Hide points in ChartJS LineGraph

问题

Originally I set the fill color for each point to be completely transparent. If I run my mouse over the graph, the points pop up. I want to hide all points so that the line graph is smooth.

You can achieve this by setting point's radius property in configuration options as follows:

var chartConfig = {
            type: 'line',
            options: {
                elements: {
                    point:{
                        radius: 0
                    }
                }
            }
        }

Tooltips for the points will also gone off.

You can set the pointRadius to zero.

var myChart = new Chart(
    ctx, {
        type: 'line',
        data: {
            labels: [...]
            datasets: [
              {
                data: [...],
                pointRadius: 0,  # <<< Here.
              }
            ]
        },
        options: {}
    })
