The correct syntax for globally changing the bar categoryPercentage
is the following:
Chart.defaults.global.datasets.bar.categoryPercentage = 0.95;
And here’s a working sample:
Chart.defaults.global.datasets.bar.categoryPercentage = 0.95;
var canvas = document.getElementById('myChart');
var data = {
labels: ["A", "B", "C", "D", "E"],
datasets: [{
label: "Occurrences",
data: [3, 5, 2, 4, 6],
fill: false,
backgroundColor: ["rgba(255, 99, 132, 0.2)", "rgba(255, 159, 64, 0.2)", "rgba(255, 205, 86, 0.2)", "rgba(75, 192, 192, 0.2)", "rgba(54, 162, 235, 0.2)"],
borderColor: ["rgb(255, 99, 132)", "rgb(255, 159, 64)", "rgb(255, 205, 86)", "rgb(75, 192, 192)", "rgb(54, 162, 235)"],
borderWidth: 1
}]
};
var option = {
scales: {
yAxes:[{
ticks: {
beginAtZero: true
}
}]
}
};
var myBarChart = Chart.Bar(canvas, {
data:data,
options:option
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.3/Chart.min.js"></script>
<canvas id="myChart" width="400" height="200"></canvas>
To find out about other valid options contained in
Chart.defaults
, simply log it to the console (console.log(Chart.defaults)
) and search for the option name.

You don’t need to set it globally, I actually recommend you to set it for each chart according to documentation.
var canvas = document.getElementById('myChart');
var data = {
labels: ["A", "B", "C", "D", "E"],
datasets: [{
label: "Occurrences",
data: [3, 5, 2, 4, 6],
fill: false,
backgroundColor: ["rgba(255, 99, 132, 0.2)", "rgba(255, 159, 64, 0.2)", "rgba(255, 205, 86, 0.2)", "rgba(75, 192, 192, 0.2)", "rgba(54, 162, 235, 0.2)"],
borderColor: ["rgb(255, 99, 132)", "rgb(255, 159, 64)", "rgb(255, 205, 86)", "rgb(75, 192, 192)", "rgb(54, 162, 235)"],
borderWidth: 1
}]
};
var option = {
datasets: {
bar: {
categoryPercentage: 0.95
}
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
};
var myBarChart = Chart.Bar(canvas, {
data: data,
options: option
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.3/Chart.min.js"></script>
<canvas id="myChart" width="400" height="200"></canvas>
