I am trying to rotate the xaxis labels but the xticks function below has no effect and the labels overwrite each other

import matplotlib.pyplot as plt import seaborn as sns corrmat = X.corr() plt.xticks(rotation=90) plt.figure(figsize=(15,16)) ax = sns.heatmap(corrmat, vmin=0, vmax=1) ax.xaxis.tick_top()

Jumbled xaxis

After using suggested code changes: I get the following but I still want to increase the size of the heatmap

How to increase the size of this heatmap

setp looks to be the way to go with pyplot (inspiration from this answer). This works for me:

import matplotlib.pyplot as plt import seaborn as sns; sns.set() import numpy as np; np.random.seed(0) data = np.random.rand(10, 12) ax = sns.heatmap(data) ax.xaxis.tick_top() locs, labels = plt.xticks() plt.setp(labels, rotation=90) plt.show()

Obviously I don't have your data, hence the numpy random data, but otherwise the effect is as required:

I updated my question with your code (with some modifications). How do I increase the size of this heatmap?
