N/ha units in this JSDoc, even though it is indirectly covered by the parent ammonia type.
228-248: AggregatedNitrogenEmissionAmmoniaFertilizersTotalmatches intended chart aggregate; consider a numeric aliasThe aggregate
{ total, mineral, manure, compost, other }shape is exactly what you need for farm-level/chart summaries and cleanly separates it from the per-application structure.To keep Decimal and numeric models parallel and avoid repeating this shape, consider adding a
NitrogenEmissionAmmoniaFertilizersTotalNumericand using it inNitrogenBalanceNumeric.emission.ammonia.fertilizers.

NitrogenEmissionFertilizerformineral,manure,compost, andotherkeeps these sources consistent and matches the existing numeric shape (total + applications). This is a clean, non-breaking refactor from a typing perspective.
370-382: Nested supply/removal/emission aggregates look consistent; please re-check balance formula and sign conventionsThe new nested structures in
NitrogenBalanceandNitrogenBalanceNumeric(per-source supply, per-cause removal, and ammonia emission aggregates) are internally consistent and mirror each other well, which should work nicely for the enhanced charting.Please double-check in the calculator logic (
index.tsand tests) that:
supply.*remains positive, whileremoval.*andemission.ammonia.*still use negative values as before.- The overall balance continues to use
emission.ammonia.totalonly (excluding nitrate) together withsupply.totalandremoval.totalwhen computingbalance.Based on learnings, removal and volatilization are negative by definition and nitrate emissions must be excluded from the nitrogen balance formula.

Learning: In the nitrogen balance calculation system (fdm-calculator), removal and volatilization values are negative by definition. This means the balance calculation using supply.total.add(removal.total).add(volatilization.total) is correct, as it effectively computes supply - |removal| - |volatilization|.

Learning: In the FDM application, the fertilizer application route intentionally uses `${calendar}/field/fertilizer` instead of the originally planned `/farm/{farmId}/add/fertilizer` structure. This design decision prioritizes starting from the field list view to provide better field selection workflow before applying fertilizer, rather than direct dashboard-to-action navigation.

Learning: In nitrogen balance charts, supply should be in a separate stack from removal and emission. Supply represents nitrogen inputs while removal and emission represent different types of nitrogen outputs, so they should be visually grouped differently using different stackId values.

Learning: In nitrogen balance calculations for agricultural systems, removal and volatilization are calculated as negative values by definition since they represent nitrogen losses from the system. The balance calculation uses addition (.add()) for all components because removal and volatilization are already negative, so adding them effectively subtracts the losses from the supply.

253-274: Totals-only fertilizer ammonia type looks consistent with detailed per-source shape
NitrogenEmissionAmmoniaFertilizersTotalcleanly mirrors the per-type keys ofNitrogenEmissionAmmoniaFertilizerswhile intentionally omitting per-application arrays, which is appropriate for farm-level aggregation and chart usage. No issues from a type-shape perspective.
395-407: Farm-level NitrogenBalance structure matches intended breakdownThe new
NitrogenBalance.supply,removal, andemission.ammoniaobjects give exactly the farm-level totals you need for the chart (per-source supply, per-loss-category removal, per-fertilizer and residue ammonia totals) while staying compatible with the field-level detailed types. This aligns with the PR objective to expose fertilizer-type and residues/harvest/fixation contributions explicitly.Please double-check all fdm-calculator callers that previously treated
supply,removal, oremission.ammoniaas plainDecimal/numberare updated to use the new nested shape, especially any serialization or API response mapping.Also applies to: 411-415, 421-425
649-661: Numeric NitrogenBalance mirrors Decimal structure correctly
NitrogenBalanceNumeric’ssupply,removal, andemission.ammoniastructures are the numeric counterparts of the updatedNitrogenBalancetype (including per-fertilizer totals and residue ammonia), which will keep calculator outputs and fdm-app consumption in sync. The per-type keys are consistent across Decimal and numeric forms.Also applies to: 662-666, 669-679
fdm-app/app/components/blocks/balance/nitrogen-chart.tsx (3)
162-183: Farm-mode aggregation logic for fixation, removal, and fertilizer breakdown looks soundThe farm branch correctly:
- Uses
supply.fixation,removal.harvests,removal.residues, andemission.ammonia.residuesas already-aggregated farm totals.- Iterates
["mineral","manure","compost","other"]to populate supply and ammonia emissions per fertilizer type from the newsupply.fertilizersandemission.ammonia.fertilizersmaps.- Applies
Math.absto keep bar magnitudes positive while still respecting the sign semantics from the calculator.This matches the new farm-level
NitrogenBalanceNumericstructure and the PR goal of exposing per-fertilizer and residues/harvest contributions.
395-415: Supply vs removal/emission are correctly split into separate stacks
supplyBarandallRemovalBarare rendered with differentstackIdvalues ("a"and"b"), so supply is visually separated from removal and emission as per the nitrogen chart design guidelines. The way you composesupplyBarandallRemovalBar(including nitrate, fertilizer ammonia, and residues) matches the new balance breakdown and keeps the stacking semantics clear.Also applies to: 619-620
1-8: Fixdate-fnsimport and correctFieldInputtype aliasTwo critical issues:
date-fnsimport is invalid
import { format } from "date-fns/format"mixes named import syntax with a subpath, which will fail at build time. Use:import { format } from "date-fns"
FieldInputtype alias is wrong
Line 19 aliasesFieldInputto the entireNitrogenBalanceInput(which has shape{ fields: FieldInput[], fertilizerDetails, cultivationDetails, timeFrame }), but the component uses per-field properties likefieldInput.fertilizerApplications,fieldInput.cultivations, andfieldInput.harvests. These belong to the per-fieldFieldInputtype, not the wrapper.

