Data Labels wrongly positioned on bar chart - chartjs

I'm using chartjs-plugin-datalabels to show values on chart, but the labels are not centered.
The main part is in the datasets.datalabels where I can override default settings, which sets to center anyway, but wanted to show where its done.
I have tried positione it to the right, but as the value getting bigger, the datalabel is less centered.
Chart.register(ChartDataLabels);
const data_tafkidim_cat_count = {
labels: window.TafkidimCatCount.map((el) => el.TafkidCat.split(' ')).slice(0, pagination['tafkidim_cat_count'].show),
datasets: [
{
data: window.TafkidimCatCount.map((el) => el.Total),
backgroundColor: Setcolors(),
borderColor: Setcolors(1),
borderWidth: 1,
datalabels: {
anchor: 'center',
align: 'center',
},
},
],
};
const config_tafkidim_cat_count = {
type: 'bar',
data: data_tafkidim_cat_count,
options: {
scales: {
x: {
grid: {
borderColor: '#829AB1',
},
ticks: {
color: '#627D98',
},
reverse: true,
},
y: {
grid: {
borderColor: '#829AB1',
},
beginAtZero: true,
ticks: {
color: '#627D98',
},
},
},
plugins: {
title: {
text: TL['tafkidim_cat_count'],
padding: {
bottom: 20,
},
},
legend: {
display: false,
},
tooltip: {
callbacks: {
title: (context) => {
return context[0].label.replaceAll(',', ' ');
},
},
},
},
},
};
const tafkidim_cat_count = new Chart('#tafkidim-cat-count'.Element().getContext('2d'), config_tafkidim_cat_count);

solved it with
textAlign = "center"
apparently the default is "start".

Vue apexcharts Y-axis label hiding in horizontal barchart

I'm using apexcharts with vue (vue-apexcharts 1.6.1) and making horizontal barchart for UHD resolution. The apexcharts inner is overflowing the chart width which is 100%.
Here is the template code:
<template>
<div>
<apexchart height="820" type="bar" :options="options" :series="series"></apexchart>
</div>
</template>
And here is the chart options:
options() {
return {
chart: {
type: 'bar',
width: "100%",
height: 820,
toolbar: {
show: false
}
},
legend: {
show: false
},
xaxis: {
categories: this.categoryData,
axisBorder: {
show: false
},
axisTicks: {
show: false
},
labels: {
show: false
}
},
yaxis: {
opposite: true,
labels: {
style: {
colors: ["#BEBFCB"],
fontSize: "40px"
}
}
},
fill: {
colors: ["#0E5CAD", "#EA5455", "#0396FF", "#7367F0", "#D939CD"],
type: "gradient",
gradient: {
shade: "light",
gradientToColors: [
"#79f1a4",
"#feb692",
"#abdcff",
"#ce9ffc",
"#f6ceec"
],
shadeIntensity: 1,
type: "diagonal1",
opacityFrom: 1,
opacityTo: 1,
stops: [0, 100]
}
},
plotOptions: {
bar: {
horizontal: true,
distributed: true,
borderRadius: 10,
barHeight: "70%",
colors: {
ranges: [
{
from: 0,
to: 0,
color: "pink"
}
],
backgroundBarColors: "#272A52",
backgroundBarRadius: 10
}
}
},
dataLabels: {
enabled: false
},
tooltip: {
enabled: false
},
responsive: [
{
breakpoint: 3199,
options: {
chart: {
height: 300
},
yaxis: {
opposite: true,
labels: {
style: {
colors: ["#BEBFCB"],
fontsize: "14px"
}
}
},
plotOptions: {
bar: {
borderRadius: 4,
colors: {
backgroundBarRadius: 4
}
}
}
}
}
]
};
}
Here's the output of above code:

How can I adjust the chart so that my site matches the design? Right now the font-size of label is 40px in UHD resolution.
Thanks
P.S. I'm not using flex in any ancestor elements.

I solved this issue by giving maxWidth to y-axis label and by manipulating my x-axis categories to be in multiline.
After fix image
yaxis: {
opposite: true,
labels: {
maxWidth: "auto",
style: {
colors: ["#BEBFCB"],
fontSize: "40px"
}
}
}

Change color of single bar in apex chart

I've some trouble making changes in the bar of color in the apex chart. The chart is a mixed chart (Line/Bar).
I want to change a single bar color.
I've tried the solution is that is to added a fillColor into the series.data as per the apex chart documents but it does not work.
Chart Snap
enter image description here
Here is my code.
where
response.device.data.values AND response.flowmeter.values is a array of values.
if (newChart !== null) {
newChart.destroy();
}
var options = {
chart: {
height: 350,
stacked: false,
height: '400',
toolbar: {
tools: {
download: true,
selection: false,
zoom: false,
zoomin: false,
zoomout: false,
pan: false,
reset: false,
customIcons: []
}
}
},
dataLabels: {
enabled: false
},
stroke: {
width: [2, 1],
curve: 'stepline'
},
yaxis: [
{
axisTicks: {
show: true,
},
axisBorder: {
show: true,
color: '#008FFB'
},
labels: {
style: {
color: '#008FFB',
}
},
title: {
text: "<?=_('Device(s)')?> (m3)",
style: {
color: '#008FFB'
}
},
tooltip: {
enabled: true
}
},
{
opposite: true,
axisTicks: {
show: true,
},
axisBorder: {
show: true,
color: '#00E396'
},
labels: {
style: {
color: '#00E396',
}
},
title: {
text: "<?=_('Flowmeter(s)')?> (m3)",
style: {
color: '#00E396',
}
}
},
],
tooltip: {
followCursor: true,
},
legend: {
horizontalAlign: 'center',
offsetX: 40
},
zoom: {
enabled: false
},
xaxis: {
categories: response.device.data.labels,
labels: {
style: {
fontSize: '10px'
}
}
},
series: [
{
name: '<?=_('Device(s)')?>',
type: 'line',
data: response.device.data.values
},
{
name: '<?=_('Flowmeter(s)')?>',
type: 'bar',
data: response.flowmeter.values
}
],
};
newChart = new ApexCharts(document.querySelector("#new-chart"), options);
newChart.render();

