  <p>How to set distance between tick labels and axis label? I just need to enlarge distance between "Number of stars" label and corresponding tick labels. Maybe latex <code>\vspace{}</code> is working but I don't know how to implement it. <code>fig.subplots_adjust(left=)</code> is not a solution.</p>
