title: In Stata, how can I change color of the coefplot's gridlines?
body: <p>I'm trying to change the color of gridlines in a Stata's graph. The usual method works fine in builtin graphs</p>
  
  <pre><code>sysuse auto
  hist mpg, ylabel(, grid glcolor(green))
  </code></pre>
  
  <p>However, it fails when I try to do the same with <code>coefplot</code> graph where the grid has default blueish color:</p>
  
  <pre><code>reg price mpg headroom trunk length turn
  coefplot, drop(_cons) xline(0) ylabel(, grid glcolor(green)) 
  </code></pre>
  
  <p>Any ideas how to change that?</p>