Update nitrogen balance types to reflect actual data used in charts
The FieldInput type in fdm-calculator/src/balance/nitrogen/types.d.ts declares cultivations as a Pick<Cultivation, "b_lu" | "b_lu_start" | "b_lu_end" | "b_lu_catalogue" | "m_cropresidue">, but the nitrogen chart component accesses b_lu_name and b_lu_croprotation directly on cultivation objects (lines 63, 67, 74). While collectInputForNitrogenBalance returns full Cultivation objects at runtime, the type definition should include these properties to ensure type safety and clarity. Either expand the Pick to include "b_lu_name" | "b_lu_croprotation" if they are always present, or document why the type intentionally restricts these fields and adjust the chart component to always access them through b_lu_catalogue instead.

Recharts Bar component event handler payload structure tooltipPayload
💡 Result:
Short answer — Bar event handlers receive (data, index, event). The first argument is the "entry" / graphical item for that bar; the tooltip payload (what Tooltip renders) is an array of objects shaped like:
- name: string (label shown)
- value: number | string (formatted/unformatted value)
- payload: object (the original data object for that x/tick)
- dataKey: string | number (the Bar's dataKey)
- unit?: string
- color/stroke/fill?: string (series color)
- others depending on formatter/customizations
Example onMouseEnter signature and how you might read tooltip info:
onMouseEnter={(entry, index, e) => {
// entry often looks like: { value: 2400, payload: { name: 'Page A', uv: 2400, pv: 2400 }, dataKey: 'uv', name: 'uv', color: '#8884d8' }
// Tooltip payload (Tooltip.props.payload) is an array of similar objects:
// [{ name:'Page A', value:2400, unit:'kg', payload: {...}, dataKey:'uv', fill:'#8884d8' }]
}}

Recharts Bar event handlers use incorrect event shape
The onTooltipFocus and onTooltipBlur handlers assume a tooltipPayload structure that Recharts Bar components do not provide. Recharts 2.15.4 Bar onMouseEnter/onMouseLeave handlers receive (dataItem, index, event) where dataItem is an object containing the dataKey property directly, not a tooltipPayload array.
The current code will throw a runtime error when hovering over bars:
const dataKey = e.tooltipPayload[0].dataKey // ❌ e.tooltipPayload is undefinedUse destructuring to access dataKey directly:
const onTooltipFocus = ({ dataKey }: { dataKey: string }) => {
if (dataKey && tooltipFocus !== dataKey) setTooltipFocus(dataKey)
}
const onTooltipBlur = ({ dataKey }: { dataKey: string }) => {
if (dataKey && tooltipFocus === dataKey) setTooltipFocus(undefined)
}Remove the incorrect ChartMouseEvent type definition and update the handlers at lines 440–448 and their usages at lines 497–498 and 515–516.

- index — the index of that datum in the chart data array.
- event — the native mouse event (optional third argument).

🌐 Web query:
Recharts Bar onMouseEnter how to get which dataKey bar was hovered
💡 Result:
Use the Bar's event handler args (data, index, event) or capture the Bar's dataKey in a closure. Example patterns:
-
Handler receives the hovered bar's datum and index — you can derive dataKey from index or datum:
const handleEnter = (datum, index, e) => {
// datum is the row object for that bar; index is the bar's index
console.log(datum, index);
};
. [1][2] -
If you need the Bar's dataKey (when multiple Bars), capture it in the handler/closure:
const onBarEnter = dataKey => (datum, index, e) => {
console.log('hovered dataKey:', dataKey, 'value:', datum[dataKey]);
};
<Bar dataKey="pv" onMouseEnter={onBarEnter('pv')} />
<Bar dataKey="uv" onMouseEnter={onBarEnter('uv')} />. [1][3] -
Another common pattern: store the hovered dataKey via onMouseOver/onMouseEnter and read it from the Tooltip's payload (custom tooltip uses payload entries with .dataKey). [2]

