seaborn v0.9.1 Release Notes
Release Date: 2020-01-24 // about 4 years ago-
๐ This is a minor release with a number of bug fixes and adaptations to changes in seaborn's dependencies. There are also several new features.
๐ This is the final version of seaborn that will support Python 2.7 or 3.5.
๐ New features
- Added more control over the arrangement of the elements drawn by
clustermap
with the{dendrogram,colors}_ratio
andcbar_pos
parameters. Additionally, the default organization and scaling with different figure sizes has been improved. - โ Added the
corner
option toPairGrid
andpairplot
to make a grid without the upper triangle of bivariate axes. - โ Added the ability to seed the random number generator for the bootstrap used to define error bars in several plots. Relevant functions now have a
seed
parameter, which can take either fixed seed (typically anint
) or a numpy random number generator object (either the newernumpy.random.Generator
or the oldernumpy.random.mtrand.RandomState
). - Generalized the idea of "diagonal" axes in
PairGrid
to any axes that share an x and y variable. - 0๏ธโฃ In
PairGrid
, thehue
variable is now excluded from the default list of variables that make up the rows and columns of the grid. - ๐ฆ Exposed the
layout_pad
parameter inPairGrid
and set a smaller default than what matptlotlib sets for more efficient use of space in dense grids. - ๐ It is now possible to force a categorical interpretation of the
hue
varaible in a relational plot by passing the name of a categorical palette (e.g."deep"
, or"Set2"
). This complements the (previously supported) option of passig a list/dict of colors. - โ Added the
tree_kws
parameter toclustermap
to control the properties of the lines in the dendrogram. - โ Added the ability to pass hierarchical label names to the
FacetGrid
legend, which also fixes a bug inrelplot
when the same label appeared in diffent semantics. - ๐ Improved support for grouping observations based on pandas index information in categorical plots.
๐ Bug fixes and adaptations
- โ Avoided an error when singular data is passed to
kdeplot
, issuing a warning instead. This makespairplot
more robust. - ๐ Fixed the behavior of
dropna
inPairGrid
to properly exclude null datapoints from each plot when set toTrue
. - ๐ Fixed an issue where
regplot
could interfere with other axes in a multi-plot matplotlib figure. - Semantic variables with a
category
data type will always be treated as categorical in relational plots. - โ Avoided a warning about color specifications that arose from
boxenplot
on newer matplotlibs. - 0๏ธโฃ Adapted to a change in how matplotlib scales axis margins, which caused multiple calls to
regplot
withtruncate=False
to progressively expand the x axis limits. Because there are currently limitations on how autoscaling works in matplotlib, the default value fortruncate
in seaborn has also been changed toTrue
. - Relational plots no longer error when hue/size data are inferred to be numeric but stored with a string datatype.
- Relational plots now consider semantics with only a single value that can be interpreted as boolean (0 or 1) to be categorical, not numeric.
- Relational plots now handle list or dict specifications for
sizes
correctly. - ๐ Fixed an issue in
pointplot
where missing levels of a hue variable would cause an exception after a recent update in matplotlib. - ๐ Fixed a bug when setting the rotation of x tick labels on a
FacetGrid
. - ๐ Fixed a bug where values would be excluded from categorical plots when only one variable was a pandas
Series
with a non-default index. - Fixed a bug when using
Series
objects as arguments forx_partial
ory_partial
inregplot
. - ๐ Fixed a bug when passing a
norm
object and using color annotations inclustermap
. - ๐ Fixed a bug where annotations were not rearranged to match the clustering in
clustermap
. - ๐ Fixed a bug when trying to call
set
while specifying a list of colors for the palette. - ๐ Fixed a bug when resetting the color code short-hands to the matplotlib default.
- Avoided errors from stricter type checking in upcoming
numpy
changes. - โ Avoided error/warning in
lineplot
when plotting categoricals with empty levels. - ๐ Allowed
colors
to be passed through to a bivariatekdeplot
. - Standardized the output format of custom color palette functions.
- ๐ Fixed a bug where legends for numerical variables in a relational plot could show a surprisingly large number of decimal places.
- ๐ Improved robustness to missing values in distribution plots.
- Made it possible to specify the location of the
FacetGrid
legend using matplotlib keyword arguments.
- Added more control over the arrangement of the elements drawn by
