ApexCharts: switch the tooltip title with the datalable

As the title says, i want to switch the tooltip header with the tootlip body text.
for me it makes no sense why the standard config is this way around...
i know i can create a custom tootlip but thats not my favorite way to do it.
the code im using currently
var options = {
series: [{
name: 'Series',
data: [v0, v1, v2, v3, v4]
}],
colors: ['#3979bd', '#c1a748', '#69b761', '#69b761', '#d54c4c'],
chart: {
type: 'bar',
height: 200
},
plotOptions: {
bar: {
distributed: true,
borderRadius: 0,
horizontal: true,
}
},
tooltip: {
enabled: true,
},
dataLabels: {
enabled: true,
},
xaxis: {
categories: ['open', 'planned', 'done', 'done cloud', 'stopped'],
}
};
var chart = new ApexCharts(document.querySelector("#overview_apex_sc4stats"), options);
chart.render();
and heres a image what i want

How to render Positive, Negative differences as area between two lines in eCharts?

If we have two line charts, comparing say My Portfolio vs Overall Portfolio, the area between two lines need to be highlighted as green where My Portfolio is more than Overall portfolio, and red where it is less.
This is the kind of output that is expected -
var chartDom = document.getElementById('profileAumChart');
var myChart = echarts.init(chartDom);
var option;
option = {
title: {
show: false
},
tooltip: {
trigger: 'axis'
},
legend: {
data: ['My Portfolio', 'Overall Portfolio']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
show: false
},
xAxis: {
type: 'category',
boundaryGap: false,
data: ['Jan-21','Feb-21','Mar-21','Apr-21','May-21', 'Jun-21', 'Jul-21', 'Aug-21', 'Sep-21', 'Oct-21', 'Nov-21', 'Dec-21']
},
yAxis: {
type: 'value'
},
series: [
{
name: 'My Portfolio',
type: 'line',
areaStyle: {
color: 'green',
//opacity: 1,
},
data: [150100,175965,185385,201384,206279,235905,238021,239323,245282,247671,255447,275911],
},
{
name: 'Overall Portfolio',
type: 'line',
areaStyle: {
color:'red',
//opacity:1
},
data: [155066,165142,190811,192906,231941,250216,270047,288033,291842,308232,320941,334013],
}
]
};
option && myChart.setOption(option);
<script src="https://cdn.jsdelivr.net/npm/echarts#5.3.0/dist/echarts.min.js"></script>
<div id="profileAumChart" style="width:100%; height:270px;"></div>

I was able to replicate the effect with an hack. I added a hidden series which has the lowest of the two series, and use the attribute "areastyle" and their sub-attribute color and opacity along with z-index and I am able to show such region.
I am still looking for an elegant solution and in case someone post it would really appreciate it.
I am sharing my code which can help someone who intend to have similar effects using e-charts.
Thanks.

I ended up doing something similar to what #Amit Pandey did, but with stacked area charts.
https://echarts.apache.org/examples/en/editor.html?c=area-stack
You find the minimum of the 2 points, and render that as the bottom line/area, then you stack another area chart on top of that bottom line (this values for this stacked chart is the difference between the minimum values and the 'actual' chart value). You can then change the colour of the stacked chart to whatever you want and you can visualize that difference.
This still doesn't solve the issue of line intersects - so if you really want it to look good, you still have to calculate the intersections and add those points in - I ended up using mathjs' intersect function to do this.

HighMaps Not displaying Country Data

I am using Highcharts Js to display the Highmaps map bubble data. but the problem is that the Chart not plotting the bubble on Kosovo Country . For Example
if I have a JSON Data as Follows .
[
{"Country":"kosovo","persons":"2","CountryCode":"XK"},
{"Country":"india","persons":"2","CountryCode":"IN"}
]
The Map is being displayed with only India Country Data. and shows nothing of Kosovo Country.
This is The Javascript i used :
var data_country = [{"Country":"kosovo","persons":"2","CountryCode":"XK"},
{"Country":"india","persons":"2","CountryCode":"IN"}
] ;
data_country = data_country.map(function(el){
return {name: el.Country, z: parseInt(el.persons), 'iso-a2': el.CountryCode}
})
Highcharts.mapChart('world-map', {
chart: {
plotBorderWidth: 1,
plotBorderColor: '#ffffff',
borderColor: "#ffffff",
plotBackgroundColor: '#FFFFff',
map: 'custom/world'
},
title: {
text: "" ,
enabled: false
},
credits: {
enabled: false
},
exporting:{
enabled: false
},
legend: {
enabled: false
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
series: [{
name: 'Countries',
color: '#E0E0E0',
states: {
inactive: {
opacity: 1
}
},
enableMouseTracking: false
}, {
type: 'mapbubble',
name: '',
joinBy: 'iso-a2',//'iso-a3', 'code3'],
data: data_country,
minSize: '4%',
color: '#577ba8',
marker: {
fillOpacity: 0.9
},
maxSize: '4%',
tooltip: {
pointFormat: '{point.properties.name}'
}
}]
});
Please Tell me If I am missing something or is this an Highmaps error.

