<p>I'm really going to have to agree with @whuber here. I think asking graphic designers who lack much statistical knowledge is to court danger.  (Although I will acknowledge that I don't know anything about the SE site, and they may have contributors with statistical expertise.)  </p>

<p>What I did want to add is that such a question (albeit not yours, I just checked) may do well on <a href="https://stackoverflow.com/">Stack Overflow</a>.  Here, we occasionally get questions about how to do something with software (typically in <code>R</code>, but possibly using other languages) that have little actual statistical content.  If the question is <strong>only</strong> about how to get software to do something, I think it may be best asked elsewhere.  Whereas if the bulk of the question has statistical content, and the software how-to component is the lesser half, I think it primarily belongs here.  (Since your question squarely falls in the latter category--it's not about how to get the software to do anything--I think it fits here well.)</p>
