[javascript] Chart.js v2 - hiding grid lines

I am using Chart.js v2 to draw a simple line chart. Everything looks fine, except there are grid lines that I don't want:

The documentation for Line Chart is here: https://nnnick.github.io/Chart.js/docs-v2/#line-chart, but I can't find anything about hiding those "Grid Lines".

How can I remove the grid lines?

options: {
    scales: {
        xAxes: [{
            gridLines: {
                drawOnChartArea: false
            }
        }],
        yAxes: [{
            gridLines: {
                drawOnChartArea: false
            }
        }]
    }
}

Please refer to the official documentation:

https://www.chartjs.org/docs/latest/axes/styling.html#grid-line-configuration

Below code changes would hide the gridLines:

        gridLines: {
            display:false
        }

OK, nevermind.. I found the trick:

    scales: {
      yAxes: [
        {
          gridLines: {
                lineWidth: 0
            }
        }
      ]
    }

The code below removes remove grid lines from chart area only not the ones in x&y axis labels

Chart.defaults.scale.gridLines.drawOnChartArea = false;

If you want to hide gridlines but want to show yAxes, you can set:

yAxes: [{...
         gridLines: {
                        drawBorder: true,
                        display: false
                    }
       }]

If you want them gone by default, you can set:

Chart.defaults.scale.gridLines.display = false;
