Change color of single bar in apex chart - javascript

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

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';
}

i've have to hear for use the chart.UpdateSeries() but in my case I dnt know how to use it
Indeed, you have to use the updateSeries() method. It is documented here: Methods – ApexCharts.js
To help you, I give you an example with updateSeries() using a simple button. When you click on it, random integers are generated in the data array. The series is then updated accordingly.
let options = {
series: [{
name: 'Series',
data: [1, 7, 3]
}],
chart: {
type: 'line',
height: 350
},
dataLabels: {
enabled: false
},
xaxis: {
categories: ['Category 1', 'Category 2', 'Category 3']
}
};
let chart = new ApexCharts(document.querySelector('#chart'), options);
chart.render();
function getRandomNumber() {
return Math.floor(Math.random() * 10);
}
document.querySelector('button').addEventListener('click', () => {
chart.updateSeries([{
data: [getRandomNumber(), getRandomNumber(), getRandomNumber()]
}])
});
button {
padding: 10px;
color: white;
background-color: #0d6efd;
border: none;
border-radius: 5px;
cursor: pointer;
}
button:hover {
color: black;
background-color: #0dcaf0;
}

Selection zoom not working for Area chart in Apexchart for React Js

I have implemented an Area Chart using Apexchart for React Js. I have set options using useState. When I am updating the options by updating the state. When I am using selection zoom, the charts get zoomed and then gets reset within less than a second. Can someone help me with it? Thanks in advance.

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: ...
}
}
