Version 2.3

PlotPy Version 2.3.5 (2024-06-21)

This release is mainly intended to fix the Windows binary distribution, which was not supporting NumPy 2.0.

🛠️ Bug fixes:

• Moved back conftest.py to the tests folder (was in the root folder), so that pytest can be executed with proper configuration when running the test suite from the installed package

• Removed benchmarks from automated test suite (not relevant for the end user): added plotpy-benchmarks script to run the benchmarks

PlotPy Version 2.3.4 (2024-06-20)

In this release, test coverage is 79%.

🛠️ Bug fixes:

• Add support for NumPy 2.0:

  • Updated build system to use NumPy 2.0 on Python > 3.8 and NumPy 1 on Python 3.8

  • Use numpy.asarray instead of numpy.array(..., copy=False)

  • Use numpy.isin instead of numpy.in1d

  • Use scipy.integrate.trapezoid instead of numpy.trapz

• ColorMapManager: fix segmentation fault with PySide6 on Linux

PlotPy Version 2.3.3 (2024-06-13)

In this release, test coverage is 79%.

🛠️ Bug fixes:

• Moved up LineCrossSection import for consistency with other cross-section panels

• Unexpected behavior regarding io.load_items and io.save_items functions:

  • Those functions were serializing and deserializing most of the parameters of the plot items, but not their visibility state

  • This is now fixed: the visibility state of the plot items is now saved and restored as expected

ℹ️ Other changes:

• Explicitely exclude NumPy V2 from the dependencies (not compatible yet)

PlotPy Version 2.3.2 (2024-05-07)

In this release, test coverage is 79%.

Version 2.3.2 fixes a blocking issue with the colormap editor unit test introduced in version 2.3.1. The latter is a fugitive release that was not announced.

💥 New features / Enhancements:

• Colormap: added “Apply” button to the colormap manager

• Automated test suite:

  • Test coverage has been improved from 75% to 79%

  • The following features are now covered by unit tests:

    • Panning with the mouse move events

    • Zooming with the mouse wheel/move events

    • Curve statistics tool

    • Image rotation and translations via SelectTool (simulating mouse events)

    • Masked areas in images and ImageMaskTool

    • LockTrImageTool

    • Cursor tools (HCursorTool, VCursorTool, XCursorTool and HRangeTool)

    • DisplayCoordsTool: simulation of ‘Alt’ and ‘Ctrl’ keys

    • Complete coverage for MultiLineTool and FreeFormTool

    • Selection tools (RectangularSelectionTool and SelectTool)

🛠️ Bug fixes:

• Image statistics tool: fixed “No available data” message when the tool rectangular region top Y coordinate is above the image top Y coordinate

• Label items (LabelItem, LegendBoxItem, DataInfoLabel, …) were not emitting the SIG_ITEM_MOVED signal when moved interactively (with the mouse) if the item anchor was attached to the canvas

• Colormap: fixed context menu entry update (colormap icon was updated as expected, but the colormap name was not)

• Rotate/crop dialog: added missing toolbar on plot widget

• Flip/rotate dialog: added missing toolbar on plot widget

• Fixed issue with oblique averaged cross section computation (AttributeError when clicking on the empty cross section plot)

PlotPy Version 2.3.0 (2024-03-11)

In this release, test coverage is 75%.

💥 New features:

• Added support for colormap inversion:

  • The user can now invert the colormap of an image item:

    • From the image parameters dialog (“Invert colormap” checkbox)

    • From the plot context menu (right-click on the image item)

  • BaseImageItem.set_color_map method takes a new invert parameter (which defaults to None, meaning that the behavior is unchanged)

  • New ReverseColormapTool: registered by default in the plot widget, like the ColormapTool (add the “Invert colormap” entry in the context menu of the image)

🛠️ Bug fixes:

• ErrorBarCurveItem: fixed NumPy deprecation warning (“Conversion of an array with ndim > 0 to a scalar is deprecated […]”)

ℹ️ Other changes:

• Image plot items deserialization:

  • When an image plot item is deserialized, and needs to be reloaded from a file, the file path is adapted to the current working directory if file is not found (this is the legacy behavior).

  • An unnecessary call to ImageIOHandler.adapt_path method was removed from the RawImageItem.deserialize method: this issue has to be handled by the host application, not by the PlotPy library.

  • ImageIOHandler: removed add_change_path and adapt_path methods

• Fix typo in tests.features.test_colormap_editor module: renamed function test_colormap_manager to test_colormap_editor

• Removed unnecessary BaseImageItem.get_color_map_name method
