Full changelog

v0.10.0 (unreleased)

  • Change default name of subsets to include the word 'Subset'. [#1234]

  • Removed ginga plugin from core package and moved it to a separate repository at https://github.com/ejeschke/glue-ginga.

  • Make it possible to define a default index for DataComboHelper - this makes it possible for viewers to have three DataComboHelper and ensure that they default to different attributes. [#1163]

  • Deal properly with adding Subset objects to DataComboHelper. [#1163]

  • Added the ability to export data and subset from the data collection view via contextual menus. It was previously possible to export only the mask itself, and only to FITS files, but the framework for exporting data/subsets has now been generalized.

  • When hiding layers in the RGB image viewer, make sure the current layer changes to be a visible one if possible.

  • Avoid merging IDs when creating identity links. The previous behavior of merging was good for performance but made it impossible to undo the linking by un-glueing. Derived components created by links are now hidden by default. Finally, ComponentID objects now hold a reference to the first parent data they are used in. [#1189]

  • Added a decorator that can be used to avoid circular calling of methods (can occur when dealing with callbacks). [#1207]

  • Drop support for IPython 3.x and below, and make IPython and qtconsole into required dependencies. [#1145]

  • Added new classes that can be used to hold the state of e.g. viewers and other objects. These classes allow callbacks to be attached to various properties, and can be used to define logical relations between different attributes in a GUI-independent way.

  • Fix selections when using Matplotlib 2.x, PyQt5 and a retina display. [#1236]

  • Updated ComponentIDComboHelper to no longer store (cid, data) as the userData but instead just the cid (the data is now accessible via cid.parent). [#1212]

v0.9.2 (unreleased)

  • Avoid duplicate toolbar in dendrogram viewer. [#1213, #1237]

  • Fixed bug that caused the contrast to change for the incorrect layer in the RGB image viewer.

  • Fixed bug that caused coordinate information to be lost when merging datasets. The original behavior of keeping the coordinate information from the first dataset has been restored. [#1186]

  • Fix significant performance bottlenecks with WCS coordinate conversions. [#1185]

  • Fix error when changing the contrast radio button the RGB image viewer mode, and also fix bugs with setting the range of values manually. [#1187]

  • Fix a bug that caused coordinate axis labels to be lost during merging. [#1195]

v0.9.1 (2016-11-01)

  • Fixed loading of session files made with earlier versions of glue that contained selections made in 3D viewers. [#1160]

  • Fixed plotting of fit on spectrum to make sure that the two are properly aligned. [#1158]

  • Made it possible to now create InequalitySubsetStates for categorical components using e.g. d.id['a'] == 'string'. [#1153]

  • Fixed a bug that caused selections to not propagate properly between linked images and cubes. [#1144]

  • Make last interval of faceted subsets inclusive so as to make sure all values in the faceted subset range end up in a subset. [#1154]

v0.9.0 (2016-10-10)

  • Fix serialization of celestial coordinate link functions. Classes inheriting from MultiLink should now call MultiLink.init with individual components (not grouped into left/right) then the create_links method with the components separated into left/right and the methods for forward/backward transformation. The original behavior can be retained by using the multi_link function instead of the MultiLink class. [#1139]

  • Improve support for spectral cubes. [#1075]

  • Allow link functions/helpers to define a category using the category= argument (which defaults to General), and make it possible to filter by category in the link editor. [#1141]

  • Only show the 'waiting' cursor when glue is doing something. [#1097]

  • Make sure that the scatter layer artist style editor is shown when overplotting a scatter plot on top of an image. [#1134]

  • Data viewers can now make layer_style_widget_cls a dictionary in cases where multiple layer artist types are supported. [#1134]

  • Fix compatibility of test suite with pytest 3.x. [#1116]

  • Updated bundled version of WCSAxes to v0.9. [#1089]

  • Fix compatibility with pre-releases of Matplotlib 2.0. [#1115]

  • Implement new widget with better control over exporting to Plotly. The preference pane for Plotly export has now been removed in favor of this new way to set the options. [#1057]

  • Renamed the ComponentIDComboHelper and ManualDataComboHelper append methods to append_data and the remove methods to remove_data, and added a new ComponentIDComboHelper.set_multiple_data method. [#1060]

  • Fixed reading of units from FITS and VO tables, and display units in table viewer. [#1135, #1137]

  • Make use of the QtPy package to deal with differences between PyQt4, PyQt5, and PySide, instead of the custom qt-helpers package. The glue.external.qt package is now deprecated. The get_qapp and load_ui functions are now available in glue.utils.qt. [#1018, #1074, #1077, #1078, #1081]

  • Avoid raising a (harmless) error when selecting a region in between two categorical components.

