You can add a second x-axis of type: 'linear'
as follows.
{
type: 'linear',
ticks: {
min: 0,
max: labels.length,
stepSize: 1,
callback: (v, i) => i == 0 ? '' : labels[i - 1]
}
}
Note that I use a ticks callback method in order to provide the desired tick label at given index.
Then you should also hide the grid lines and ticks of the default x-axis.
{
gridLines: {
display: false
},
ticks: {
display: false
}
}
Please take a look at below runnable sample code and see how it works.
const labels = ['4.80', '9.60', '14.40', '19.20', '24.00', '28.80'];
new Chart(document.getElementById('myChart'), {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: "My Dataset",
data: [4, 8, 5, 7, 2, 4],
backgroundColor: 'orange',
categoryPercentage: 1,
barPercentage: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}],
xAxes: [{
gridLines: {
display: false
},
ticks: {
display: false
}
},
{
type: 'linear',
ticks: {
min: 0,
max: labels.length,
stepSize: 1,
callback: (v, i) => i == 0 ? '' : labels[i - 1]
}
}
]
}
}
});

options: {
title: {
display: true,
position: 'right'
}
}
