pandas Seaborn 热图未显示所有 xticks 和 yticks

Seaborn heatmap not displaying all xticks and yticks

提问by vaibhavk

I have a pandas dataframe of shape (39, 67). When I plot it's seabornheatmap, I don't get as many labels on the X and Y axes. .get_xticklabels()method also returns only 23 labels.

我有一个形状为 (39, 67) 的Pandas数据框。当我绘制它的seaborn热图时，我在 X 和 Y 轴上没有得到那么多标签。.get_xticklabels()方法也只返回 23 个标签。

matplotlibdoesn't show any labels (only numbers) as well.

matplotlib也不显示任何标签（仅数字）。

Both these heatmaps are for the same dataframe (39, 67).

这两个热图都针对同一个数据帧 (39, 67)。

To ensure the labels are visible, you have to set the parameters xticklabels, yticklabelsto True, like so.

为确保标签可见，您必须像这样设置参数xticklabels、yticklabels至True。

import seaborn as sns 
sns.heatmap(dataframe, xticklabels=True, yticklabels=True)

Here'sthe documentation for the heatmapfunction.

这是该heatmap函数的文档。
