I'm using chart.js v3.2.0 and I want to disable the grid lines and x-axis labels. I've tried various examples from other stack overflow posts but none seem to work.

scales: {
xAxes: [{
display: false,

display: false //this will remove only the label
}
}],
yAxes: [{
display:false
}]
},
responsive: true,
maintainAspectRatio: false
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
Does anyone know how to do it?
Thanks
Chart.js v3 has multiple breaking changes, one of them is how you define the scales, it is stated in the migration guide and shown in a lot of the examples (https://www.chartjs.org/docs/3.2.1/getting-started/v3-migration.html)
You will have to change scales: { yAxes: [], xAxes: []} to scales: { y: {}, x: {}}
Working fiddle: https://jsfiddle.net/Leelenaleee/r26h71fm/2/
Hide GridLines on Both Axis -
ChartJS v2 (older version) -
scales: {
x: [
{
gridLines: {
display: false,
},
},
],
y: [
{
gridLines: {
display: false,
},
},
],
},
Newer Version ChartJS v3 -
scales: {
x: {
grid: {
display: false,
},
},
y: {
grid: {
display: false,
},
},
},

I want to align bar to left, but I didn't find anything yet! if there is only one bar its data, then it will render at the center of the chart, and I want to render it on the left!
You could add some fake entries into data.labels.
data: {
labels: ["A", "", "", ""],
Please have a look at below runnable code snippet.
new Chart("chart", {
type: "bar",
data: {
labels: ["A", "", "", ""],
datasets: [{
label: "My Dataset",
data: [1],
backgroundColor: "rgba(255, 99, 132, 0.2)",
borderColor: "rgb(255, 99, 132)",
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
min: 0,
max: 1,
stepSize: 1
},
gridLines: {
drawOnChartArea: false
}
}],
xAxes: [{
gridLines: {
drawOnChartArea: false
}
}]
}
}
});
canvas {
max-width: 200px;

I have a simple bar chart and I'm using the datalabels plugin to place labels inside each bar and at the top.
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ['One', "Two"],
datasets: [{
data: [40, .5],
backgroundColor: [
'rgba(255, 99, 132)',
'rgba(54, 162, 235)'
],
borderWidth: 1
}]
},
options: {
legend: {
display: false
},
tooltips: {
enabled: false
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
max: 40
},
}],
xAxes: [{
maxBarThickness: 50
}]
},
plugins: {
datalabels: {
display: true,
anchor: 'end',
align: 'top',
color: 'white',
offset: -30,
font: {
weight: 'bold',
size: 14
}
}
}
}
});
But sometimes, I'll have a value that doesn't allow enough room for the label. See second bar on https://jsfiddle.net/myckxLun/1/.
I want to make sure I have X amount of room for these labels. I've tried minBarLength for the Y-axis - but all this does is force the bar length to be a min pixel value and doesn't adjust the graph (i.e. the bar length is inaccurate).
Ideas on how I can fix this? Thanks!
I am working on one project where i am using Charts.js for showing charts, Here i want to show all bar values by default on top of each bar (Using bar chat), when we hover mouse on that bar it shows value, but is there any was to show that tooltip by default without hover on it
Below fiddle is the example, Here in this fiddle i want to show 60,30,40 as default on bar chart by default without taking hover on it.
Here in above screenshot i have tried to put all the tooltip as by default but as there are 3 charts are used it shows tooltip to all the charts but I want to put tooltip to only bar chart, I know it's bit tricky but there will be some way using which i can resolve my issue.
Please guide me, here is my code snipped of JS
getchart();
function getchart() {
$("#barChart").remove();
const decimals = 3;
$(".chart").append("<canvas id='barChart' width='692' height='346'></canvas>");
var ctx = document.getElementById("barChart");
Chart.pluginService.register({
beforeRender: function(chart) {
if (chart.config.options.showAllTooltips) {
chart.pluginTooltips = [];
chart.config.data.datasets.forEach(function(dataset, i) {
chart.getDatasetMeta(i).data.forEach(function(sector, j) {
console.log(chart);
chart.pluginTooltips.push(new Chart.Tooltip({
_chart: chart.chart,
_chartInstance: chart,
_data: chart.data,
_options: chart.options.tooltips,
_active: [sector]
}, chart));
});
});
}
chart.options.tooltips.enabled = false;
},
afterDraw: function(chart, easing) {
if (chart.config.options.showAllTooltips) {
if (!chart.allTooltipsOnce) {
if (easing !== 1)
return;
chart.allTooltipsOnce = true;
}
chart.options.tooltips.enabled = true;
Chart.helpers.each(chart.pluginTooltips, function(tooltip) {
tooltip.initialize();
tooltip.update();
tooltip.pivot();
tooltip.transition(easing).draw();
});
chart.options.tooltips.enabled = false;
}
}
})

