title: Tableau Start, end, and center settings for colors in heat map
body: <p>I think I have a simple question but I can't figure it out. </p>
  
  <p>I have a measure that shows percentages. I want to use 'red-green-yellow diverging' under "edit colors" to set colors based on the following criteria: </p>
  
  <pre class="lang-none prettyprint-override"><code>0%-100% = green; 
  100%-115% = yellow; 
  greater than 115% = red
  </code></pre>
  
  <p>This should be so simple! I can't figure out how to use the "start", "end", "center" in the 'edit colors' to achieve what I want above.</p>
