With the new upcomming release of version 3 you can do this with the setActive elements.

var options = {
  type: 'bar',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        borderWidth: 1,
        hoverBackgroundColor: 'green',
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        borderWidth: 1,
        hoverBackgroundColor: 'red',
      }
    ]
  },
  options: {
    scales: {}
  }
}

var ctx = document.getElementById('chartJSContainer').getContext('2d');
const chart = new Chart(ctx, options);
chart.setActiveElements([{
  datasetIndex: 0,
  index: 1,
}, {
  datasetIndex: 1,
  index: 1,
}]);
