task_charts__scatter_points__axis_threshold_point_count

Contract

1. Domain: charts
2. Scene id: scatter_points
3. Public task id: task_charts__scatter_points__axis_threshold_point_count
4. Query ids encode the axis and threshold direction because both change prompt wording and program arguments.

Program Contract

Program: count(point, compare(coord(point, axis), threshold, direction)); output=integer_count; annotation=point_set(counted_point_centers); scene=scatter_points; scope=axis_threshold_point_count

Candidate set: the visible scatter points and axis/value labels inside the axis_threshold_point_count objective scope. Operands: prompt-bound labels, categories, series names, thresholds, intervals, references, and encoded chart values, plus the active query id's comparator, direction, target role, or extremum focus when present. Operation: evaluate count over the candidate set using the filters, comparisons, aggregations, rankings, projections, or counterfactual edits named in the program expression; generation enforces a unique final answer. Output binding: answer is the integer_count value bound by integer_count. Annotation witnesses: point_set witnesses bound by point_set(counted_point_centers). Annotation marks the centers of the counted scatter points only. Axes, legends, threshold guides, titles, and distractor text are not annotation targets. Query ids: x_above_threshold_count, x_below_threshold_count, y_above_threshold_count, y_below_threshold_count.

Reasoning Operations

Families: filtering, counting, comparison

Implementation

1. Registered class: trace_tasks.tasks.charts.scatter_points.axis_threshold_point_count.ChartsScatterPointsAxisThresholdPointCountTask
2. Prompt bundle: src/trace_tasks/resources/prompts/charts/scatter_points/charts_scatter_points_v1.json
3. Generation is deterministic from instance_seed, explicit params, prompt bundle, renderer config, and code versions.
4. Answers and annotation are produced from the same metadata execution trace.

Annotation Contract

1. Answer schema: integer_count.
2. Annotation schema: point_set.
3. Annotation marks the centers of the counted scatter points only.
4. Axes, legends, threshold guides, titles, and distractor text are not annotation targets.
