title: Understanding pcolor plots
body: <p>I'm trying to find something that helps me get an understanding of what a pcolor (Pseudocolor) plot is and how it functions. I have had it set as an example in a course I'm doing but it has little explanation as to it's use or how it functions on data.</p>
  
  <p>I've tried searching and I have found <a href="https://au.mathworks.com/help/matlab/ref/pcolor.html" rel="nofollow noreferrer">https://au.mathworks.com/help/matlab/ref/pcolor.html</a></p>
  
  <p>But that hasn't helped any further with my understanding of exactly how it functions. Does anyone know of a good tutorial or explanation they could point me to so I could read through to get a handle on what this plot actually is.</p>
