title: How to deal with the colorbar axis space in matplotlib subplots
body: <p>I am plotting seven different parameters over four seasons, as shown in below image. but on last column (<strong>Post-Monsoon</strong>) sub_plots axis compromised with colorbar axis, that is really awkward!!</p>

  <p>How to adjust colorbar without distortion of the last axis, Any remark from the community
  Thanks</p>
