Problem

The Sheets chart CLI schema and local examples did not expose bubble, waterfall, or pareto chart configurations, so callers could not discover or construct these chart types reliably.

Changes

  • Sync the chart property schema and chart skill reference from sheet-skill-spec MR https://code.byted.org/ee/sheet-skill-spec/merge_requests/87
  • Add ready-to-edit examples for bubble, waterfall, and pareto
  • Preserve bubble data roles, waterfall global options, and pareto bar/cumulative-line series roles
  • Add contract coverage for the three templates

The runtime chart support is tracked in https://code.byted.org/ee/byted-sheet/merge_requests/4112.

Verification

  • go test -count=1 ./shortcuts/sheets/...
  • go vet ./shortcuts/sheets/...
  • ./build.sh
  • Local --print-example and deep --print-schema checks for all three chart types

Summary by CodeRabbit

  • New Features
    • Added ready-to-edit examples for bubble, waterfall, and pareto charts.
    • Added support for creating and updating scatter, bubble, waterfall, and pareto charts.
    • Added chart-specific configuration for data mappings, labels, formatting, and series settings.
  • Documentation
    • Updated chart command guidance and examples to include the newly supported chart types.

--print-example metadata and chart documentation now list and describe the new chart types.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🔵 Low · up to cbc28

The Pareto example and documentation currently disagree with the chart schema and use an unsupported label-format field, while its contract test does not fully verify the intended bar and cumulative-line roles. This could lead users to copy invalid or misleading configurations, so merge is reasonable with explicit owner follow-up on these localized fixes.

Strengthen the pareto assertions so they pin the plot series roles.

The markers "index": 1 and "index": 2 also match the pareto template data block, where dim1.serie.index is 1 and dim2.series[].index is 2. If the plotArea.plot.series block is removed, this test still passes. The PR states that the bar series and the cumulative-line series roles are part of the contract, so assert the distinguishing keys or parse the template and read the series entries.

Lark Sheets chart series data labels format property plot series labels format chart schema

💡 Result:

In Lark Sheets, managing data labels and their formatting involves specific structural configurations, particularly when working with the Lark Sheets API or CLI tools [1][2]. 1. Data Label Toggle Mechanism: Data labels are controlled by the presence of the plotArea.plot.labels object within the chart's properties [1][3]. - To show data labels: Include the labels object in your configuration and specify desired components such as value, category, series, or percentage [1][4]. - To hide data labels: The entire labels field must be omitted from the JSON structure [3][4]. Simply setting its internal boolean properties (e.g., value: false) is ineffective, as the mere existence of the labels object triggers the system to display labels (defaulting to showing the value) [1][3]. 2. Formatting Numerical Values: Lark Sheets does not support arbitrary format or number_format fields within the chart's axis or label schema definitions; attempting to include them will trigger an error (e.g., unexpected property "format" is not defined in schema) [1][4]. Instead, numerical formatting must be applied at the data source level [1][5]: - Apply the desired number format (e.g., currency, percentage, decimal places) directly to the source cells in the sheet using the cell_styles.number_format property [1][4]. - The chart component will automatically inherit and reflect the formatting established in the source cells [1][5]. 3. Chart Schema Structure: When interacting with the chart via automation (such as the Lark CLI), the configuration is passed via the --properties argument, which expects a JSON structure containing position, offset, size, and snapshot [1][2]. The specific data label settings are located within snapshot.plotArea [1][2]. Developers are advised to use the command lark-cli sheets +chart-create --print-schema --flag-name properties to view the exact, up-to-date schema structure for their specific environment [1][5]. Note: If you are using Lark Cards for custom visualizations, these follow the VChart (VisActor) specification rather than the native Sheets chart schema, and you should refer to VChart documentation for configuring those specific specs [6][7][8].

Remove labels.format from the Pareto template. Chart labels do not support format or number_format; use the source cell’s cell_styles.number_format instead.

排列图的源数据列仍由 `snapshot.data.dim1.serie.index`(类别列)和 `snapshot.data.dim2.series[].index`(数值列)指定。不要把 `plot.series[].index` 与源数据列索引混为一谈。

Align the Pareto plot.series[].index contract. flag-schemas.json defines this field as a source data-column index matching dim2.series[].index, but the Pareto documentation and template use 1 and 2 as output-series roles. Add a Pareto-specific exception to both chart schemas, or update the documentation and template to follow the schema contract.