shadcn/ui chart component Recharts Bar onMouseEnter event handler
💡 Result:
Short answer: Use Recharts' onMouseEnter on the Bar (or BarChart) exactly as you would in Recharts — shadcn/ui's Chart components are just Recharts + small helpers. Attach an onMouseEnter handler to ; the handler receives (data, index, event) and you can use that to show/move a custom Tooltip or update component state.
Minimal example (inside a shadcn ChartContainer):
"use client"
import { Bar, BarChart, XAxis, Tooltip } from "recharts"
import { ChartContainer, ChartTooltipContent } from "@/components/ui/chart"
const data = [{ month: "Jan", value: 10 }, { month: "Feb", value: 20 }]
export function MyChart() {
const handleBarEnter = (datum, index, e) => {
// datum = hovered bar's data object
// index = index in data array
// e = mouse event (contains e.x, e.y for positioning)
console.log(datum, index, e.clientX, e.clientY)
// e.g. set tooltip position or mark active index
}
return (
<ChartContainer className="min-h-[200px] w-full">
<BarChart data={data}>
<XAxis dataKey="month" />
<Tooltip content={<ChartTooltipContent />} />
<Bar dataKey="value" fill="var(--chart-1)" onMouseEnter={handleBarEnter} />
</BarChart>
</ChartContainer>
)
}

- Example pattern: capture e.x/e.y in Bar onMouseEnter to position a custom Tooltip. [3]

@BoraIneviNMI, yes, I checked the official Recharts documentation. The official Recharts Bar API documentation is available at:
https://recharts.github.io/en-US/api/Bar/
According to the official documentation and multiple sources, the onMouseEnter and onMouseLeave event handlers on the Recharts Bar component receive the signature: (data, index, event) where:
datais the data entry for that barindexis the index in the data arrayeventis the React mouse event
However, the code uses a ChartMouseEvent type that assumes e.tooltipPayload[0].dataKey, which doesn't match the standard Recharts signature. The code uses shadcn/ui Chart components (ChartContainer, ChartTooltip), which are wrappers around Recharts but don't modify the event handler signatures.
That said, if this code is currently working in your application, there may be something about your specific setup that I'm not seeing from the static analysis. Could you verify whether:
- These handlers are actually being called successfully when hovering over bars?
- If so, what does the actual event object structure look like at runtime?
If the code is working, I may need to revise my understanding based on the actual runtime behavior.

Learning: In nitrogen balance charts, supply should be in a separate stack from removal and emission. Supply represents nitrogen inputs while removal and emission represent different types of nitrogen outputs, so they should be visually grouped differently using different stackId values.

Learning: When handling different map event types in react-map-gl v7.1.8, use MapLayerMouseEvent for mouse events (which have the point property) and ViewStateChangeEvent for view state changes. Use a type guard like 'point' in evt to safely access event-specific properties.

Learning: In the fdm project, fdm-calculator integration for new features like b_lu_variety is handled in separate updates from the core data model changes. When fdm-core functions are updated to support new fields, fdm-calculator can consume these enhanced APIs without requiring changes in the same PR that introduces the core functionality.

It does work, and also on one of my coworker's machine. I have already spent hours trying to find the correct solution but I always had to resort to a hack. The mouse event always had the tooltipPayload property as we expect.
In Recharts v3 it seems they will add support to show one dataKey even in the default label content. If we can't extract the dataKey in a documented manner with the current version of shadcn and recharts, then we will wait until shadcn supports Recharts v3.
Here is an example with Recharts v3:

@BoraIneviNMI, thank you for the clarification and for taking the time to test this thoroughly! I apologize for the incorrect suggestion. You're absolutely right - if the code works on multiple machines and the tooltipPayload property is present in the mouse events, then my analysis based on standard Recharts documentation was mistaken.
It appears that shadcn/ui's Chart components are modifying or augmenting the Recharts event structure in ways that aren't captured in the standard Recharts v2 documentation. Since you've confirmed the current implementation works correctly, there's no need to change it.
I appreciate you sharing the context about Recharts v3 as well. Given that your current solution is functional, you can keep it as-is until you decide to upgrade when shadcn supports Recharts v3.
Again, sorry for the noise on this one!

Learning: In the fdm project using shadcn/ui Chart components with Recharts 2.15.4, the Bar component's onMouseEnter and onMouseLeave event handlers receive an event object that includes a tooltipPayload property with the structure { tooltipPayload: { dataKey: string }[] }, which differs from standard Recharts v2 documentation but is confirmed to work in practice. This appears to be a modification made by shadcn/ui's Chart wrapper components.
