bash
pytest

vii).Submit a Pull Request

Push your branch and open a pull request on GitHub. Add a meaningful description and link to any related issues.

Understanding the Codebase Structure

Familiarize yourself with PyQtGraph’s key folders:

• /pyqtgraph/ – Core modules and plotting logic
• /examples/ – Usage examples
• /tests/ – Unit and regression tests
• /docs/ – Documentation and markdown files

Tip: Start with smaller files like PlotWidget.py or functions.py if you’re a beginner.

Contributing to Documentation

Clear, complete documentation is as valuable as clean code.

Ways to Help:

• Fix typos or outdated information in .md or .rst files.
• Add usage examples to the examples folder.
• Improve API documentation using Python docstrings.
• Translate docs to other languages if needed.

You can edit the markdown files directly or use tools like Sphinx to generate updated docs.

Reporting Bugs and Requesting Features

If you encounter a bug, open a detailed issue at:

👉 https://github.com/pyqtgraph/pyqtgraph/issues

Guidelines for Reporting:

• Provide your OS and Python version
• Include a minimal reproducible example
• Use clear, concise language
• Include screenshots if helpful

For feature requests, explain the need clearly and suggest a possible implementation if you have one.

Community Support and Discussion

You can contribute just by being part of the conversation.

Where to Help:

• GitHub Discussions
• Stack Overflow (Tag: pyqtgraph)
• Discord / Gitter (if available)

By answering questions and offering solutions, you support new users and lighten the load for maintainers.

Creating Tutorials and Content

If you’re more of a creator than a coder, contribute through content.

Ideas for Tutorials:

• How to install PyQtGraph
• Building a real-time sensor dashboard
• Custom GUI layouts using PlotWidget and QGridLayout
• Exporting PyQtGraph plots to images

You can share these via Medium, YouTube, Dev. To, or on your blog and link them in the community.

Becoming a Long-Term Contributor

Want to contribute regularly? Here’s how:

• Pick a module and “own” it by fixing related issues
• Join release testing when a new version is close
• Review and comment on other people’s PRs
• Follow the GitHub repo to get notifications

Eventually, you could become a trusted maintainer or get invited to the core team.

Best Practices for Open Source Contribution

To contribute effectively and professionally:

• Follow PyQtGraph’s contribution guidelines and code style
• Write descriptive commit messages
• Stay respectful in discussions and reviews
• Ask questions — collaboration is key
• Test your changes thoroughly

Reading the CONTRIBUTING.md and README.md files is always a great starting point.
