Version 1.7 marks our biggest release yet. With a migration to GNOME 45 and a new UI overhaul with a revamped style editor.
Other major highlights include a new curve fitting functionality, the ability to open projects directly, and support for gestures in the canvas. A full changelog can be found below:

New in Graphs:

  • The style editor has been revamped completely and now shows previews for each style
  • Curve fitting functionality has been added to Graphs
  • Graphs can now open data as well as Graphs project files directly from the file manager
  • When closing the application while unsaved changes are present, a dialog is now shown allowing you to save the data
  • The active project and its directory are now shown in the headerbar, including an indicator for unsaved changes
  • Graphs now includes forwards/backwards buttons to quickly navigate to the next and previous view
  • The smoothening action can now be configured with a choice of two different filters, a rolling average and a LOESS Savitzky-Gotsky filter
  • A new Yaru style has been added, which is set as the default system style for the Snap package when Yaru is used in the system, offering a more consistent experience
  • The default matplotlib style has been added to Graphs
  • The title font size can now be changed with respect to the overall font size
  • New scaling options are available for the axes, allowing for radian, square root and inverse scaling
  • Transparent colors for the curves are now supported
  • Superscript characters are now supported when entering equations
  • Support has been added for cotangents, secants and cosecants for equations and transformations
  • Headers are now written to exported files if present in the originally imported data
  • Style sheets now allow you to choose whether a frame should be drawn around the axes
  • The size of the title and labels can now be set separately in the style editor
  • Importing column data is now more robust, supporting expressions as data points
  • Pinch and ctrl+scroll to zoom gestures are now supported on the canvas
  • The canvas can now be panned using two fingers on a touch screen, as well as with the middle mouse button
  • Toasts now show an "Open Location" button when saving data, bringing you to the saved file location
  • Translate/multiply entries now get a red CSS when input value is invalid, while the corresponding button is disabled

Changed behaviour:

  • Several linguistic changes were made, to get a clearer and more consistent description
  • The syntax for equations has been simplified
  • Delimiters can now be specified from a dropdown menu instead of having to rely on regex
  • The used axes limits are now saved when saving/loading a project
  • Settings related to specific axes are now only displayed when the axis is in use
  • The preferences have been redesigned and simplified, leaving only a single dialog for the figure settings
  • The drag and drop animation when moving items has been improved
  • The headerbar now follows the color of the used stylesheet, giving a more unified look
  • The shortcuts have been modified to follow the rest of the GNOME ecosystem
  • The logic for placing the legend has been changed, so that it now properly moves away when it intersects with a curve
  • The behavior of the "Shift" action has been revamped to be more consistent when only part of the data span is selected

Bugfixes and changes under the hood:

  • Graphs has been migrated to GNOME 45, and uses the new Libadwaita 1.4 widgets
  • Number inputs are now handled safely without calling the Python eval function
  • The clipboard implementation has been rewritten from scratch
  • The scale buttons in the view menu are now properly changed when the scale has been changed from the figure settings
  • Automatic scaling is now handled properly even when the dataset contains infinite values
  • Graphs now uses unit tests, reducing the risk of regression bugs
  • Part of the code-base has been migrated to Vala
  • Fixed a bug where "Skip rows" did not work properly with single-column data
  • Fixed a bug where rows would change width when selected in case they are adjacent to other entry rows
  • Graphs translations are now hosted on Weblate
  • More smaller changes and fixes throughout the code-base
