How to add percentage after value data in chart

I need after each value to be a percent symbol ( % ) For example: 12% instead of 12
The below code in write in laravel php for the chartpie.
<script src="{{asset('assets/admin/js/vendor/apexcharts.min.js')}}"></script>
<script src="{{asset('assets/admin/js/vendor/chart.js.2.8.0.js')}}"></script>
<script>
var ctx = document.getElementById('tokenomi');
var myChart = new Chart(ctx, {
type: 'doughnut',
data: {
labels:<?=$label?>,
datasets: [{
data:<?=$values?>,
],
borderColor: [
'rgba(231, 80, 90, 0.75)'
],
borderWidth: 0,
}]
},
options: {
aspectRatio: 1,
responsive: true,
maintainAspectRatio: true,
elements: {
line: {
tension: 0 // disables bezier curves
}
},
scales: {
xAxes: [{
display: false
}],
yAxes: [{
display: false
}]
},
legend: {
display: false,
}
}
});
</script>
Check the current chart pie below, I tried a lot but I can't find a solution.
How do I add percent sign (%) behind of all values
Thanks

You need to define a tooltips.callback.label function as shown below. For further details please consult Chart.js v. 2.8.0 documentation here.
options: {
...
tooltips: {
callbacks: {
label: (tooltipItem, data) => data.datasets[0].data[tooltipItem.index] + '%'
}
},
...
Please note that you're using a rather old version of Chart.js, the today latest stable version is 3.7.0.

Chart.JS: How to make sharp lines to smooth curved lines

Hi I'm new at charts and this is my chartjs chart, it's working currently, but it's showing in sharp lines and I want to make it smooth curve lines on this chart. Any ideas?
function statistics(data) {
if ($('#stats-currency').length > 0) {
if (typeof(stats_currency) !== 'undefined') {
stats_currency.destroy();
}
if (typeof(data) == 'undefined') {
var currency = $('select[name="currency"]').val();
$.get(admin_url + 'home/stats_currency/' + currency, function(response) {
stats_currency = new Chart($('#stats-currency'), {
type: 'line',
data: response,
options: {
responsive:true,
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
}
}]
},
},
});
}, 'json');
} else {
stats_currency = new Chart($('#stats-currency'), {
type: 'line',
data: data,
options: {
responsive: true,
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
}
}]
},
},
});
}

This can be done through the option lineTension that needs to be defined on your dataset. Choose a value below 1.
datasets: [{
...
lineTension: 0.8
}]
By default, you should however already see curved smooth lines since accoring to Chart.js documentation, the default value is 0.4.
lineTension: Bezier curve tension of the line. Set to 0 to draw straight lines.
Please note that if the steppedLine value is set to anything other than false, lineTension will be ignored.

you can do it by adding tension value to your charts options
<canvas id="myChart"></canvas>
JS
const config = {
type: 'line', // your chart type
data: data, // pass here your data
options: {
elements: {
line: {
tension : 0.4 // smooth lines
},
},
},
};
// pass it like
const myChart = new Chart(
document.getElementById('myChart'),
config
);

Highcharts.js question: is it possible to keep some part of chart in visible area always, even if "overscoll" option is set

I need to show some empty space to far right of the chart. To do so I use "overscroll" option (https://api.highcharts.com/highstock/xAxis.overscroll). But if user zoom in chart and pans chart to far right there can be empty space without any part of candlestick chart displayed (https://screencast-o-matic.com/watch/cqnfFq3CII). Please advise is it possible to implement following chart behaviour and how to do so: to keep some part of chart in visible area always, even if "overscoll" option is set and user pans chart to the far right? Thanks!
Here is my code:
var ohlc = JSON.parse(ohlcStringified),
volume = JSON.parse(volumeStringified);
var interval = ohlc[ohlc.length - 1].x - ohlc[ohlc.length - 2].x;
var chart = Highcharts.stockChart('container', {
chart: {
borderWidth: 1,
panning: true,
},
title: {
text: 'Chart'
},
legend: {
enabled: true
},
rangeSelector: {
selected: 1,
enabled: false
},
scrollbar: {
enabled: false
},
xAxis: {
minPadding: 0.2,
overscroll: 50 * interval,
},
yAxis: [{
height: '40%'
}, {
top: '40%',
height: '30%',
offset: 0
}, {
top: '70%',
height: '30%',
offset: 0
}],
series: [{
type: 'candlestick',
id: 'candlestick',
name: 'AAPL',
data: ohlc,
tooltip: {
valueDecimals: 2
},
dataGrouping: {
enabled: false,
}
}, {
type: 'column',
id: 'volume',
name: 'Volume',
data: volume,
yAxis: 1,
dataGrouping: {
enabled: false,
}
}]
});
Here is live demo: http://jsfiddle.net/ogorobets/bfcs9gx7/2/

