How to add percentage in polar chartjs vuejs

i want to show the percentage at the chart, i tried to use tooltips but it's not working.
i'm using vue 2
polar chart
the code:
Codesandbox
polarChart: { options: { responsive: true, maintainAspectRatio: false, responsiveAnimationDuration: 500, yaxis: { show: true,
},
legend: { position: 'right', labels: { padding: 25, boxWidth: 10, showActualPercentages: true, fontSize: 15,
},
}, tooltips: { callbacks: { shadowOffsetX: 1, shadowOffsetY: 1, shadowBlur: 8,
},
}, scale: { scaleShowLine: true, scaleLineWidth: 1, ticks: { display: false,
}, reverse: false, gridLines: { display: false,
},
}, animation: { animateRotate: false,
},
},
chartData: { labels: ['Africa', 'Asia', 'Europe'],
The data -----
datasets: [
{ label: 'Population (millions)', ba
ckgroundColor: [
'#836AF9',
'#ffe800',
'#28dac6',
'#ffe802',
'#FDAC34',
'#299AFF',
'#4F5D70',
'#2c9aff',
'#84D0FF',
'#EDF1F4',
], data: [3141, 3132, 2112],
borderWidth: 0,
},
],
},
i tried to use tooltips but it does not working.
i want that the chart show the percentage and the value.

Chart JS tooltip labels spaced as spaceBetween

I have a stacked bar chart where the tooltip shows Label: $value & I would like this to be set as space-between so Label is aligned to the left & $value is aligned to the right, allowing all the numerical values to align. For example:
Label 1: $10,000
Label 2: $50,000
Label 3: $100,000
Here is the calculator. Just press the compound button to show the chart.

Chart.js multiple datas between labels

i am using chart.js to display data. I would like to display several points per label.
A picture is better than sentences, here is an example of a poker platform :
We see that between the labels several points are recorded.
Here is my code with chart.js currently with test data :
var config = {
type: 'line',
data: {
labels: ['2', '4', '6', '8', '10','12','14','16'],
datasets: [{
label: 'Bankroll',
backgroundColor: window.chartColors.grey,
borderColor: window.chartColors.grey,
data: [20,60,80,90,120,150,170,210,260,220,150,10,220,150,220,150],
fill: false,
}]
},
options: {
responsive: true,
title: {
display: true,
text: 'Statistiques de votre bankroll'
},
tooltips: {
mode: 'index',
intersect: false,
},
hover: {
mode: 'nearest',
intersect: true
},
animation: {
duration: 2000
},
scales: {
xAxes: [{
display: true,
scaleLabel: {
display: true,
labelString: 'Nombre de tournois'
}
}],
yAxes: [{
display: true,
scaleLabel: {
display: true,
labelString: 'Total Cumulé (Euros)'
}
}]
}
}
};
le rendu est le suivant :
We observe that I have not 8 data but 16 and only 8 are displayed. I would like to keep the same number of labels by displaying all the points, is this possible?
Thank you so much ! :)

You could deduct the data.labels from the data using Array.map().
labels: data.map((v, i) => i + 1)
Then you would have to define the desired ticks.stepSize for the x-axis.
xAxes: [{
ticks: {
stepSize: 2
},
optionally you may also define ticks.maxTicksLimit instead.
Please take a look at your amended code and see how it works.
var data = [20, 60, 80, 90, 120, 150, 170, 210, 260, 220, 150, 10, 220, 150, 220, 150];
var config = {
type: 'line',
data: {
labels: data.map((v, i) => i + 1),
datasets: [{
label: 'Bankroll',
backgroundColor: 'grey',
borderColor: 'grey',

labelString: 'Nombre de tournois'
}
}],
yAxes: [{
scaleLabel: {
display: true,
labelString: 'Total Cumulé (Euros)'
}
}]
}
}
};
new Chart('canvas', config);

Chartjs with multiple y axes and different scales

How can I use different scales in Y Axes with ChartJs?
I have this datasets:
[ 1450478,2645844,1840524,640057,1145844,1530500,1695844,1778654,1450478,1645844,1450478,1645844 ]
[ 3.14, 4.15, 3.09, 3.48, 4.05, 3.99, 4.39, 4.15, 4.10, 3.98, 3.54, 3.50 ]
https://jsfiddle.net/psycocandy/ad18Lc4u/18/
The smallest scale represented by the line is obviously very close to the scale of 0. How do I make this same line visible without having to filter by legend?

