After setting up a stacked horizontal bar chart using chartjs, the x-axis cannot be hidden. I have tried numerous ways to remove it like using "display:false" and making the text transparent but to no avail. Here is what it looks like and what I want it to look like:

Thanks in advance~!
Current Chartjs code:
datasets: [
{
label: 'Example Data One',
data: [10],
backgroundColor: '#C4D156',
borderColor: "#ffffff",
borderWidth: 1.5
},
{
label: 'Example Two, etc',
data: [25],
backgroundColor: '#68A03F',
borderColor: "#ffffff",
borderWidth: 1.5
},
{
label: 'Three',
data: [55],
backgroundColor: '#2F9138',
borderColor: "#ffffff",
borderWidth: 1.5
}
]
};
},
options: {
maintainAspectRatio: false,
legend: {
display: false
},
tooltips: {
bodySpacing: 4,
xPadding: 12,
mode: "nearest",
intersect: 0,
position: "nearest"
},
responsive: true,
scales: {
yAxes: [
{stacked: true},
],
xAxes: [
{stacked: true},
{gridLines: {
display:false
}
},
]
}
}
Hiding the label/text on the axis is done with that
options: {
...
scales: {
...
xAxes: [{
ticks: {
display: false //this will remove the label/text
}
}]
}
}

I need to align horizontal bars to the right side like this
but actual result from my code is this
You could use floating bars for this:
const options = {
type: 'horizontalBar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [
[
20,
12
],
[
20,
19
],
[
20,
3
],
[
20,
5
],
[
20,
2
],
[
20,
14
]
],
backgroundColor: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"]
}]
},
options: {
scales: {
yAxes: [{
ticks: {
reverse: false
}
}]
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.js"></script>
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
</body>
You put the maximum value of your axis as the first or last (chart.js will render it the same) in your array. Then for the other value you enter the start point. So that would be max value - the percentage
I am using react-chart-js2#3.3.0 with chart.js#3.6.2
When my dataset contains all 0s, the y-axis scales from -1 to 1 as such:
See Image
How do I make it start at 0 regardless? There seems to be a workaround for this: here and here but these solutions did not work for me. Basically, the workaround is to include a max in the ticks but it appears to just ignore it. I also tried upgrading to react-chart-js2#4 but for some reason it breaks so I reverted it back to 3.3.0.
Here is my options object:
const options = {
responsive: true,
maintainAspectRatio: false,
plugins: {
legend: {
display: false,
},
},
layout: {
padding: 0,
},
scales: {
xAxes: [
{
gridLines: {
display: false,
drawBorder: false,
},
ticks: {
padding: 18,
fontColor: theme.palette.text.secondary,
},
},
],
yAxes: [
{
gridLines: {
borderDash: [6],
borderDashOffset: [0],
display: false,
color: theme.palette.divider,
drawBorder: false,
zeroLineBorderDash: [6],
zeroLineBorderDashOffset: [0],
zeroLineColor: theme.palette.divider,
},
ticks: {
padding: 12,
fontColor: theme.palette.text.secondary,
beginAtZero: true,
min: 0,
max: 100,
},
},
],
},
tooltips: {
enabled: true,
mode: "nearest",
intersect: false,
caretSize: 6,
displayColors: false,
yPadding: 8,
xPadding: 16,
borderWidth: 4,
borderColor: theme.palette.common.black,
backgroundColor: theme.palette.common.black,
titleFontColor: theme.palette.common.white,
bodyFontColor: theme.palette.common.white,
footerFontColor: theme.palette.common.white,
callbacks: {
title: () => {},
label: (tooltipItem) => {
return `New Users: ${tooltipItem.yLabel}`;
},
},
},
};
the min and max have to be outside of the ticks:
y: { ticks: { }, min: 0, max: 100 }
I'm looking to create a drilldown using the CChartBar available in the CoreUI documentation here: https://coreui.io/react/docs/3.3/components/CCharts/
I need to be able to get the month from the bar that is clicked, and when the bar is clicked, it needs to take the user to another page. How do I get the information? How to I make each bar clickable to send the user to the table page?
Currently here is the html
<div className="chart-container">
<CChartBar
datasets={[
{
label: "Expected Expirations",
type: "bar",
data: expectedExpirations,
backgroundColor: "#949fe8",
borderColor: "blue",
fill: true,
order: 2,
},
{
label: 'Actual Expirations',
type: "bar",
data: actualExpirations,
backgroundColor: '#556ad1',
borderColor: "blue",
fill: true,
order: 1,
},
{
label: 'Target Expirations',
backgroundColor: '#352c2c',
data: targetExpirations,
type: "line",
borderColor: "black",
fill: true,
order: 0,
borderWidth: 2,
fill: "#352c2c",
pointBackgroundColor: "#352c2c",
lineTension: 0,
}
]}
labels={dateLabels}
onClick={(event) => drillDown(event)}
options={{
maintainAspectRatio: false,
responsive: true,
tooltips: {
enabled: true,
},
scales: {
xAxes: [{
stacked: true,
scaleLabel: {
display: true,
labelString: "Month"
}
}],
yAxes: [{
ticks: {
stacked: true,
beginAtZero: true,
stepValue: 10,
max: maxOfAllExpirations
},
scaleLabel: {
display: true,
labelString: "Number of Lease Expirations"
}
}]
},
}}
/>
I would like to be able to click on the bar, and get the data that is being charted, so I can pass the month to another page.
You can use the onClick function for this:
var options = {
type: 'bar',
data: {
labels: ["December 2020", "Januarie 2021", "Feb 2021", "March 2021", "April 2021", "May 2021"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 3, 3],
backgroundColor: 'pink'
}]
},
options: {
onClick: (evt, activeEls) => {
console.log(activeEls[0]._model.label)
console.log(activeEls[0]._model.label.split(" ")[0])
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.js"></script>
</body>
<div className = "chart-container" >
<CChartBar
datasets = {
[{
label: "Expected Expirations",
type: "bar",
data: expectedExpirations,
backgroundColor: "#949fe8",
borderColor: "blue",
fill: true,
order: 2,
},
{
label: 'Actual Expirations',
type: "bar",
data: actualExpirations,
backgroundColor: '#556ad1',
borderColor: "blue",
fill: true,
order: 1,
},
{
label: 'Target Expirations',
backgroundColor: '#352c2c',
data: targetExpirations,
type: "line",
borderColor: "black",
fill: true,
order: 0,
borderWidth: 2,
fill: "#352c2c",
pointBackgroundColor: "#352c2c",
lineTension: 0,
}
]
}
labels = {
dateLabels
}
onClick = {
(event) => drillDown(event)
}
options = {
{
onClick: (evt, activeEls) => {
console.log(activeEls[0]._model.label)
console.log(activeEls[0]._model.label.split(" ")[0])
},
maintainAspectRatio: false,

