Metadata
name
chart
description
Local-first chart generation engine for trends, comparisons, distributions, and quick visual explanations. Use whenever the user wants to visualize data, compare numbers, plot a trend, turn CSV or JSON into a chart, or decide which chart type fits a dataset best. Generates charts locally and stores outputs in the user's workspace.

Chart

Turn numbers into clear visuals.

Core Philosophy

  1. Prefer clarity over chart variety.
  2. Choose the simplest chart that makes the comparison obvious.
  3. Use local generation only.
  4. Make outputs reusable for reports, slides, and quick decision-making.

Runtime Requirements

  • Python 3 must be available as python3
  • matplotlib must be installed
  • No network access required

Storage

All data is stored locally only under:

  • ~/.openclaw/workspace/memory/chart/charts.json
  • ~/.openclaw/workspace/memory/chart/output/

No cloud sync. No third-party chart APIs.

Supported Chart Types

  • bar: category comparison
  • line: trend over time
  • pie: simple part-to-whole
  • scatter: relationship between two variables

Key Workflows

  • Suggest: suggest_chart.py --labels ... --values ...
  • Generate: make_chart.py --type bar --title "..." --labels "A,B,C" --values "10,20,15"
  • History: list_charts.py
  • Initialize: init_storage.py

Scripts

Script Purpose
init_storage.py Initialize local chart storage
make_chart.py Generate a chart image from inline data
suggest_chart.py Recommend the best chart type
list_charts.py Show previously generated charts
