System Application · System.Tooling · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Performance%20Profiler/src/ProfilingChartHelper.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Internal |

## Procedures

- `GetChartData(ProfilingAggregationType: Enum "Profiling Aggregation Type"; AggregateBySelfTime: Boolean; ChartLabels: List of [Text]; ChartValues: List of [Integer])`: Gets the dictionary with aggregation type identifiers as keys, and aggregated self time / full time as values.
- `UpdateData(BusinessChartControlAddIn: ControlAddIn BusinessChart; ProfilingAggregationType: Enum "Profiling Aggregation Type"; BusinessChartType: Enum "Business Chart Type"; AggregateBySelfTime: Boolean)`: Updates the contents of the business chart control add-in for performance profiler charts.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 479 "Business Chart"](../codeunit/479.md) (6 calls: `UpdateData → AddDataRowWithXDimension`, `UpdateData → AddMeasure`, `UpdateData → Initialize`, …)
- [Codeunit 1923 "Profiling Data Processor"](../codeunit/1923.md) (3 calls: `GetChartData → GetFullTimeAggregate`, `GetChartData → GetSelfTimeAggregate`, `GetChartData → GetUniqueIdentifierByAggregationType`)

## Called by

- [Page 1922 "Profiling Self Time Chart"](../page/1922.md) (1 call: `UpdateData → UpdateData`)
- [Page 1925 "Profiling Full Time Chart"](../page/1925.md) (1 call: `UpdateData → UpdateData`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Profiling Chart Helper")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
