title: Chart.js: Set different options to datasets
body: <p>BACKGROUND</p>
  
  <p>I would like to achieve as shown in the image below using Chartjs Lines chart. Two lines, one with dots and one without dots.
  I think a solution to this would be to set different options properties to the two datasets (lines).</p>
  
  <p>PROBLEM</p>
  
  <p>Chart datasets options is set globally for the whole chart. I don´t manage to set different options for the two datasets.</p>
