I believe you can get the result you want by using the max
parameter on the ticks
configuration of the x axes.
By using 2 different x axes with different maximums you can label the bars differently from how they’re drawn. Resulting in labeling the marks in between the bars without drawing an extra “empty” bar.
var ctx = document.getElementById("myChart").getContext('2d');
var dataValues = [12, 19, 3, 5];
var dataLabels = [0, 1, 2, 3, 4];
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: dataLabels,
datasets: [{
label: 'Group A',
data: dataValues,
backgroundColor: 'rgba(255, 99, 132, 1)',
}]
},
options: {
scales: {
xAxes: [{
display: false,
barPercentage: 1.3,
ticks: {
max: 3,
}
}, {
display: true,
ticks: {
autoSkip: false,
max: 4,
}
}],
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});
canvas { max-width: 200px; }
