chart.js - angular chartjs line chart default options

Wondering if it is possible to have 1 configuration for all line charts that are created using chart.js Something like :

var chartOptions = new Chart.options = options: {
        responsive:true,
        maintainAspectRatio: false,
        
        legend: {
          labels:{
            fontColor : '#01c38c',
          },
          display: true
        },
        scales: {
          xAxes: [{
            type: 'time',
            time: {
              unit: 'day',
              displayFormats:{
                'day': 'MMM DD',
                'week': 'MMM DD',
                'month': 'MMM YYYY'
              },
              
            },
            gridLines :{
              display: true,
              color: 'grey',
            } 
          }],
           
      }

Then inject these options using:

this.chart.options = this.chartOptions;

I don't want to specify options for multiple charts, as they are the same. What is the best approach to this?

Thanks,

You can set global default options by using Chart.defaults.global.optionname. You will have to do this for every option so the part for your legend default options will look like this:

Chart.defaults.global.legend.labels.fontcolor = '#01c83c';
Chart.defaults.global.legend.display = true;
