Overview

Plots

Plots is a graph plotting app for GNOME. Plots makes it easy to visualise mathematical formulae. In addition to basic arithmetic operations, it supports trigonometric, hyperbolic, exponential and logarithmic functions, as well as arbitrary sums and products.

Plots is designed to integrate well with the GNOME desktop and takes advantage of modern hardware using OpenGL, and currently supports OpenGL 3.3+.

Other Methods of Installation

We are looking for volunteers to help us make native packages of Plots for Fedora, Arch and other major distributions. It would be great if you could help either by packaging, or by getting the following into the official repositories.

Distribution	Package	Maintainer
Ubuntu	PPA	Archisman Panigrahi
Debian	.deb installer	Archisman Panigrahi
Arch	AUR/AUR(git)	Mubashshir

Scroll down and click on a package name to download the .deb file from the PPA to use it in Debian.

You can also install with Python. Open a terminal in the repository and run

# python3 setup.py install

Note that this method does not currently install the icon, font or .desktop files. You can then run Plots using the plots command.

Screenshots

Development

Running from source

To run directly without installation, open a terminal in the root of the repository and run

$ python3 -m plots

Building the Flatpak

To generate the manifest for the python modules, download flatpak-pip-generator and run

$ python3 flatpak-pip-generator --requirements-file=flatpak-requirements.txt --no-build-isolation

It is only necessary to do this when flatpak-requirements.txt changes.

Then build and install the Flatpak using

$ flatpak-builder --user --install build --force-clean com.github.alexhuntley.Plots.json

Comments

Strange artefacting when doing y = x^(4/3)

Screenshot speaks for itself I think:

This only happens on my laptop which uses Intel graphics (Intel HD 5000). My desktop, which uses NVIDIA graphics with the proprietary driver version 495.46, does not exhibit this issue:

Plots was installed from Flathub on both systems.

Created PPA and updated README with installation instructions

I have created a PPA for Ubuntu and derivatives. I have tested that it works in Linux Mint 20. The .deb package automatically downloads the Latin Modern Math font after the installation, and the user experience should be identical to the flatpak version (but the total download size would be less than 1 MB).

I have also added the installation instructions for the PPA and with setup.py.

Once this is merged, I can also create a Daily Builds PPA, which will use the latest code in this repository to automatically build a .deb package in Launchpad.

I think it could need some "Help page" with the list of operations you can use and how you can type them :)

Color picker improvements

What do you think about making the color selection task simpler by converting the color selection to a popup dialog?

It would make imho the mouse travel shorter and the selection more intuitive.

Improve contrast

Currently functions can be hard to see, both because the grid lines are very strong, and also because the function lines have different thicknesses depending on how steep they are. I'd recommend toning down the grid, and making the line thickness the same regardless of the function.

AdwAboutWindow

Hello! This is an attempt to port the app to use the new AdwAboutWindow:

To be able to use AdwAboutWindow, I had to update the runtime to GNOME 43, but that breaks the NumPy build, so I applied the workaround suggested here.

Please tell me if I'm doing anything wrong, I'm still kinda new to this, despite following GTK (and libadwaita) internals for years.

Reduce the color contrast between the grid and the axes

Hi!

Can you please consider reducing the contrast between the color of the grid and that of the main axes?

As you see, it's pretty difficult to distinguish them. Also, the grid is so promiment that it makes difficult to see some functions of parts of them. In fact, have you noticed that in the above picture I plotted f(x) = 2? 👀