You can set color prop in the object of the series.
Somethings like that:
series: [
{
name: '<?=_('Device(s)')?>',
type: 'line',
color: "00FA9A",
data: response.device.data.values
},
{
name: '<?=_('Flowmeter(s)')?>',
type: 'bar',
color: "#F44336",
data: response.flowmeter.values
}
],

You could probably make use of passing a function to the fill property. Check this link: https://apexcharts.com/docs/options/fill/. You can also customize based on the series index.

colors: [function({ value, seriesIndex, w }) {
return colors(value)
}],
function colors(id) {
var colors = [
"#33b2df",
"#546E7A",
"#d4526e",
"#13d8aa",
"#A5978B",
"#2b908f",
"#f9a3a4",
"#90ee7e",
"#f48024",
"#69d2e7"
];
return colors[id] ?? '#33b2df';
}

Apex Chart Line Graph not showing data label only on first month

For some reason, the data label isn't being displayed on my line graph by ApexChart.
Seems like the chart's JS is relatively simple:
var options = {
chart: {
height: 380,
type: 'line',
zoom: {
enabled: false
},
toolbar: {
show: false
},
dropShadow: {
enabled: true,
top: 10,
left: 0,
bottom: 0,
right: 0,
blur: 2,
color: '#45404a2e',
opacity: 0.35
},
},
colors: ['#1ecab8', '#56b9db', '#ffb66e', '#eb3131', '#373d3f'],
dataLabels: {
enabled: true,
},
stroke: {
width: [3, 3, 3, 3, 3],
curve: 'smooth'
},
series: [{
name: "Informational",
data: [5,10,15,20]
},
{
name: "Low",
data: [2,3,4,5]
},
{
name: "Medium",
data: [9,0,2,3]
},
{
name: "High",
data: [1,2,3,4]
},
{
name: "Critical",
data: [0,0,0,10]
}
],
title: {
text: 'Reported Findings',
align: 'left',
style: {
fontSize: "14px",
color: '#ffffff'
}
},
grid: {
row: {
colors: ['transparent', 'transparent'], // takes an array which will be repeated on columns
opacity: 0.2
},
borderColor: '#f1f3fa'
},
markers: {
style: 'inverted',
size: 6
},
xaxis: {
categories: <%= raw #series_months %>,
axisBorder: {
show: true,
color: '#bec7e0',
},
axisTicks: {
show: true,
color: '#bec7e0',
},
},
yaxis: {
min: 0,
max: 50
},
legend: {
position: 'top',
horizontalAlign: 'right',
floating: true,
offsetY: -25,
offsetX: 5
},
responsive: [{
breakpoint: 600,
options: {
chart: {
toolbar: {
show: false
}
},
legend: {
show: false
},
}
}]
}
var chart = new ApexCharts(
document.querySelector("#<%= #chart_id %>"),
options
);
chart.render();
What am I missing that is causing this to not display correctly? It doesn't make sense because if I change one of the first arrays from a 9 to a 10, then it shows up just fine:

Fixed this by updating the apexchart version from 3.15.6 to 3.19.3

echarts line between grouped bar chart

I am trying to make the data grouping more obvious in my chart:
I would like a line to go through the middle to indicate that they are two different data sets. However i am not quite sure how to do it.
Here is my code for generating the chart:
const frequencyChartoption = {
title: {},
tooltip: {},
legend: {
data: ['Frekvens', 'Vigtighed']
},
xAxis: {
type: 'category',
data: ['marker_01', 'marker_02'],
axisLine: {
show: true
},
axisTick: {
show: true
},
axisLabel: {
formatter: function (value) {
return '{' + value + '| }\n{value|}';
},
margin: 20,
rich: {
value: {
lineHeight: 30,
align: 'center'
},
marker_01: {
height: 20,
align: 'center',
backgroundColor: {
image: icons.marker_01
}
},
marker_02: {
height: 20,
align: 'center',
backgroundColor: {
image: icons.maker_02
}
},
}
}
},
yAxis: {
axisLine: {
show: true
},
axisTick: {
show: true
},
axisLabel: {}
},
series: [{
name: 'Frekvens',
type: 'bar',
data: frequencyChartFrequencyScore,
tooltip: {
formatter: '{c0}'
},
itemStyle: {
normal: {
color: colors[0],
label: {
interval: 5,
show: true,
position: 'top',
formatter: '\n{c}'
}
}
}
},
{
name: 'Vigtighed',
type: 'bar',
data: frequencyChartImportance,
tooltip: {
formatter: '{c0}'
},
itemStyle: {
normal: {
color: colors[1],
label: {
show: true,
position: 'top',
formatter: '\n{c}'
}
}
}
}
]
};
What can I try next?

I think what you are looking for is a splitLine.
Just enabled splitLine on your xAxis and style it accordingly.
xAxis: {
splitLine: {
show: true,
lineStyle: ...
}
}