I have a line chart that's created using chart.js. Everything works fine on page load, but when toggle the chart and hover to chart's corners, it shows old charts.
Also here is the live webapp that you can see the behavior.

I tried to fix with update(), destroy and clear however non of them worked.
Thanks a lot for the help,
Here is my code;
var ctx = document.getElementById("chartContainer").getContext("2d");

data: mobileData,
backgroundColor: ["rgba(255, 99, 132, 0.2)"],
borderColor: ["rgba(255, 99, 132, 1)"],
borderWidth: 1
},
{
label: "Desktop Speed Scores",
data: desktopData,
backgroundColor: ["rgba(49, 67, 129, 0.2)"],
borderColor: ["rgba(49, 67, 129, 1)"],
borderWidth: 1
}
]
},

}
}
],
yAxes: [

scaleLabel: {
display: true,

}
}
]
}
}
});
myChart.render();
const removeElements = elms => elms.forEach(el => el.remove());
removeElements(document.querySelectorAll(".progress"));
function toogleDataSeries(e) {
e.dataSeries.visible = !(
typeof e.dataSeries.visible === "undefined" || e.dataSeries.visible
);
myChart.destroy();
myChart.render();
}
}
I am using Bar chart of Chart.js which is creating unwanted spacing on left and right side. I have tried to remove that by making canvas width and height to 100% as mentioned chartjs-is-there-any-way-to-remove-blank-space-around-pie-charts here. But it's not removing in my case.
I also need to remove horizontal line below the chart. Is there any way to do so?
Here's what i tried:
//Bar Chart
var bar = document.getElementById("bar-canvas");
var barChart = new Chart(bar, {
type: 'bar',
data: {
labels: ["Jackets", "Pants", "Headwear", "Shirts", "Footwear"],
datasets: [{
label: 'Dataset 1',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'#A7E3FF',
'#A7E3FF',
'#A7E3FF',
'#A7E3FF',
'#A7E3FF'
],
borderColor: [
'#A7E3FF',
'#A7E3FF',
'#A7E3FF',
'#A7E3FF',
'#A7E3FF'
],
borderWidth: 1
},
{
label: 'Dataset 2',
data: [20, 19, 10, 52, 2, 13],
backgroundColor: [
'#FD99EE',
'#FD99EE',
'#FD99EE',
'#FD99EE',
'#FD99EE'
],
borderColor: [
'#FD99EE',
'#FD99EE',
'#FD99EE',
'#FD99EE',
'#FD99EE'
],
borderWidth: 1
}]
},
responsive: true,
options: {
legend: {
display: false
},
tooltips: {
callbacks: {
label: function(tooltipItem) {
return tooltipItem.yLabel;
}
}
},
scales: {
xAxes: [{
stacked: true,
gridLines: {
color: "rgba(0, 0, 0, 0)"
},
ticks: {
fontColor: '#0071bc'
},
barThickness: 110
}],
yAxes: [{
stacked: true,
gridLines: {
color: "rgba(0, 0, 0, 0)"
},
scaleLabel: {
display: false
},
ticks: {
display: false
}
}
]
}
}
});

Managed to remove the bottom line, but somehow could not remove the padding, - commented an area, which removes a little bit, but then you lose the ticks (which is obviously bad)
Just adding a fiddle, hope it helps at least somehow!

..xAxes..
ticks: {
display: true, // removing this
fontColor: '#0071bc',
},
