ECharts how to set different symbol for different marklines in one chart

In echarts, I have a bar chart, I want to add two markLine for it, but for the 'average' line I need the arrow style, for the 'test' line I do not want any symbol at the start and end of the line.
When I use below setting,it will set all markLines without arrow while I want to control each markLine's style separately.
markLine: {
symbol:"none",
data:[]
}
function format(data)
{
data = parseFloat(data);
return data.toLocaleString('en-US', {style: 'currency', currency: 'USD'});
}
var columns_basic_element = document.getElementById("columns_basic");
// Basic columns chart
if (columns_basic_element) {
// Initialize chart
var columns_basic = echarts.init(columns_basic_element);
var data_parts = [12164.58, 13251.94, 21927.18, 13945.88, 13339.14, 21756.32, 19340.50, 22307.53];
var data_labor = [82757.65,97032.46,112864.88,83359.07,85858.48,186564.83,118206.58,132575.22];

You have mistake with incorrect symbol declaration, do like this:
markLine: {
symbol: 'icon' // <---- it's wrong
data: [{
symbol: 'diamond', // <---- it's right
symbolSize: 30,
name: 'average line',
type: 'average'
},{
symbol: 'circle',
symbolSize: 30,
name: 'max line',
type: 'max'
}]
}
var myChart = echarts.init(document.getElementById('main'));
// Unsert your code below
var option = {
xAxis: {
data: ["1", "2", "3", "4", "5", "6"]
},
yAxis: {},
series: [{
name: 'Series1',
stack: '1',
type: 'bar',
data: [5, 20, 36, 10, 10, 20],
markLine: {

Proper format of json for Highchart.js with multiple series

I have examples json data for Higcharts USD currency:
https://cdn.jsdelivr.net/gh/highcharts/highcharts#v7.0.0/samples/data/usdeur.json
So i added simply one value to data, there not show in a chart.
[
[
1167609600000,
50,
30
],
[
1167609600001,
60,
40
],
[
1167609600002,
70,
50
]
]
My code:
function myFunction() { Highcharts.getJSON(
'http://192.168.0.157/log1.json', function (data) {
Highcharts.chart('container', {
chart: {
zoomType: 'x', backgroundColor:"#e7ecea"
},
title: {
text: 'Pomiary'
},
subtitle: {
text: document.ontouchstart === undefined ?
'select' : 'Pinch the chart to zoom in'
},
xAxis: {
type: 'datetime'
},
yAxis: {
title: {
text: 'Exchange rate'
}
},
legend: {
enabled: false
},
plotOptions: {
area: {
fillColor: {
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
marker: {
radius: 2
},
lineWidth: 1,
states: {
hover: {
lineWidth: 1
}
},
threshold: null
}
},
series: [{
type: 'area',
name: 'speed',
data: data
}, {
type: 'area',
name: 'speed2',
data: data
}]
}); } );
};
How i can add next series?

The simplest way is to use keys property:
series: [{
data: data
}, {
keys: ['x', 'someValue', 'y'],
data: data
}]

Highcharts chart didn't redraw after vue data changed

I grab the example from: https://www.highcharts.com/demo/column-stacked
Also referring some of the code from: How to use Vue bound data in Highcharts?
I build a sample as bellow:
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/highcharts/7.1.1/highcharts.js"></script>
</head>
<body>
<div id="app">
<div id="container">
</div>
</div>
</body>
</html>
<script>
new Vue({
el: "#app",
data: {
chart: undefined,
config: {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: ( // theme
Highcharts.defaultOptions.title.style &&
Highcharts.defaultOptions.title.style.color
) || 'gray'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
name: 'John',
data: [3, 3, 4, 8, 2]
}, {
name: 'Jane',
data: [3, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 3, 5]
}]
},
},
mounted() {
this.render();
// simulation of some data changing after some time
setTimeout(() => {
this.config.series = [{
name: 'John',
data: [53, 23, 24, 27, 32]
}, {
name: 'Jane',
data: [23, 22, 23, 32, 31]
}, {
name: 'Joe',
data: [33, 24, 24, 32, 35]
}]
console.log('updated')
}, 3000)
},
watch: {
config() {
this.render();
},
},
methods: {
render() {
this.chart = Highcharts.chart('container', this.config)
}
}
})
</script>
But I don't know why the chart wouldn't redraw after config.series updated ( with higher value of each category).

The problem is your config watcher only watch the change of config not its nested properties so this.config.series = [...] won't trigger your watcher.
First solution, use deep option:
watch: {
config: {
handler() {
this.render()
},
deep: true
}
}
Demo
Second solution, use spread syntax to assign the whole object:
this.config = {
...this.config,
series: [{ /* */ }]
}
Demo

Here is the solution for you:
Destruct the config object in render method to lose a reference:
render() {
this.chart = Highcharts.chart('container', {...this.config});
}
Change your config watcher to deep (that way watcher will react when you are changing property that belongs to the object e.g. this.config.series = [...]):
config: {
deep: true,
handler() {
this.render();
}
}

Echarts how do you add dashed vertical line in between specific bars on bar chart?

