Extract pixel-level data from an image of a chart or graph and produce a structured data table. Use when asked to extract data from a chart image, transcribe numbers from a graph, digitise a chart, or turn a screenshot of data into a table. Produces a structured table with extracted values, confidence levels, and a reconstructed chart source. Best used with Claude Opus 4.7 or newer for reliable chart data extraction.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chart Data Extractor Skill Extracts data from images of charts and graphs — bar charts, line charts, pie charts, scatter plots, and tables in images — producing a structured data table that can be used in spreadsheets or rebuilt in any charting tool. Built to leverage Opus 4.7 pixel-level image analysis capabilities. ## Required Inputs Ask the user for these if not provided: - **The chart image** (upload a screenshot or image file) - **Chart type** (if ambiguous — bar / line / pie / scatter / other) - **What matters most** (approximate trends / precise values / specific data points / categorisation) - **Known axis values** (optional — if the user knows the max/min values to anchor the extraction) ## Output Structure ### 1. Chart Identification | Attribute | Value | |---|---| | Chart type | [Bar / Line / Pie / Scatter / Area / Other] | | Chart title (if visible) | [Title text] | | X-axis label | [Label + unit] | | Y-axis label | [Label + unit] | | Number of series | N | | Legend categories | [List] | | Data period (if time-based) | [Start — End] | ### 2. Extracted Data Table | [X axis] | [Series 1] | [Series 2] | ... | |---|---|---|---| | [Value] | [Value] | [Value] | | …

How to install
mdr add mohitagw15856/pm-claude-skills/chart-data-extractor@sha256:0c322cde8d08c191The line at the top of this page pins the label git:20260714.b87d8d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
