1.4.8

Misc fixes and updates

1.4.1

• Uses fast numpy loadtxt to load chains in numpy >= 1.23 (much faster than previous pandas fallback)
• Minor fixes

1.4

• GetDist GUI supports PySide 6
• Minor fixes

1.3

• Added plot_4d for 3-D colored scatter plots, with optional animation and mp4 export
• GUI updates for dark mode and dpi compatibility; copy image to clipboard
• Use numpy 1.17 Generators for random sampling
• MCSamples instances can now access parameter sample values via samples['name']
• Fixes for Cobaya chain load
• Bug fixes and updates for compatibility

1.2.0

Various small bug and version compatibility fixes.

1.1.0

• Support for plotting and gui loading chains from any hierarchy of folders given the root folder name as chain_dir
• Large speed up for analysing very long highly correlated chains (in getEffectiveSamplesGaussianKDE)
• Removed Python 2 support, updates for Python 3 (see Python2latest for Py2-compatible version)
• Fixes and updates for Cobaya chain compatibility including propagating fixed parameter values
• Removed paramgrid module (loaded from cosmomc if that is installed and configured)

1.0

• getdist.styles modules for consistently changing styles of plots and easily using default matplotlib colors. See plots.set_active_style. Styles included are "default", "tab10" (default matplotlib 2 colors) and "planck" (more complicated example).
• BoundedMaxNLocator for determining tick locations dynamically accounting for label lengths to avoid overlaps.
  Parameters axis_tick_step_groups, axis_tick_powerlimits available in settings
• Latest matplotlib compatibility (now requires 2.2+, with 3.1+ recommended). Internal changes to use gridspec and other more modern features
• Saving/loading of labels and sampler sample properties
• Cache files now in temp/cache directory by default (avoids issues with file write access at chain file location)
• Subplot layout improved; option to use constrained_layout
• plot_1d, plot_2d and plot_3d now automatically call finish_plot() when there is only one set of axes [which calls tight_layout as needed to make everything fit in the requested size)
• Options to control font size scaling, which is now applied dynamically if scaling=True (see settings)
• subplot_size_ratio parameter to change default subplot aspect ratio
• More common plot parameter defaults available from settings and hence also styles (legend_colored_text, title_limit etc.)
• getdist.plots consistently uses lower case (PEP8). Other modes still mainly use CamelCase. Old forms still work.
• Triangle plot option upper_label_right when using upper roots
• Convenience function get_axes. Many refactorings for consistent axes arguments.
• Added add_bands for plotting constraint bands
• Improved support for rotated tick labels (rotation options in settings)
• Added getEffectiveSamplesGaussianKDE_2d
• Tweaked KDE bandwidth estimation for fewer failures
• Added option to get best fit sample (getParamBestFitDict)
• Removed some deprecated features including support for old fortran GetDist plot_data files
• Significant GetDist GUI improvements (now renamed "getdist-gui"):
  • high DPI support
  • change plot settings (options menu) interactively in script view
  • Mac .app wrapper and compatibility
  • Coordinates and panning in the interactive preview page
  • Status bar shows any warnings
  • Easier changing of boolean settings in the options windows

0.3.3

• Added title_limit option for 1D and triangle plots to add parameter limit at top of each subplot
• Add markers option to triangle_plot
• Cobaya 2 compatibility
• Minor GUI fixes

0.3.1

• GetDistGUI support for python3 with PySide2
• Better support for nested sampling and uncorrelated samples via specified sample type
• Bug and doc fixes

0.3.0

Further support for Cobaya chains, and parameter aliases/renames.

Some support for scientific exponential notation for very large/small parameters in table outputs.

Improvements to triangle_plot including options for the upper triangle

Various bug fixes and updates for latest matplotlib.