I found the problem, updated fiddle: https://jsfiddle.net/psycocandy/fwncq25a/14/
To set the correspondent ID in the dataset with the yAxes, the correct way is to use yAxisID:
var chartData = [
[1450478, 2645844, 1840524, 640057, 1145844, 1530500, 1695844, 1778654, 1450478, 1645844, 1450478, 1645844],
[3.14, 4.15, 3.09, 3.48, 4.05, 3.99, 4.39, 4.15, 4.10, 3.98, 3.54, 3.50]
];
var dataSet = {
labels: ['Janeiro', 'Fevereiro', 'Março', 'Abril', 'Maio', 'Junho',
'Julho', 'Agosto', 'Setembro', 'Outubro', 'Novembro', 'Dezembro'
],
datasets: [{
type: 'line',
label: 'Preço Médio Mensal',
yAxisID: 'y-axis-0',
borderColor: '#17522f',
fill: false,
backgroundColor: '#17522f',

formatter: function (value, context) {
return numeral(value).format('0,0.00');
},

}
}
},{
type: 'bar',
label: 'Total Mensal',
yAxisID: 'y-axis-1',

},

};
var chart = new Chart(document.getElementById('myChart'), {

if(tooltipItem.datasetIndex > 0){
formatedValue = numeral(value).format('$ 0,0.00');
}else{
formatedValue = numeral(value).format('$ 0,0.00');
}
return ' ' + formatedValue;
},
}
},
responsive: true,
scales: {
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true,
position: 'left',
type: 'linear',
scaleLabel: {
display: true,
},
id: 'y-axis-1',
ticks: {
beginAtZero:true,
callback: function (tick, index, ticks) {
return numeral(tick).format('(0,0)');
},
}
}, {
stacked: false,
position: 'right',
type: 'linear',
id: 'y-axis-0',
ticks: {
max: 10,
stepSize: 1,
display: true,
beginAtZero: true,
fontSize: 13,
padding: 10,
callback: function (tick, index, ticks) {
return numeral(tick).format('$ 0,0');
}
}
}]
}
}
});

In Chart.js 3, the syntax is slightly different. The axes are identified by their scaleId:
Namespace: options.scales[scaleId]
datasets: [
{
type: 'line',
yAxisID: 'y1',
},
{
type: 'line',
yAxisID: 'y2',
}
]
scales: {
x: {
stacked: false,
y1: {
position: 'left',
stacked: false,
},
y2: {
position: 'right',
stacked: false,
},
}
See the Charts.js axes documentation for more.

chart js in an especific label

I need to put a line in my chart to indicate where the day changes to the next. The initial label of the day is 00:00. Is there a function to put a line like this in my chart, that will always appear in the labels at 00:00?
The config of the chart below:
Chart.defaults.global.defaultFontColor = 'white';
graffic = new Chart(document.getElementById("graffic").getContext('2d'), {
type: 'line',
fill: false,
data: {
labels : date_label,
fill: false,
datasets:data_to_grafic
},
options: {
title: {
position:'top',
display: true,
text: device
},
scales: {
xAxes: [{
display: true,
scaleLabel: {
display: true,
labelString: 'HRS'
}
}],
yAxes: [{
ticks: {beginAtZero:true},
display: true,
scaleLabel: {
display: true,
labelString: 'BPS'
}
}]
}
}
});
graffic.update();

Solution using chartjs-plugin-annotation (https://github.com/chartjs/chartjs-plugin-annotation)
var date_label = ['8:00', '9:00', '10:00', '11:00', '00:00', '01:00', '02:00', '03:00', '4:00'];
var data_to_grafic = [{
label: "My First dataset",
backgroundColor: '#ddd',
borderColor: '#f00',
fill: false,
data: [0, 0, 15000, 35000, 10000, 36000, 0, 0, 0, 0]
}];
var graffic = new Chart(document.getElementById("graffic").getContext('2d'),{
type: 'line',
data: {
labels: date_label,
fill: false,
datasets: data_to_grafic
},
options: {
title: {
position: 'top',
display: true,
text: 'My Title'
},
annotation: {
annotations: [{
type: "line",
mode: "vertical",
scaleID: "x-axis-0",
value: "00:00",
borderColor: "red",
borderWidth: 2
}]
},
scales: {
xAxes: [{
display: true,
scaleLabel: {
display: true,
labelString: 'HRS'
}
}],
yAxes: [{
ticks: {
beginAtZero: true
},
display: true,
scaleLabel: {
display: true,
labelString: 'BPS'
}
}]
}
}
