How not to round values in apexchart - javascript

I need the graph to display the values without rounding, the same as shown in the tooltip

In your chart options dataLabels use the formatter to define the display value, e.g.
dataLabels: {
formatter: function(val) {
return val.toFixed(2);
}
}
Full example with demo chart taken from official docs and added custom label:
var options = {
series: [{
name: 'Marine Sprite',
data: [44, 55, 41, 37, 22, 43, 21]
}, {
name: 'Striking Calf',
data: [53, 32, 33, 52, 13, 43, 32]
}, {
name: 'Tank Picture',
data: [12, 17, 11, 9, 15, 11, 20]
}, {
name: 'Bucket Slope',
data: [9, 7, 5, 8, 6, 9, 4]
}, {
name: 'Reborn Kid',
data: [25, 12, 19, 32, 25, 24, 10]
}],
chart: {
type: 'bar',
height: 350,
stacked: true,
stackType: '100%'
},
plotOptions: {
bar: {
horizontal: true,
},
},
stroke: {
width: 1,
colors: ['#fff']
},
title: {
text: '100% Stacked Bar'
},
xaxis: {
categories: [2008, 2009, 2010, 2011, 2012, 2013, 2014],
},
dataLabels: {
formatter: function(val) {
return val.toFixed(2);
}
},
tooltip: {
y: {
formatter: function(val) {
return val + "K"
}
}
},
fill: {
opacity: 1
},
legend: {
position: 'top',
horizontalAlign: 'left',
offsetX: 40
}
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

Showing sums for stacked bar Apexcharts

I have been trying to sum the columns, but also show the the data between the columns.
I've been looking for documentation but haven't found it. I do not know if it is the correct place where I ask the question
Used the option dataLabels.
dataLabels: {
enabled: true,
formatter: function (val) {
return val + "%";
},
offsetY: -20,
style: {
fontSize: '12px',
colors: ["#304758"]
}
},
var options = {
series: [{
name: 'PRODUCT A',
data: [44, 55, 41, 67, 22, 43]
}, {
name: 'PRODUCT B',
data: [13, 23, 20, 8, 13, 27]
}],
chart: {
type: 'bar',
height: 350,
stacked: true,
toolbar: {
show: true
},
zoom: {
enabled: true
}
},
responsive: [{
breakpoint: 480,
options: {
legend: {
position: 'bottom',
offsetX: -10,
offsetY: 0
}
}
}],
plotOptions: {
bar: {
horizontal: false,
borderRadius: 10
},
},
xaxis: {
type: 'datetime',
categories: ['01/01/2011 GMT', '01/02/2011 GMT', '01/03/2011 GMT', '01/04/2011 GMT',
'01/05/2011 GMT', '01/06/2011 GMT'
],
},
legend: {
position: 'right',
offsetY: 40
},
fill: {
opacity: 1
}
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
<script src="https://cdn.jsdelivr.net/npm/apexcharts"></script>
<div id="chart"></div>
However, this just shows the sum of each column.

Highcharts legend item not displaying properly (until window is resized)

I have a chart with legend items which are overlapping each other (this is the image for itemDistance option set to 20 - clearly the distance between items is less than 20px, it seems that 20px is item distance between legend symbols):
The chart is fixed and legend is displayed properly only after resizing the window (image for exactly same configuration object - the only window has been resized):
I can't figure out what I have done wrong or if I have just encountered a bug in Highcharts. I'm using Highcharts v. 7.2.0 with HighchartsReactOfficial library v. 2.2.2. My configuration object:
const options: Highcharts.Options = {
chart: {
type: 'spline',
spacingLeft: 40,
spacingRight: 40,
},
title: {

display: 'none',
},
},
subtitle: {

display: 'none',
},
},
credits: {
enabled: false,
},
legend: {
itemDistance: 20,
itemStyle: {
color: '#7990A1',
},
},
plotOptions: {
series: {

},
},

data: [40, 3, 71, 20, 28, 31],
},
],
yAxis: {

Help will be greatly appreciated.

