<p>Unless I'm reading your question wrong, <a href="https://stats.meta.stackexchange.com/questions/4757/how-do-i-find-what-percent-of-my-points-come-from-which-tags#comment13303_4757">amoeba's comment</a> pretty much answers it:</p>

  <p>Something like that? <a href="https://stats.stackexchange.com/users/22452/engrstudent?tab=tags">https://stats.stackexchange.com/users/22452/engrstudent?tab=tags</a></p>

<p>The only thing left there would be actually converting that into percentages. <a href="http://data.stackexchange.com/stats/query/660948/percentage-of-users-total-rep-coming-from-each-tag?UserId=22452" rel="nofollow noreferrer">I wrote a query for that</a>. Note that, <a href="https://stats.meta.stackexchange.com/questions/4757/how-do-i-find-what-percent-of-my-points-come-from-which-tags#comment13304_4757">as Glen_b puts it</a>:</p>

<blockquote>
  <p>Each tag gets <em>all</em> the points of any of your (non-wiki) answers it's in. The total points that accrue to your tags will exceed your total reputation.</p>
</blockquote>

<p>Which means that percentages are gonna exceed 100%, and total rep is gonna exceed the actual rep (as explained in the query's description).</p>

<p>One final note: my SQL-fu is not at ninja level, so let me know if you spot something completely off in the query or numbers it generates.</p>
