VistasIs there any way to change the font size of labels in bar chart in Chart.js v3?
It creates a bar graph that extends horizontally.
CodeSandBox
The font size of labels such as Bach and Morzart is small and I want to increase it. Could you please tell me how to change the font size of labels?
<div class="chartWrap">
<canvas id="chart"></canvas>
</div>
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<script>
const labels = ["Bach", "Mozart", "Ravel", "Chopin", "Beethoven"];
const data = {
labels: labels,
datasets: [
{
data: [9, 10, 7, 8, 8],
backgroundColor: "rgba(0, 0, 0, 0.5)"
}
]
};
const options = {
responsive: true,
indexAxis: "y",
plugins: {
legend: {
display: false
}
}
};
const config = {
type: "bar",
data: data,
options: options
};
const ctx = document.getElementById("chart").getContext("2d");
new Chart(ctx, config);
</script>
Looking at the many examples of Chart.js, I know that the font size should be specified in options > scales, but I didn't know what to type under scales.

Add this into the options.
scales: {
y: {
ticks: {
font: {
size: 30,
}
}
}
}
