            var ctx = document.getElementById( "pieChart" );
            ctx.height = 130;
            var myChart = new Chart( ctx, {
            type: 'pie',
            data: {
            datasets: [ {   
            data: [ 40, 20, 10, 3, 7, 15, 4, 52 ],
            backgroundColor: [
            "rgba(0,128,128)",
            "rgba(255,20,147)",
            "rgba(0,0,128)",
            "rgba(0,128,0)",
            "rgba(128,0,0)",
            "rgba(255,0,0)",
            "rgba(218,112,214)",

            "rgba(0,128,128)",
            "rgba(255,20,147)",
            "rgba(0,0,128)",
            "rgba(0,128,0)",
            "rgba(128,0,0)",
            "rgba(255,0,0)",
            "rgba(218,112,214)",
            "rgba(70,130,180)"
            ]
            } ],
            labels: [
            "Open",
            "On-Hold (Need Spares)",
            "In-Process",
            "Closed",
            "Re-Open",
            "On-Hold (Condemnation)",
            "On-Hold (For Decision)",
            "On-Hold (For Revision)"
            ]
            },
            options: {
            responsive: true,
                legend: {
                position: 'left',     
                    labels: {
                        fontSize:17,  
                    }
                }
            }

            } );
            /////////////Pie chart END here//////////////////////////////

        } )( jQuery );

Now I need to change the font size and the color of text(data) displaying inside each slice of pie chart. Any help ?

P.s: I am using chart.js v2.7.2

chartschart.jspie-chart

If you want to change font family then you can do like this:

add font-family e.g adding 'Josefin Sans' font family

<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Josefin+Sans">

and then mention family: 'Josefin Sans' in the font JSON object. like this:-

plugins: {
      datalabels: {
        color: #ffffff,
        formatter: function (value) {
          return Math.round(value) + '%';
        },
        font: {
          weight: 'bold',
          size: 16,
          family: 'Josefin Sans',
        }
      }
}

To change the color for each data set you can use

{
   data: {
datasets: [
{
  datalabels: {
    labels: {
      value: {
        color: 'green'
      }
    }
  }
}]
}
