The Power of Gnuplot, Simplified

For decades, Gnuplot has been the industry standard for scientific visualization. However, local installation and environment configuration can sometimes be a hurdle for students or researchers on-the-go. Our Online Gnuplot Editor removes these barriers, providing a native-like experience directly in your web browser.

Powered by WebAssembly (WASM), this terminal runs entirely on the client-side. This means your data never leaves your computer, ensuring 100% privacy and security for sensitive research datasets.

No Setup

Skip the compilers and PATH configurations.

Cross-Platform

Works on Chromebooks, iPads, and restricted workstations.

Frequently Asked Questions

Everything you need to know about using Gnuplot in a browser environment.

Q: Can I plot my own data files in this online terminal?

A: Yes, but with a slight difference from the desktop version. Since the browser cannot directly access your hard drive for security reasons, you typically need to use the “inline data” format (using plot '-') or copy-paste your dataset directly into the script. For large-scale data processing, we recommend downloading the desktop version.

Q: Which Gnuplot version is running here?

A: This environment is powered by Gnuplot-JS, a port of the Gnuplot source code to JavaScript/WebAssembly. It generally tracks the stable 5.x or 6.x core features, though some specific hardware-dependent terminals (like wxt or windows) are replaced by the SVG and Canvas terminals.

Q: How do I save my generated plots?

A: Most browser-based Gnuplot terminals will render the output as an SVG or PNG image. You can usually right-click the resulting image and select “Save Image As…” to download it to your device for use in LaTeX or Word documents.

Q: Is my script data safe?

A: Absolutely. Because the engine runs locally in your browser via WebAssembly, your scripts and data points are not uploaded to our server. Your intellectual property stays on your machine.
