I’m trying to make a radar chart with a dark background. White index labels distract from the chart itself.
I found a thread that raised a question about customizing index labels, but the code in the answer only works with version 2.1.3 or mb close to it.
Is it possible in chart.js@3.5.1?

You need to set display to false in the ticks like so:
const options = {
type: 'radar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
borderColor: 'pink'
}]
},
options: {
scales: {
r: {
angleLines: {
display: false
},
grid: {
display: false
},
ticks: {
display: false
}
}
}
}
}
const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);<body> <canvas id="chartJSContainer" width="600" height="400"></canvas> <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.7.1/chart.js"></script> </body>
