You need to do two things.
- To show the 0 tick add this to your
options.scale
object:
ticks: {
beginAtZero: true,
min: -0.001,
}
Note that if you set min
at zero it will not work. This is how the radar tick engine works.
- To add an offset to the label override the tick render callback inside the same object, like this:
ticks: {
callback: (value) => `${value} `,
}
Note the extra spaces at the end. This is the padding. See the sample below
var options = {
responsive: false,
maintainAspectRatio: true,
scale: {
ticks: {
beginAtZero: true,
callback: (value) => `${value} `,
min: -0.001,
max: 5
}
}
};
var dataLiteracy = {
labels: [
"1", "2", "3", "4", "5"
],
datasets: [{
label: "Literacy",
backgroundColor: "rgba(179,181,198,0.2)",
borderColor: "rgba(179,181,198,1)",
pointBackgroundColor: "rgba(179,181,198,1)",
pointBorderColor: "#fff",
pointHoverBackgroundColor: "#fff",
pointHoverBorderColor: "rgba(179,181,198,1)",
data: [
2, 3, 4, 1, 2
]
}]
};
var ctx = document.getElementById("canvas");
var myRadarChart = new Chart(ctx, {
type: 'radar',
data: dataLiteracy,
options: options
});

Try this in the chart options:
ticks: {
callback: (value) => {
return '${value}';
},
