// Create time series
let ts1 = new TimeSeries(1, {labelText: "Day 1"});
let ts2 = new TimeSeries(2, {labelText: "Day 2"});
let ts3 = new TimeSeries(3, {labelText: "Day 3"});

// Add data to time series
ts1.data = [
  new DataSample({color:'#FF0000', value: 20, desc:"Bob"}),
  new DataSample({color:'#BB0000', value: 30, desc:"John"}),
  new DataSample({color:'#880000', value: 10, desc:"Max"}),
  new DataSample({color:'#330000', value: 40, desc:"Ann"})
  ];
ts2.data = [
  new DataSample({color:'#0000FF', value: 10, desc:"Bob"}),
  new DataSample({color:'#0000BB', value: 50, desc:"John"}),
  new DataSample({color:'#000088', value: 20, desc:"Max"}),
  new DataSample({color:'#000033', value: 20, desc:"Ann"})
  ];

  new DataSample({color:'#00FF00', value: 10, desc:"Bob"}),
  new DataSample({color:'#00BB00', value: 40, desc:"John"}),
  new DataSample({color:'#008800', value: 15, desc:"Ann"})
  ];
  
// Find the canvas
let canvas = document.getElementById('chart');
  
// Create the chart
let options = {xAxis: {xLabel:"Percentage of completion"}};
let chart = new HorizontalChart(options);
chart.addTimeSeries(ts1, ts2, ts3);
chart.streamTo(canvas);
