  <dc:description>This is a major release from 0.4. Highlights include new functions for plotting heatmaps, possibly while applying clustering algorithms to discover structured relationships. These functions are complemented by new custom colormap functions and a full set of IPython widgets that allow interactive selection of colormap parameters. The palette tutorial has been rewritten to cover these new tools and more generally provide guidance on how to use color in visualizations. There are also a number of smaller changes and bugfixes.

Plotting functions

  Added the heatmap function for visualizing a matrix of data by
color-encoding the values. See the docs for more
  Added the clustermap function for clustering and visualizing a
matrix of data, with options to label individual rows and columns by
colors. See the docs for more information. This work
was lead by Olga Botvinnik.
  lmplot and pairplot get a new keyword argument, markers. This can
be a single kind of marker or a list of different markers for each
level of the hue variable. Using different markers for different
hues should let plots be more comprehensible when reproduced to
black-and-white (i.e. when printed). See the github pull
request for examples.
  More generally, there is a new keyword argument in FacetGrid and
PairGrid, hue_kws. This similarly lets plot aesthetics vary across
the levels of the hue variable, but more flexibily. hue_kws should
be a dictionary that maps the name of keyword arguments to lists of
values that are as long as the number of levels of the hue variable.
  The argument subplot_kws has been added to FacetGrid. This
allows for faceted plots with custom projections, including maps

Color palettes

  Added two new functions to create custom color palettes. For
sequential palettes, you can use the light_palette function, which
takes a seed color and creates a ramp from a very light, desaturated
variant of it. For diverging palettes, you can use the
diverging_palette function to create a balanced ramp between two
endpoints to a light or dark midpoint. See the
palette tutorial &lt;palette_tutorial&gt; for more information.
  Added the ability to specify the seed color for light_palette and
dark_palette as a tuple of husl or hls space values or as a
named xkcd color. The interpretation of the seed color is now
provided by the new input parameter to these functions.
  Added several new interactive palette widgets:
choose_colorbrewer_palette, choose_light_palette,
choose_dark_palette, and choose_diverging_palette. For
consistency, renamed the cubehelix widget to
choose_cubehelix_palette (and fixed a bug where the cubehelix
palette was reversed). These functions also now return either a
color palette list or a matplotlib colormap when called, and that
object will be live-updated as you play with the widget. This should
make it easy to iterate over a plot until you find a good
representation for the data. See the Github pull
request or this
notebook (download it to use the
widgets) for more
  Overhauled the color palette tutorial to
organize the discussion by class of color palette and provide more
motivation behind the various choices one might make when choosing
colors for their data.

Bug fixes

  Fixed a bug in PairGrid that gave incorrect results (or a crash)
when the input DataFrame has a non-default index.
  Fixed a bug in PairGrid where passing columns with a date-like
datatype raised an exception.
  Fixed a bug where lmplot would show a legend when the hue variable
was also used on either the rows or columns (making the legend
  Worked around a matplotlib bug that was forcing outliers in boxplot
to appear as blue.
  kdeplot now accepts pandas Series for the data and data2
  Using a non-default correlation method in corrplot now implies
sig_stars=False as the permutation test used to significance
values for the correlations uses a pearson metric.
  Removed pdf.fonttype from the style definitions, as the value used
in version 0.4 resulted in very large PDF files.
