title: Confusion Matrix font size
body: <p>I have a Confusion Matrix with really small sized numbers but I can't find a way to change them.</p>
  <pre><code>from sklearn.metrics import confusion_matrix
  cm = confusion_matrix(y_test, rf_predictions)
  ax = plt.subplot()
  sns.set(font_scale=3.0) #edited as suggested
  sns.heatmap(cm, annot=True, ax=ax, cmap=&quot;Blues&quot;, fmt=&quot;g&quot;);  # annot=True to annotate cells
  
  # labels, title and ticks
  ax.set_xlabel('Predicted labels');
  ax.set_ylabel('Observed labels');
  ax.set_title('Confusion Matrix');
  ax.xaxis.set_ticklabels(['False', 'True']);
  ax.yaxis.set_ticklabels(['Flase', 'True']);
  plt.show()
  </code></pre>
  <p>thats the code I am using and the pic I get looks like:

  <p>I would not mind changing the numbers of the classification by hand but I dont really want to do it for the <em><strong>labels</strong></em> aswell.</p>
  <h1>EDIT: Figures are bigger now but the labels stay very small</h1>
  <p>Cheers</p>
