Free plan Linux

What Graphs is

Graphs is a free Linux desktop application for plotting and manipulating data, including work intended for scientific publications and presentations. It imports column-based files such as CSV, DAT, XY, and plain text, as well as ODS and XLSX spreadsheets, SQLite database files, Panalytical XRDML, Leybold XRY, and Graphs project files. Users can also generate datasets from equations and render equations continuously across the plot canvas. Data operations include translating, multiplying, normalizing, centering, smoothing, differentiating, integrating, Fourier transforming, combining, shifting, and cutting datasets, along with custom coordinate transformations. Curve fitting offers linear, quadratic, exponential, power law, logarithmic, sigmoid logistic, and Gaussian models, plus custom equations. Fit analysis can present parameter confidence margins, confidence bands, R², RMSE, and residual plots. For presentation, Graphs includes built-in styles and supports creating, editing, importing, or exporting custom styles for colors, fonts, lines, markers, error bars, axes, ticks, and grids. Figures can be exported as PNG, JPEG, WebP, SVG, PDF, PostScript, or Encapsulated PostScript, and underlying data can also be exported to files. Vector image exports can be edited in software such as Inkscape. Graphs is distributed from Flathub under the GNU General Public License v3.0 or later and costs nothing.

Who it suits

Graphs suits Linux desktop users who need to import, transform, fit, and present datasets. Its equation plotting, fit analysis, and export options also fit people preparing plots for scientific publications or presentations.

What it does well

Imports spreadsheets, text, database, and specialized data files.
Creates datasets from equations and plots equations continuously.
Offers predefined curve fits and custom equations.
Fit analysis can include confidence bands and residual plots.
Custom styles control plot elements from colors to grids.
Exports figures in raster and vector formats.

What to know first

Available platform is Linux only.
It is a desktop application rather than a hosted dashboard.
Scheduled refresh and embedded dashboards are not supported.

As apps.gnome.org lists them, read 9 Oct 2026. The maker's own page has the final word.

Getting started

Open the Graphs page on GNOME Apps or install it from Flathub.
Install the Linux desktop application.
Import a supported data file, spreadsheet, SQLite database, or Graphs project file.
Alternatively, generate a dataset from an equation.
Choose a plot style, perform data operations or curve fitting, then export the figure or data.

Verdict

Choose Graphs if you want a free Linux desktop tool for data plotting, transformations, fitting, and figure export. Look elsewhere if you need a non-Linux platform, scheduled dashboard refresh, or embedded dashboards.