Hell, all,
I would like to draw the chart like this:
Currently, I can use afterBuildTicks to get only zero yAxis. But the problem is that the whole other ticks were removed also. So Not sure if we have a way to draw zero tick and keep other ticks hidden except the label.
var ctx = document.getElementById("myChart").getContext("2d");
var myChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Value 1', 'Value 2', 'Value 3', 'Value 4'],
datasets: [{
label: "Dataset",
data: [20, 15, 27, 18],
backgroundColor: 'rgba(54, 162, 235,0.5)',
}],
},
options: {
responsive: true,
elements: {
line: {
fill: false
}
},
scales: {
xAxes: [
{
position: 'top',
display: true,
gridLines: {
display: true,
},
stacked: true,
ticks: {
fontColor: "#C4C4C4",
fontSize: 10,
}
}
],
yAxes: [
{
type: 'linear',
display: true,
position: 'right',
id: 'y-axis-1',
gridLines: {
display: true,
},
labels: {
show: true
},
stacked: false,
ticks: {
fontColor: "#C4C4C4",
fontSize: 10,
precision: 0,
suggestedMax: 100,
suggestedMin: -100
},
afterBuildTicks:function (axis) {
axis.ticks = [0]
}
}
]
},
tooltips: {
mode: 'label',
bodySpacing: 10,
titleMarginBottom: 10,
titleFontSize: 14,
titleFontStyle: 'bold',
footerAlign: 'right',
callbacks: {
label: (tooltipItem, data) => {
const label = data.datasets[tooltipItem.datasetIndex].label || ''
const value = tooltipItem.value
return ` ${label}: ${value}`
}
}
}
}
});

Thanks so much
I found the solution that use: gridLines options to draw chart with width is zero:
gridLines: {
display: true,
tickMarkLength: 10,
lineWidth: 0
}
Image
This is my current result bar
But I need the content to be collapsed when clicked, the content is similar to the picture below
Give a link to some library or some solution
in advance thankful
