enter image description hereI'm trying to plot a chart as shown in the screen capture and I would like to shift the y-axis to the center of the x axis using existing charting fw like chart.js. Done a search but can't really find any answers. Chart

  • Please post the code on what you have tried. – Sasi Kumar M Jul 01 '19 at 13:01
  • I used a demo line chart. Possible values for position of axis are : 'top', 'left', 'bottom', 'right'. There is no config to set it to the center so I'm asking if anyone has experience to centre it – DanialChan Jul 01 '19 at 13:08

You can use the position option in the scale config and set it to 'center' like so:

const options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        borderColor: 'pink'
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        borderColor: 'orange'
      }
    ]
  },
  options: {
    scales: {
      y: {
        position: 'center'
      }
    }
  }
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
