ChartJS - Draw chart with label by month, data by day

Question

I'd like to draw a line chart by Chartjs with data by day, but label by month.

If label is displayed by day, then there are a lot of points. So, I'd like to display label by month instead of by day. For example:

Someone could teach me how to do that?

Thank you.

Just config your xAxes->time property as:
unit: 'month'

xAxes: [{
  type: 'time',
  position: 'bottom',
  time: {
    displayFormats: {'day': 'MM/YY'},
    tooltipFormat: 'DD/MM/YY',
    unit: 'month',
   }
}],
