title: How can I solve my dimension issue with Python pcolor?
body: <p>I have a 3 lists and I would like to make a pcolor plot. </p>
  
  <p>ccplot = plt.pcolor(a,b, c, vmin=np.min(c), vmax=np.max(c))</p>
  
  <p>the shape of a and b are: (108,)</p>
  
  <p>The problem is:</p>
  
  <p>when the shape of c is (216,) I get the error: </p>
  
  <p>" ValueError: not enough values to unpack (expected 2, got 1) "</p>
  
  <p>and when I reshape the c to be a 2d array of the shape (10800, 2), I get the error:</p>
  
  <p>" TypeError: Dimensions of C (108, 2) are incompatible with X (108) and/or Y (108); see help(pcolor) "</p>
  
  <p>Please help me handle this pcolor plot.
  I appreciate in advance.</p>
  
  <p>regards