ReactJS ApexCharts not displaying tooltip

I take one of the examples posted and slightly modify it by removing some data. When the sets don't have the same number of data points, the tooltips stop displaying.
Please see the following two examples. The first one being the one posted in the docs. The second, the modified version. When hovering starting from the end data points, the tooltip doesn't display anything for the last columns.
Example from docs: https://codepen.io/junedchhipa/pen/YJQKOy

Your codepen example uses an older version of ApexCharts.
Please update by pulling the latest version here
https://cdn.jsdelivr.net/npm/apexcharts#latest
Also, if you have a different number of data-points in each series, you can turn off shared tooltip and only show the tooltip when the user hovers over bars/markers directly.
tooltip: {
shared: false,
intersect: true
}

Highcharts how to show certain tooltips and don't show others

I need to show tooltips for only the last two series when hovering the mouse over the graph. In this example the idea will be to show only the tool tips for the values 1699 and 1750. The rest of the values can't show any tooltips when hovering the mouse. How can I achive that? I haven't found any way to do so. Is it possible? Thanks in advance.

You can use the formatter like this :
tooltip: {
formatter: function() {
if(this.points[0].key < (this.points[0].series.xData.length -2)){
return false;
}
var s = [];
s.push(this.x);
this.points.forEach(function(point) {
s.push('<b>' + point.series.name + '</b>: ' + point.y);
});
return s;
},
split: true
},
Fiddle
Not the cleanest code (there still an error in the console) but it's work.
Edit
Following Deep 3015 comment, code and fiddle updated
You can wrap tooltip.prototype.renderSplit method to show the tooltip only if the points have certain x values.
Highcharts.wrap(Highcharts.Tooltip.prototype, 'renderSplit', function (p, labels, points) {
if (!this.options.showOnLastTwo) {
return p.call(this, labels, points)
}
const point = points[0]
if (point) {
const allowedXs = point.series.xData.slice(-2)
if (allowedXs.includes(point.x)) {
return p.call(this, labels, points)
}
}
this.destroy()
})
And set in tooltip options showOnLastTwo flag to true:
tooltip: {
split: true,
showOnLastTwo: true
},
The flag is not necessary but the wrap changes Highcharts globally so it will affect every chart - the flag will prevent this.

Highchart - Area chart: customize tooltip

I am trying to customize the tooltip of area chart. I am using Highchart for this.
I am plotting 3 series in area chart. My requirement is to show tooltip at fixed location in chart which is top center. Now, when i put cursor at any point then tooltip should show all series name and their current value where the cursor is. Refer below image:
Currently i am able to show tooltip on top - center and putting mouse at any point is showing current series name and data but it is showing current series name in all 3 places.
Highchart option:
Highcharts.chart('container', {

Please help. Thanks in advance!
It might be difficult to achieve the desired result without tooltip.formatter.
This is how you can build tooltip text in a formatter:
formatter: function(tooltip) {
const points = this.points;
let str = '<table><tr>';
points.forEach(point => {
str += '<td style="text-align:center">' + point.y + '</td>';
});
str += '</tr><tr>';
points.forEach(point => {
str += '<td><span style="font-size:20px;color:' + point.color + '">●</span> ' + point.series.name + '</td>';
});
str += '</tr></table>';
return str;
},
And position it in the center of the chart:
positioner: function () {
const chart = this.chart;
return { x: (chart.plotWidth + chart.marginRight - this.label.getBBox().width) / 2, y: chart.plotTop + 10 };
}
Example and output
https://jsfiddle.net/eb3ou25v/
You can achieve desired result using pointFormat method
This is how you can use this
pointFormat: '<table style="text-align:center; display: inline-block; background: white;"><tr><td>{point.y}</td></tr>' +
'<tr><td><span style="font-size:20px;color:{series.color}">●</span> {series.name}</td></tr></table>',
positioner: function () {
const chart = this.chart;
return { x: (chart.plotWidth + chart.marginRight - this.label.getBBox().width) / 2, y: chart.plotTop - 20 };
}
