Prompt

When plotting noisy accuracy data from `epoch_stats.csv`, small visual curve differences in terminal can be hard to read precisely. What option appends an explicit tabular listing of exact plotted values right below the chart display?

Terminal Line Plot

Use this skill to turn numeric sequences into terminal-readable line charts. It is task-agnostic: do not assume any domain, metric direction, filtering rule, or data layout unless the user or artifacts define it.

Workflow

Identify the series to plot:
- x values are usually ordered steps, dates, versions, generations, epochs, or run ids.
- y values must be numeric.
- If multiple plausible metrics exist, choose the one the user asked for; otherwise state the selected metric before plotting.
Preserve metric semantics:
- Use exact metric names from artifacts when available.
- Label whether higher or lower is better if known.
- Do not mix partial and complete points silently; mark provisional or incomplete points in the title, notes, or point list.
Use scripts/plot_series.py for deterministic plotting.
Print a compact table or point list when it prevents misreading the curve.
Do not write image files unless the user explicitly asks. Prefer stdout.

Script Usage

Run the bundled script from the skill directory:

python /path/to/terminal-line-plot/scripts/plot_series.py \
  --points "0:-4.49,1:-4.53,2:-4.87,3:-4.77,4:-3.23" \
  --title "Best future_fitness by generation" \
  --x-label generation \
  --y-label future_fitness \
  --higher-better

Input options:

--points "x:y,x:y,..." for quick point lists.
--csv FILE --x-field FIELD --y-field FIELD for CSV.
--json FILE --x-field FIELD --y-field FIELD for JSON arrays of objects, arrays of pairs, or mappings.
--stdin csv|json|points to read data from stdin.
