# 📊 Data Extractor

Get the numbers back out of a chart you only have as an image

## What this does

Sometimes the only version of a result you can get is a picture of a chart in a paper. This reads the image and gives you the numbers behind it, across many common plot types - bars, scatter plots, forest plots, survival curves, box plots and more. Reach for it when you need the underlying values and nobody published them.

### Top 3 things it does for you

- Pull data points off a published figure
- Read numbers from a bar chart, scatter plot or survival curve
- Recover values from a figure when the source data is gone