I am working with Echarts and created a bar chart. I am trying to add two vertical dashed lines to separate Source3 and Source4 and another dashed vertical line to show separation of SourceSix and SourceSeven. I have tried messing around with markLine to a bar and adding a line as part of the data after a bar but I can seem to figure this out.
The code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>ECharts</title>
<!-- including ECharts file -->
<script src="echarts.js"></script>
</head>
<body>
<!-- prepare a DOM container with width and height -->
<div id="main" style="width: 1600px;height:800px;"></div>
<script type="text/javascript">
// based on prepared DOM, initialize echarts instance
var myChart = echarts.init(document.getElementById('main'));
// specify chart configuration item and data
var option = {
title: {
text: 'Counts by Intel Source'
},
legend: {
data:['Count']
},
xAxis: {
type: 'category',
data: ['SourceOne','SourceTwo','SourceThree','SourceFour','SourceFive','SourceSix','SourceSeven','SourceEight'],
axisLabel: {
fontWeight: 'bold',
fontSize: 16,
margin: 1,
}
},
yAxis: {
type: 'log',
axisLabel: {
fontWeight: 'bold',
}
},
labelLine: {
lineStyle: {
color: 'rgba(255, 255, 255, 0.3)'
}
},
series: [
{
name: 'SourceOne',
type: 'bar',
stack: 'Chart 1',
color: '#ed2d2e',
data: [1819931,,,,,,,],
},
{
name: 'SourceTwo',
type: 'bar',
stack: 'Chart 1',
color: '#0bb5b5',
data: [,1291396,,,,,,]
},
{
name: 'SourceThree',
type: 'bar',
stack: 'Chart 1',
color: '#662c91',
data: [,,161,,,,,]
},
{
name: 'SourceFour',
type: 'bar',
stack: 'Chart 1',
color: '#0e107b',
data: [,,,133279,,,,]
},
{
name: 'SourceFive',
type: 'bar',
stack: 'Chart 1',
color: '#a11d20',
data: [,,,,1275,,,]
},
{
name: 'SourceSix',
type: 'bar',
stack: 'Chart 1',
color: '#f37d22',
data: [,,,,,119,,]
},
{
name: 'SourceSeven',
type: 'bar',
stack: 'Chart 1',
color: '#008c47',
data: [,,,,,,25224,]
},
{
name: 'SourceEight',
type: 'bar',
stack: 'Chart 1',
color: '#1859a9',
data: [,,,,,,,6798]
},
]
};
// use configuration item and data specified to show chart
myChart.setOption(option);
</script>
Desired output:

I've managed to achieve a similar effect to what you're looking for using the following option: I've converted your x-axis to be a 'value' x-axis, so that we can put markerLines at specific places in between your series. In doing so, you need to assign an x-axis index to each of your data points, but it also allows you to add an additional point to sourceThree and sourceSix which would let you draw a line in between the two as a type:'average' markLine:
option = {
title : {
text: 'Chart Title',
subtext: 'subtitle'
},
tooltip : {
trigger: 'axis',
axisPointer:{
show: true,
type : 'cross',
lineStyle: {
type : 'dashed',
width : 1
}
},
formatter : function (params) {
return params.seriesName + ' : [ '
+ params.value[0] + ', '
+ params.value[1] + ' ]';
}
},
xAxis : [
{
type : 'value'
}
],
yAxis : [
{
type : 'log',
axisLine: {
lineStyle: {
color: '#dc143c'
}
}
}
],
series : [
{
name:' SourceOne',
type:'bar',
data:[
[1, 1819931]
]
},
{
name:' SourceTwo',
type:'bar',
data:[
[2, 1291396]
]
},
{
name:' SourceThree',
type:'bar',
data:[
[3, 161], [4, 0]
],
markLine : {
silent: true, // ignore mouse events
data : [
// Horizontal Axis (requires valueIndex = 0)
{type : 'average', name: 'Marker Line', valueIndex: 0, itemStyle:{normal:{color:'#1e90ff'}}},
]
}
},
{
name:' SourceFour',
type:'bar',
data:[
[4, 133279]
]
},
{
name:' SourceFive',
type:'bar',
data:[
[5, 1275]
]
},
{
name:' SourceSix',
type:'bar',
data:[
[6, 119], [7, 0] // this extra data point is the hack to get your marker line in between your series
],
markLine : {
silent: true, // ignore mouse events
label: {show: false},
data : [
// Horizontal Axis (requires valueIndex = 0)
{type: 'average', name: 'Line Marker', valueIndex: 0},
]
}
},
{
name:' SourceSeven',
type:'bar',
data:[
[7, 25224]
]
},
{
name:' SourceEight',
type:'bar',
data:[
[8, 6798]
]
}
]
};
This should result in the following chart, and you can try it yourself by pasting that option here:

Change xAxis and yAxis title of drilldown chart after entering into second series

I drew a drilldown chart and I don't know how to change both x-Axis and y-Axis title after clicking the bars and go to second chart. Also how to change to default title after clicking drillUp button and go back to first chart.
For example, I want my first chart's x-Axis title to be "Percentage Arange" and y-Axis title to be "Number of Schools". And second chart's x-Axis title to be "School Name" and yAxis title to be "Percentage".
I searched for some related code. There is one about how to change the title of the drilldown chart:
var defaultTitle = "Basic drilldown";
var drilldownTitle = "More about ";
var chart = new Highcharts.Chart({
chart: {
type: 'column',
renderTo: 'container',
events: {
drilldown: function(e) {
chart.setTitle({ text: drilldownTitle + e.point.name });
},
drillup: function(e) {
chart.setTitle({ text: defaultTitle });
}
}
},
title: {
text: defaultTitle
},
// ... more options});
However, i don't know how to use for my case.
Here is the code:
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Basic drilldown'
},
xAxis: {
type: 'category',
title: {
enabled: true,

}
},

}
},

},
plotOptions: {