It's possible, however, it requires some custom logic. It can be achieved using xAxis.events.afterSetExtremes callback where you can check if the current axis minimum is greater than your limit (a value lower than maximum xData value). When it is true, set new axis extremes with your limit as a minimum value. Check the code and demo posted below.
Code:
xAxis: {
minPadding: 0.2,
overscroll: 50 * interval,
events: {
afterSetExtremes: function() {
var chart = this.chart,
xData = chart.series[0].xData,
maxValue = xData[xData.length - 5],
min = chart.xAxis[0].min,
max = chart.xAxis[0].max
if (min > maxValue) {
chart.xAxis[0].setExtremes(maxValue, max, true, false);
}
}
}
}

Infragistics igDataChart dynamic binding

I have a igdatagrid column chart in my application . The requirement is to update the chart as per the change in data. the chart also has Customtooltip on the bars which can be seen on hover . now when the data changes ,chart is rendered if tooltip is not used but when i use tooltip it shows error .
initially while loading my page everything works fine but after updating the datasource it shows some error
this is my javascript code
$("#chart").igDataChart({
width: "98%",
height: "350px",
dataSource: jsonObj,
title: "Sector Comparison",
windowResponse: "immediate",
axes: [{
name: "xAxis",
type: "categoryX",
label: "xValue",
labelTopMargin: 5,
gap: 5
}, {
name: "yAxis",
type: "numericY",
minimumValue: 0,
maximumValue: 109,
labelLocation: "outsideRight",
majorStrokeThickness: 2,
majorStroke: "#0856a7",
minorStroke: 'black',
minorInterval: 10,
interval: 50,
formatLabel: function (value) {
if (value == 50) {
return "Medium value";
}
},
}, {
name: "yAxis1",
type: "numericY",
title: "Rank",
minimumValue: 0,
maximumValue: 109,
labelLocation: "outsideLeft",
interval: 10,
formatLabel: function (value) {
return value;
},
}],
series: [{
name: "series1",
type: "column",
isHighlightingEnabled: true,
isTransitionInEnabled: true,
xAxis: "xAxis",
yAxis: "yAxis",
valueMemberPath: "value",
showTooltip: true,
remove: true,
isCustomCategoryStyleAllowed: true,
}],
assigningCategoryStyle: function (e, ui) {
var startIndex = ui.startIndex;
var endIndex = ui.endIndex;
var items =ui.getItems(startIndex,endIndex);
var color = ui.fill;
for (var i = 0; i < items.length; i++) {
if (items[i].color) {
color = items[i].color;
}
}
ui.fill = color;
}
this is the code i write while binding tooltip initially
//get
var series = $("#chart").igDataChart("option", "series");
series[0].tooltipTemplate;
//Set
$("#chart").igDataChart("option", "series",
[{
name: "series1",
type: "column",
isHighlightingEnabled: true,
isTransitionInEnabled: true,
xAxis: "xAxis",
yAxis: "yAxis",
valueMemberPath: "value",
showTooltip: true,
isCustomCategoryStyleAllowed: true,
tooltipTemplate: "CustomTooltipTemplate",
}]
);
"CustomTooltipTemplate" is my custom tooltip template that works completely fine initially
when i get the new data after which i try to update chart with tooltip
series[0].tooltipTemplate;
show error in console as
Cannot read property 'tooltipTemplate' of undefined
and if i don't use custom template and just use property showTooltip
Cannot read property 'updateToolTip' of undefined is shown ,
is there any way i can use custom tootltip and dataSource dynamically.
i used to update the datasource i,e jsonObj .
i found the solution .
on updation of chart i overwrite the series and assign datasource to the chart and renderseries as below and it works
$("#chart").igDataChart({
series: [{
name: "series1",
type: "column",
isHighlightingEnabled: true,
isTransitionInEnabled: true,
xAxis: "xAxis",
yAxis: "yAxis",
valueMemberPath: "value",
isCustomCategoryStyleAllowed: true,
}],
});
$("#chart").igDataChart("option", "dataSource", jsonObj);
$("#chart").igDataChart("renderSeries", "xAxis", false);
$("#chart").igDataChart("renderSeries", "yAxis", false);
$("#chart").igDataChart("renderSeries", "yAxis1", false);

Disable hover on HighCharts

I have building a pie chart using HighCharts library, and here is my chart:
// http://jsfiddle.net/t2MxW/20890/
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});
But the problem is that I don't want appearing tooltip on mouse over...
Is it possible to disable tooltip on hover?

