  <p>From the picture, you can see how followers statistics looks on <a href="http://minter.io" rel="nofollow noreferrer">minter.io</a></p>
  
  <p>The only way how I imagine I would count the followers change: I would download the list of all he followers every day by the Instagram API to my DB. And after having this history already can calculate any change.</p>
  
  <p>But on <a href="http://minter.io" rel="nofollow noreferrer">minter.io</a> you can have such a graphics after few minutes after registration... How???</p>
