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);

I am building a covid-19 tracker, but when data is displayed on the graph using react charts title is coming out to be undefined
This is my chart code
<div >
{data?.length > 0 && (
<Line
data={{
datasets: [
{
backgroundColor: "rgba(204, 16, 52, 0.5)",
borderColor: "#CC1034",
data: data,
},
],
}}
options={options}
/>
)}
</div>
These are my option parameters
const options = {
legend: {
display: false,
},
elements: {
point: {
radius: 0,
},
},
maintainAspectRatio: false,
tooltips: {
mode: "index",
intersect: false,
callbacks: {
label: function (tooltipItem, data) {
return numeral(tooltipItem.value).format("+0,0");
},
},
},
scales: {
xAxes: [
{
type: "time",
time: {
format: "MM/DD/YY",
tooltipFormat: "ll",
},
},
],
yAxes: [
{
gridLines: {
display: false,
},
ticks: {
// Include a dollar sign in the ticks
callback: function (value, index, values) {
return numeral(value).format("0a");
},
},
},
],
},
};
Although legend is set to false I am getting an error.
Please tell me where I am going wrong, that will be helpful.
Image of a chart.
You need to pass the label property here
data={{
datasets: [
{
backgroundColor: "rgba(204, 16, 52, 0.5)",
borderColor: "#CC1034",
data: data,
label: "your label" // <-- pass this
},
],
}}
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
}
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 have a bar chart that takes data according to the year. I take the current name of the year from the main component as follows:
App:
<DonateChart year={this.state.active_menu}/>
DonateChart:
<Bar
data={{
labels: this.props.year === 2018 ? ['20.01', '20.02'] : [20.03],
datasets: [{
label: false,
fill: true,
backgroundColor: "#D9D9D9",
borderCapStyle: 'square',
pointBorderColor: "white",
data: this.props.year === 2018 ? ['2222', '3333'] : ['4444'],
spanGaps: false,
},
{
label: false,
fill: true,
backgroundColor: "#00ACE5",
borderCapStyle: 'square',
pointBorderColor: "white",
data: this.props.year === 2018 ? ['2222', '3333'] : ['4444'],
spanGaps: false,
}],
}}
options={{
responsive: false,
fullCornerRadius: false,
maintainAspectRatio: false,
tooltips: {enabled: false},
hover: {mode: null},
scales: {
yAxes: [{
stacked: true,
ticks: {
fontColor: 'black',
beginAtZero: true,
min: 0,
max: 5000,
stepSize: 1000,
fontFamily: 'HelveticaNeueCyr',
fontSize: 10,
},
gridLines: {
color: "rgba(0, 0, 0, 0.1)",
}
}],
xAxes: [{
stacked: true,
ticks: {
fontColor: '#black',
fontFamily: 'HelveticaNeueCyr',
fontSize: isMobile ? 8 : 10,
},
gridLines: {
color: "rgba(0, 0, 0, 0)",
},
}]
},
legend: {
display: false
},
title: {
display: false,
}
}}/>
But when I switch the year and the new key is in the this.state.year, the chart is not drawn.
After that, I tried to create two different charts, and switch between them depending on the state, like this:
const bar1 = <Bar some code />
const bar2 = <Bar some code />
return(
this.state.year === 2018 ? bar1 : bar2
)
It also did not lead to anything, the schedule is distorted.
Tell me, please, how to implement such functionality correctly.
I would be grateful for any advice
In charts there is a regular redrawing method.
If i pass into it true, like this: redraw={this.state.update}, everything works fine!
