BackdropColor scriptable

[pacomorcillo]

I have been reading the docs and found out that backdropColor is an scriptable field within the ticks configuration ( https://www.chartjs.org/docs/latest/axes/styling.html#major-tick-configuration ), but I haven't been able to find a way to make it work. Could you please provide me with an example with a valid script returning a couple of different colors?

You need to turn showLabelBackdrop to true as well.

const options = {
  type: 'line',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
        label: '# of Votes',
        data: [12, 19, 3, 5, 2, 3],
        borderColor: 'pink'
      },
      {
        label: '# of Points',
        data: [7, 11, 5, 8, 3, 7],
        borderColor: 'orange'
      }
    ]
  },
  options: {
    scales: {
      x: {
        ticks: {
          color: 'white',
          showLabelBackdrop: true,
          backdropColor: (ctx) => (ctx.tick.label)
        }
      },
      y: {
        ticks: {
          color: 'white',
          showLabelBackdrop: true,
          backdropColor: (ctx) => (ctx.tick.value > 10 ? 'green' : 'red')
        }
      }
    }
  }
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
