title: Chart.js -> line chart -> multiple points with the same X
body: <p>I am using <a href="https://www.chartjs.org/" rel="nofollow noreferrer">chart.js</a> to create some charts, and I need to make line chart that have multiple entries for the same point in the X axes.</p>
  
  <p>In other words, this:
  <a href="https://i.stack.imgur.com/NbmXY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NbmXY.png" alt="enter image description here"></a></p>
  
  <p>Whatever I try, i can not create it to look like the image.
  Dose anyone know how I can manage this (with plugins or without)?</p>
