- Design, create, and revise Google Sheets charts with better chart-spec recall and editing discipline. Use when the user wants to add a chart to a sheet, choose the right chart type for existing data, repair a broken chart, update a chart's data series, or reposition or resize a chart after creating it.
Google Sheets Chart Builder
Use this skill when the chart itself is the task.
Read ./references/chart-recipes.md before the first chart write. The point is to refresh chart request shapes and a few non-obvious API constraints before building or editing.
Workflow
- Ground the chart in the live sheet first: exact source tab, domain column, series columns, headers, and whether the data is contiguous.
- Choose the simplest chart type that matches the table shape and user intent.
- Draft one chart spec first, using a clean anchor position that will not collide with existing content.
- If the chart needs revision, update the chart spec deliberately rather than trying to patch a tiny nested fragment from memory.
- Treat chart content changes and chart position changes as separate operations.
Output Conventions
- Name the source sheet and the exact domain and series ranges.
- State the chosen chart type and why it fits the data.
- For edits, state whether you are changing the chart spec, the chart position, or both.
References
- For chart-type heuristics, request-shape reminders, and official Google Sheets docs links, read
./references/chart-recipes.md.
