title: Find special chart on highcharts
body: <p>I would like to build a chart like this 
  <a href="https://i.stack.imgur.com/nStTc.png" rel="nofollow noreferrer">enter image description here</a></p>
  
  <p>Drag the red point or two blue lines on the left chart, then the chart will generate the second one on the right.
  Please advice me how to do with highcharts or other chart library. Thank you very much!</p>
