title: Custom spacing between groups in boxplots
body: <p>There's a <a href="https://stackoverflow.com/questions/49036808/distance-between-box-plots-with-unequal-samples">thread</a> on stackoverflow with exactly the same question, but it is for Matlab. However, I'm using matplotlib and I don't know how to proceed. Basically, I have a number of boxplots, but I want to separate them like this (copied shamelessly from the thread above):</p>

  <p>How can I go about this? There's a suggestion to put an invisible boxplot in between the two groups, but I don't know how to make the tick (not just the label) vanish only for that value.</p>
