[AngeloCG97]

Hi, i worked with radar the react-chart-2, i need change font size the labels selected with red on this image. But i can´t do

I have tried some solutions like these but they don't work

Chart.defaults.font.size = 20

plugins: {
          legend: {
            display: showLabel,
            item: {
              label: {
                font: {
                  size: 20
                }
              }
            }
          },
          title: {
            display: true,
            text: 'Custom Chart Title'
          },
          subtitle: {
            display: true,
            text: 'Custom Chart Subtitle',
            font: {
              size: 20
            }
          },
          datalabels: {
            color: '#ffccff',
            labels: {
              font: {
                size: 20
              },
              value: {},
              title: {
                color: '#ccffcc'
              }
            }
          }
        },

I would appreciate the help

I have a solution on this link https://jsfiddle.net/Leelenaleee/qv6hkxLf/3/

The property is

scales: {
          r: {
               pointLabels: {
                   fontColor: '#443F5B',
                   font: {
                       size: 12
                    }
                }
            }
}