  • Added a new Data method, update_values_from_data, that can be used to replicate components from one dataset into another. [#1112]

  • Refactored code related to toolbars in order to make it easier to define toolbars and toolbar modes that aren't Matplotlib-specific. [#1085, #1120]

  • Added a new table viewer. [#1084, #1123]

  • Fix saving/loading of categorical components. [#1084]

  • Make it possible for tools to define a status bar message. [#1084]

  • Added a command-line option, --no-maximized, that prevents glue from opening up with the application window maximized. [#1093, #1126]

  • When opening multiple files in one go, if one of the files fails to read, the error will now indicate which file failed. [#1104]

  • Fixed a bug that caused new subset colors to incorrectly start from the start of the color cycle after loading a session. [#1055]

  • Fixed a bug that caused the functionality to execute scripts (glue -x) to not work in Python 3. [#1101, #1114]

  • The minimum supported version of Astropy is now 1.0, and the minimum supported version of IPython is now 1.0. [#1076]

  • Show world coordinates and units in the cube slicer. [#1059, #1068]

  • Fix errors that occurred when selecting categorical data. [#1069]

  • Added experimental support for joining on multiple keys in join_on_key. [#974]

  • Fix compatibility with the latest version of ginga. [#1063]

v0.8.2 (2016-07-06)

  • Implement missing MaskSubsetState.copy. [#1033]

  • Ensure that failing data factory identifier functions are skipped. [#1029]

  • The naming of pixel axes is now more consistent between data with 3 or fewer dimensions, and data with more than 3 dimensions. The naming is now always Pixel Axis ? where ? is the index of the array, and for datasets with 1 to 3 dimensions, we add a suffix e.g. [x] to indicate the traditional axes. [#1029]

  • Implemented a number of performance improvements, including for: the check of whether points are in polygon (points_inside_poly), the selection of polygonal regions in multi-dimentional cubes when the selections are along pixel axes, the selection of points in scatter plots with one or two categorical components for rectangular, circular, and polygonal regions. [#1029]

  • Fix a bug that caused multiple custom viewer classes to not work properly if the user did not override _custom_functions (which was private). [#810]

  • Make sure histograms are updated if only the attribute changes and the limits and number of bins stay the same. [#1012]

  • Fix a bug on Windows that caused drag and dropping files onto the glue application to not work. [#1007]

  • Fix compatibility with PyQt5. [#1015]

  • Fix a bug that caused ComponentIDComboHelper to not take into account the numeric and categorical options in init. [#1014]

  • Fix a bug that caused saving of scatter plots to SVG files to crash. [#984]

v0.8.1 (2016-05-25)

  • Fixed a bug in the memoize function that caused selections using ElementSubsetState to fail when using views on the data. [#1004]

  • Explicitly set the icon size for the slicing playback controls to avoid issues when using a mix of retina and non-retina displays. [#1005]

  • Fixed a bug that caused add_datasets to crash if datasets was a list of lists of data, which is possible if a data factory returns more than one data object. [#1006]

v0.8 (2016-05-23)

  • Add support for circular and polygonal spectrum extraction. [#994, #1003]

  • Fix compatibility with latest developer version of Numpy which does not allow non-integer indices for arrays. [#1002]

  • Added an option to control whether warnings are shown when passing large data objects to viewers. [#999]

v0.7.3 (2016-05-04)

  • Remove icons for actions that appear in contextual menus, since these appear too large due to a Qt bug. [#911]

  • Add missing find_spec for import hook, to avoid issues when trying to set colormap. [#930]

  • Ignore extra dimensions in WCS (for instance, if the data is 3D and the header is 4D, ignore the 4th dimension in the WCS). [#935]

  • Fix a bug that caused the merge window to appear multiple times, make sure that all components named PRIMARY get renamed after merging, and make sure that the merge mechanism is also triggered when opening datasets from the command-line. [#936]

  • Make sure main window title is set. [#914]

  • Fix issue with FITS files that are missing an END card. [#915]

  • Fix a bug that caused values in exponential notation in text fields to lose a trailing zero (e.g. 1.000e+10 would become 1.000e+1). [#925]

v0.7.1 (2016-03-30)

  • Fix issue with small screens and layer and viewer options by adding scrollbars. [#902]

  • Fixed a failure due to a missing Qt import in glue.core.roi. [#901]