Disabling tooltip just disables the tooltip but the hover effect is still present. To disable the hover effect, add the following to your plotOptions:
plotOptions: {
series: {
states: {
hover: {
enabled: false
}
}
}
},

You need to set the tooltip attribute to false, like so:
tooltip: { enabled: false },
jsFiddle here
Here's the full code for your case:
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
tooltip: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});

You might alternatively want to disable all mouse tracking in general, both tooltip and hover effects:
(copy and paste link) http://api.highcharts.com/highcharts#series.enableMouseTracking
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/plotoptions/series-enablemousetracking-false/
plotOptions: {
series: {
enableMouseTracking: false
}
}

The title of the question is about disabling hovering, so in case anyone else finds themselves here for that purpose, I'll elaborate on #SergeyB's answer.
There are a few options that affect how mouse hovering changes a series' styling. They each have different effects depending on the series type. I'll talk about line and pie series here, but generally, you can look under plotOptions.<seriesType>.states.hover for styling applied to the currently hovered series and plotOptions.<seriesType>.states.inactive for styling applied to the non-hovered series (e.g. plotOptions.pie.states.hover). None of these options affect the tooltip styling.
plotOptions.series.states.inactive
plotOptions.series.states.inactive affects the styling applied to all series that aren't currently being hovered over. To prevent them from fading into the background, set plotOptions.series.states.inactive.opacity to 1.
var chartOptions = {
// ...
plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
},
},
}
jsFiddle for line
jsFiddle for pie
plotOptions.series.states.hover
plotOptions.series.states.hover affects the styling applied to the series that's being hovered over. For example, for a line series, the default is to thicken the line width and apply a halo to the nearest point.
To disable any styling of a currently hovered line series, set plotOptions.series.states.hover.enabled to false.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
states: {
hover: {
enabled: false,
},
},
},
},
}
jsFiddle
Unfortunately, if we set this on a pie series, this will make the hovered slice fade into the background with the rest of the inactive slices (see this jsFiddle for an example). If we want to remove all hover styling without affecting the inactive styling, we can set plotOptions.series.states.hover.halo.size to 0 (which removes the halo) and plotOptions.pie.states.hover.brightness to 0 (which removes the brightening effect). Note that since brightness is specific to pie series, it's documented under plotOptions.pie instead of plotOptions.series (though it worked for me even when I added it under plotOptions.series).
var chartOptions = {
// ...
chart: {
type: "pie",
},
plotOptions: {
series: {
states: {
hover: {
halo: {
size: 0,
},
// this worked for me even though it's not
// documented under plotOptions.series:
//brightness: 0,
},
},
},
pie: {
states: {
hover: {
brightness: 0,
},
},
},
},
}
jsFiddle
plotOptions.series.stickyTracking
If you're using a line or area series, you may have noticed that as soon as you hover over the chart, even if you're not touching a series, the nearest series will receive hover styling and the rest will receive inactive styling. This is because plotOptions.series.stickyTracking is true by default for line and area series. If you set plotOptions.series.stickyTracking to false, hover and inactive styling will only be applied while you're hovering over a line.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
stickyTracking: false,
},
},
}
jsFiddle
plotOptions.series.enableMouseTracking
As #ninedozen noted, you can completely disable all responsive interactions based on mouse movement by setting plotOptions.series.enableMouseTracking to false. Note that this will also disable tooltips in addition to hover/inactive styling.
Options scope
To apply these options to all series in the entire chart, place them under plotOptions.series. To apply them only to certain series types (or if the option is specific to a certain series), place them under plotOptions.<seriesType>. To apply them to a specific series, place them inside that series' options.
var chartOptions = {
series: [
{
name: "series1",
type: "line",
data: [...],
// these options will only apply to series1, not series2 or series3
states: {...},
},
{
name: "series2",
type: "line"
data: [...],
},
{
name: "series3",
type: "pie"
data: [...],
}
],
plotOptions: {
// these options will apply to all series in the chart
series: {states: {...}},
// these options will only apply to series of type line
// i.e. series1 and series2
line: {states: {...}}
}
}

You can simply turn them of using the following:
tooltip: {
enabled: false
},

plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
}
}
I did this to display multiple line charts on hover.

In order to completely turn off tooltip and hover effects on a chart,
it is needed to turn off the tooltip, disable hover state and set inactive data opacity to 100%.
This answer is based on previous answers and shows a complete solution to the problem.
This is the configuration which turns off the hover and tooltip effects:
series: {
states: {
hover: {
enabled: false
},
inactive: {
opacity: 1,
}
}
},
tooltip: {
enabled: false
}

you can simply disable it by setting the option
tooltip:{
enabled: false
}

I usually just disable the style in css so I can still access the hover event in JS if needed...
.highcharts-tooltip {
display: none;
}

As specified in the accepted answer, you need to set
tooltip: { enabled: false }
Note - you must specify this as a property of your Highcharts.Options object (i.e. your chart options object, not a property of your series). So, either specify it in the JSON that you pass into your Highcharts.Chart object, or specify it as a property of a Highcharts.Options object that you explicitly create, before you pass it to you Highcharts.Chart
See https://api.highcharts.com/highcharts/tooltip.enabled
