title: Changing the size of labels of plots in python
body: <p>I am using <a href="https://getdist.readthedocs.io/en/latest/plot_gallery.html" rel="nofollow noreferrer">GetDist</a> for plotting contours in <code>jupyter</code>. I am wondering how to change the size of numbers in axes and labels of parameters.
  There are some lines in the code containing labels as follows:</p>
  
  <pre><code>a,b,c = np.genfromtxt('data/data.txt',unpack=True)
  names = ['H','M','z']
  labels =  ['H','M','z']
  samples0 = MCSamples(samples=[a,b,c],names = names, labels = labels)
  g.triangle_plot([samples0],['H','M','z'],legend_labels=['Summation of data'], legend_loc='upper right',filled=True)
  </code></pre>
  
  <p>The problem is when the number of parameter goes up, the plot should be smaller to placed in a printed paper and then we cannot see numbers and parameters' labels.</p>
  
  <p>Thank you</p>
