<h1>Graphing the relation between wheels and awards for FRC
</h1>
<h4>AKA. Why programmer + reddit + matplotlib is a bad idea.
</h4>
<hr>
<p><em>2019-06-16 11:51:00 -0400
</em></p>
<br>
<p>I was scrolling through reddit the other day, and came across <a href="https://www.reddit.com/r/FRC/comments/byzv5q/i_know_what_im_doing/">this great post</a> by u/<a href="https://www.reddit.com/user/MasterQuacks/">MasterQuacks</a>.</p>
<p><img src="/assets/images/w2ainspo.jpg" alt="My insporation" /></p>
<p>I thought to myself “ha. Thats funny”, and moved on. But that thought had stuck with me.</p>
<p>So here I am, bored on a sunday afternoon, staring at the matplotlib documentation.</p>
<h2 id="my-creation">My creation</h2>
<p>In only a few lines of python, I have a program that will (badly) graph the number of awards per wheel for any team, or set of teams.</p>
<p>As always, feel free to tinker with the code. This one is not published anywhere, so if you want to share it, I would appreciate a mention.</p>
