如何抑制绘制树状图但仍然聚集在seaborn中?

问题描述：

我想在 seaborn 中绘制一个集群图，按行和列进行聚类.我不想绘制树状图.

I want to plot a clustermap in seaborn, clustered by both rows and columns. I do not want to draw the dendrograms.

设置 row_cluster=False 或 col_cluster=False 会移除树状图，但也会停止聚类.

Setting row_cluster=False or col_cluster=False removes the dendrograms, but also stops the clustering.

如何仍然使用 2D 聚类但抑制树状图?

这个问题提供了设置宽度的技巧树状图行数为 0.此 hack 在 seaborn 0.7.1 中不起作用.

This question provides a hack of setting the width of the dendrogram lines to 0. This hack does not work in seaborn 0.7.1.

答

答案隐藏在文档中.

让 cg 成为 Seaborn 返回的 clustermap 实例.

Let cg be the clustermap instance returned by Seaborn.

绘制聚类图后，键入以下内容以删除行树状图.

After drawing the clustermap, type the following to remove the row dendrogram.

cg.ax_row_dendrogram.set_visible(False)

如果要保留图例，请键入:

If you want to preserve the legend, type:

cg.ax_row_dendrogram.set_xlim([0,0])

这是一个 hack，但是 set_axis_off() 在 Seaborn 中似乎没有在 matplotlib 中做的那样.

This is a hack, but set_axis_off() does not seem to do in Seaborn what it does in matplotlib.
