seaborn.clustermap(data, pivot_kws=None, method='average', metric='euclidean', z_score=None, standard_scale=None, figsize=None, cbar_kws=None, row_cluster=True, col_cluster=True, row_linkage=None, col_linkage=None, row_colors=None, col_colors=None, mask=None, **kwargs)

Plot a matrix dataset as a hierarchically-clustered heatmap.

参数:data:2D array-like

Rectangular data for clustering. Cannot contain NAs.

pivot_kws:dict, optional

If <cite>data</cite> is a tidy dataframe, can provide keyword arguments for pivot to create a rectangular dataframe.

method:str, optional

Linkage method to use for calculating clusters. See scipy.cluster.hierarchy.linkage documentation for more information:

metric:str, optional

Distance metric to use for the data. See scipy.spatial.distance.pdist documentation for more options To use different metrics (or methods) for rows and columns, you may construct each linkage matrix yourself and provide them as {row,col}_linkage.

z_score:int or None, optional

Either 0 (rows) or 1 (columns). Whether or not to calculate z-scores for the rows or the columns. Z scores are: z = (x - mean)/std, so values in each row (column) will get the mean of the row (column) subtracted, then divided by the standard deviation of the row (column). This ensures that each row (column) has mean of 0 and variance of 1.

standard_scale:int or None, optional

Either 0 (rows) or 1 (columns). Whether or not to standardize that dimension, meaning for each row or column, subtract the minimum and divide each by its maximum.

figsize: tuple of two ints, optional

Size of the figure to create.

cbar_kws:dict, optional

Keyword arguments to pass to cbar_kws in heatmap, e.g. to add a label to the colorbar.

{row,col}_cluster:bool, optional

If True, cluster the {rows, columns}.

{row,col}_linkage:numpy.array, optional

Precomputed linkage matrix for the rows or columns. See scipy.cluster.hierarchy.linkage for specific formats.

{row,col}_colors:list-like or pandas DataFrame/Series, optional

List of colors to label for either the rows or columns. Useful to evaluate whether samples within a group are clustered together. Can use nested lists or DataFrame for multiple color levels of labeling. If given as a DataFrame or Series, labels for the colors are extracted from the DataFrames column names or from the name of the Series. DataFrame/Series colors are also matched to the data by their index, ensuring colors are drawn in the correct order.

mask:boolean array or DataFrame, optional

If passed, data will not be shown in cells where mask is True. Cells with missing values are automatically masked. Only used for visualizing, not for calculating.

kwargs:other keyword arguments

All other keyword arguments are passed to sns.heatmap


A ClusterGrid instance.


The returned object has a savefig method that should be used if you want to save the figure object without clipping the dendrograms.

To access the reordered row indices, use: clustergrid.dendrogram_row.reordered_ind

Column indices, use: clustergrid.dendrogram_col.reordered_ind


Plot a clustered heatmap:

>>> import seaborn as sns; sns.set(color_codes=True)
>>> iris = sns.load_dataset("iris")
>>> species = iris.pop("species")
>>> g = sns.clustermap(iris)

Use a different similarity metric:

>>> g = sns.clustermap(iris, metric="correlation")

Use a different clustering method:

>>> g = sns.clustermap(iris, method="single")

Use a different colormap and ignore outliers in colormap limits:

>>> g = sns.clustermap(iris, cmap="mako", robust=True)

Change the size of the figure:

>>> g = sns.clustermap(iris, figsize=(6, 7))

Plot one of the axes in its original organization:

>>> g = sns.clustermap(iris, col_cluster=False)

Add colored labels:

>>> lut = dict(zip(species.unique(), "rbg"))
>>> row_colors =
>>> g = sns.clustermap(iris, row_colors=row_colors)

Standardize the data within the columns:

>>> g = sns.clustermap(iris, standard_scale=1)

Normalize the data within the rows:

>>> g = sns.clustermap(iris, z_score=0)
