vector-plot-extractor

tools for extracting data from vector plots

This Python package has been tested on various PDF files, including example.pdf, under normal usage conditions. However, it has not undergone comprehensive testing and optimization yet. I will improve it in the future. Your suggestions and contributions are welcome.

A step-by-step tutorial is provided to demonstrate typical usage of the tool.

Dependencies

This package mainly depends on the following packages:

• matplotlib
• numpy
• pymupdf

These will be automatically installed when running pip install.

Installation

To install this package, you can simply use pip:

pip install vector-plot-extractor

If you would like to try the latest development version, you may directly install from the project repository by:

pip install git+https://github.com/ycwang-astro/vector-plot-extractor.git

Usage

To execute the main UI, run this in your terminal

vpextract path/to/figure/file

To import this package in a Python script:

import vpextractor

Limitations/caveats

It can be tricky to decide the underlying data for scatter plots. For some markers, there can be systematic errors (within the size of the markers) in the extracted data. A future version will add a UI with which you may manually select the relative position of data points for each marker.

It is at your discretion to verify the accuracy of the output results!

Notice

A bug in version 0.1.1 causes minor errors in the extracted scatter data. If you have used 0.1.1 version, follow the steps in the changelog ("Notes" under "0.1.2") to fix it.
