title: Generate different bell curves in php with small data
body: <p>I would like to be able to generate these bellcurves from very little data:</p>
  
  <p><img src="https://i.stack.imgur.com/NKs8n.png" alt="bell cuves"></p>
  
  <p>I'm looking for a function in php that would give me the data generated by these bell curves. I don't know yet what I'm going to use to display them, but I need the data first.</p>
  
  <p>I'm not very good at math, I've tried creating some normal distribution, but there isn't an easy way to say: "I want a thin bell curve" or "I want a large one".</p>
  
  <p>Maybe using the arguments that are on top of the right side of the picture above might be cool.</p>
  
  <p>Would someone know how I can reproduce the datapoints of these graphs in PHP ?</p>
  
  <p>Thank you!</p>
