Gnuplot Portable: Run Gnuplot Without Installing

You do not need administrator rights or a formal install to use gnuplot on Windows. The 6.0.5 release includes a portable .7z package: extract it to any folder — including a USB drive — and run gnuplot.exe directly. Nothing is written to the registry and nothing is added to your system PATH.

Step-by-Step: The Portable .7z Package

1. Download the portable package. The file gp605-win64-mingw.7z is part of the official 6.0.5 release on SourceForge and is linked from our download page.
2. Extract it. Use 7-Zip (or Windows 11’s built-in .7z support in Explorer) and extract to a folder you control, for example D:\gnuplot-portable on a USB drive or C:\Users\you\gnuplot on a locked-down work PC.
3. Run it. Inside the extracted folder, open the bin subfolder and double-click gnuplot.exe for an interactive session, or open a terminal in that folder and run:

   .\gnuplot.exe --version

   Expected: gnuplot 6.0 patchlevel 5.

4. (Optional) Make it easy to reach. Create a desktop shortcut to gnuplot.exe, or add the bin folder to your user PATH (Settings → Environment Variables) — a per-user change that needs no admin rights.

Running From a USB Drive

The portable build keeps its files in its own folder, so it runs the same from a USB stick on any Windows PC. Your scripts travel with it: keep your .gp files and data next to the executable folder and load them with relative paths, e.g. load "scripts/first.gp".

No Downloads Allowed? Use the Online Version

On machines where even extracting an archive is blocked, the online gnuplot terminal runs gnuplot directly in your browser — no download, no install, nothing left behind. It is a WebAssembly build of gnuplot 5.4 rather than 6.0.5, which covers the vast majority of everyday plotting commands.

Common Pitfalls

• Plots do not open or a DLL is missing: the archive was only partially extracted. Re-extract the complete .7z and keep the folder structure intact — the executable expects its neighbouring files.
• The terminal cannot find gnuplot: portable means no system PATH entry. Either run it from its own folder as shown above, or add the folder to your user PATH once.

Prefer a permanent setup later? The standard Windows installer guide takes five minutes.
