title: How to specify axes for a pcolormesh?
body: <p>So i'm trying to plot a (125 x 1000) grid with specified values. I'm using matplotlib with pcolormesh. This is how my code looks, enzyme array just symbolic.</p>
  
  <pre><code>enzyme = np.array([125 x 1000])
  
  plt.pcolormesh(enzyme, cmap='Reds')
  plt.colorbar()
  plt.show()
  </code></pre>
  
  <p>The x-axis is my spatial resolution and my y-axis is time. My x-axis just runs from 0 to 125 and y-axis runs from 0 to 1000. But my actual problem is in hours, so I want the y-axis to show like 0hours -> 24hours per 2hours step. Something similar for the x-axis. So the grid index is not the right scale and number for my plot. How do I fix this. </p>
  
  <p>I tried already including like </p>
  
  <pre><code>pcolormesh(x, y, enzyme)
  </code></pre>
  
  <p>with x and y a 1D array, but these have to match the length of my enzyme grid and i have way too many datapoints to put on the x- and y- axis.</p>
