title: Linking Data in multiple Charts Highcharts
body: <p>I'm new to JS charting libraries and I have started working with Highcharts. I have a scenario like this and I couldn't figure out a way to do it.</p>
  
  <p>Scenario: I have a bar chart showing the employee turn over by years. Also, I have a  separate pie chart showing different department's percentage of turnover. But when I click on one year (one column on bar graph ) the pie chart should get changed to show the employee turnover by different departments only for that selected year.</p>
  
  <p>I searched in different places and I couldn't get a solution for this. Can someone help me with this?</p>
