title: Stacked areachart with percents values on the y axis using Charts.js and Angular 8
body: <p>I'am using Angular 8 and ng2-charts package to create a stacked areachart. I want to create a chart <a href="https://www.anychart.com/chartopedia/chart-type/percent-stacked-splinearea-chart/" rel="nofollow noreferrer">like this</a>. I tried to use min and max values to create Y axis from 0% to 100%, but it works incorrect with different data (if the sum of data for each label is greater than 100, then the graph is out of bounds). I also want to display them stacked on top of one another, but don't know how to achieve this.</p>
  
  <p>I also attach <a href="https://stackblitz.com/edit/angular-444qxy" rel="nofollow noreferrer">my code on stackblitz</a>, where I tried to wrote this.</p>
