[Solved]-How to Increase the label font size and decrease the size of my pie using chart.js?-Chart.js

you can add this:

options: {
    **maintainaspectratio : true**, // make the pie small
     legend: {
        display: true,
        labels: {
              **fontsize: 15** //change the size of the labels
        }
    }

}

good luck

  options: {
        legend: {
            display: true,
            labels: {
                fontcolor: 'rgb(255, 99, 132)'
            }

}