I see you are using the unofficial country code, as it has no official ISO country code:
The unofficial 2 and 3-digit codes are used by the European Commission and others until Kosovo is assigned an ISO code.
I also see that using KV in Highmaps seems to work. I'm not sure why they are using this partical country code. For example, from you code (JSFiddle):
var data_country = [{"Country":"kosovo","persons":"2","CountryCode":"KV"},
{"Country":"india","persons":"2","CountryCode":"IN"}
];
data_country = data_country.map(function(el){
return {name: el.Country, z: parseInt(el.persons), 'iso-a2': el.CountryCode}
});

Highmaps chart is empty in Angular 5

I have a component where I have to show high maps. No errors but the maps is always empty
My chart options object :
let chartData = [{ code3: "ABW", z: 105 }, { code3: "AFG", z: 35530 }];
this.chartConfigObject = new MapChart(<any>{
chart: {
borderWidth: 1,
map: 'custom/world'
},
title: {
text: 'World population 2013 by country'
},
subtitle: {
text: 'Demo of Highcharts map with bubbles'
},
legend: {
enabled: false
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
series: [{
name: 'Countries',
color: '#E0E0E0',
enableMouseTracking: false
}, {
type: 'mapbubble',
name: 'Population 2016',
joinBy: ['iso-a3', 'code3'],
data: chartData,
map: mapData,
minSize: 4,
maxSize: '12%',
tooltip: {
pointFormat: '{point.properties.hc-a2}: {point.z} thousands'
}
}]
});
When I console the created MapChart object i am getting the series as null always.
What am i missing and why the maps series is always null?
I am using angular-highcharts component as explained here :
https://github.com/cebor/angular-highcharts
reproduced in stackblitz: https://stackblitz.com/edit/angular-highcharts-stock-nbvnuw?file=app%2Fapp.module.ts

You are not providing the map data to your chart , so it doesn't know which map to show. Try showing the map data like mapData: Highcharts.maps['custom/world'] under Series.
If you cannot access the maps in your Highcharts reference , try importing all the maps (JS files) from the HighMaps library into your project and reference them in your typescript component file like this:
const Highcharts = {maps: {}};
require('../../../assets/maps')(Highcharts); //your custom project path
and use mapData: Highcharts['maps']['custom/world'] or whatever is the map you wanted to use like 'countries/us/us-all'
Below is working map code using angular-highcharts to plot the map and points on it:
getMap(data) {
return new MapChart({
chart: {
events: {
load: function (point) {
//do something here on page load
}
},
spacingBottom: 20
backgroundColor: '#FFF',
style: {fontFamily: 'inherit'}
},
title: {
text: ''
},
mapNavigation: {
enabled: true
},
tooltip: {
headerFormat: '',
formatter: function () {
var toolTipTxt = '<b>' + this.point.options.name + '</b>';
return toolTipTxt;
}
},
plotOptions: {
series: {
color: '#00A778',
marker: {
radius: 6,
symbol: 'circle',
lineColor: '#00A778',
lineWidth: 1,
states: {
select: {
fillColor: '#00A778',
lineWidth: 1,
lineColor: '#00A778'
}
}
},
point: {
events: {
click: function () {
this.select(null, true);
}
}
}
}
},
series: [
{
//mapData: Highcharts['maps']['custom/world']
mapData: Highcharts.maps['custom/world'],
name: 'Basemap',
borderColor: '#A0A0A0',
nullColor: 'rgba(200, 200, 200, 0.3)',
showInLegend: false,
data: []
},
{
// Specify points using lat/lon
type: 'mappoint',
name: 'MySites',
data: data
}
]
});
}
Also you need proj4js library to plot points on the map, in case if that's your requirement as well.
Hope this helps !

Might, it can be useful.
Here is the solution for angular-highcharts:
1) Download the map from collection:
https://code.highcharts.com/mapdata/
2) Create a variable that equals to the content of this file and export it:
instead of
Highcharts.maps["custom/world"] = { ... content of the file ... }
use
const worldMap = { ... content of the file ... }
export default worldMap;
2) Import this map to your component (for world-map.ts):
import worldMap from './world-map';
3) use
chart: {
...
map: worldMap,
...
},
And, of course, don't forget to add a couple of lines to your module:
import { ChartModule, HIGHCHARTS_MODULES } from 'angular-highcharts';
import * as highmaps from 'highcharts/modules/map.src';
#NgModule({
...
providers: [
{ provide: HIGHCHARTS_MODULES, useFactory: () => [highmaps] }
],
...
})
About modules: https://www.npmjs.com/package/angular-highcharts#highmaps
Here is the working example:

Displaying array values in Bar chart of HighCharts

I am trying to display values which I am getting dynamically. In the below code I am trying to store the values in array and I am trying to use the array values in "series: data".
Nothing is getting displayed in the graph.
I know this is very simple question but I did not get any satisfactory answer when I googled it. Please help
var x = window.location.search.replace( "?", "" );
x = x.substring(3);
var array = x.split(","); // I am storing my dynamic values in this array
$(function () {
//alert(array); ----- I am able to see the values here
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Wireless Experience Meter'
},
subtitle: {
text: 'Sub - Time to Download'
},
xAxis: {
categories: ['Text'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Time (ms)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' ms'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: '#FFFFFF',
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Attempt 1',
//data: [635, 203, 200]
data : [array[0]] // I need to pass the variables here to get it displayed
}, {
name: 'Attempt 2',
//data: [133, 408, 698]
data : [array[1]]
}, {
name: 'Attempt 3',
//data: [973, 914, 4054]
data : [array[2]]
}]
});
});

You don't tell us what the variable array equals but since its generated from x.split(","), it's elements are going to be strings and not the numeric values Highcharts needs.
So convert it with parseInt or parseFloat:
var numericData = [];
for (var i = 0; i < array.length; i++){
numericData.push(parseFloat(array[i]));
}
...
series: [{
name: 'Attempt 1',
data : numericData
},
...

[array[0]] is not an array, that looks like console output not javascript. But [[0]] or [0] technically would be. However, since a call to array (array(0)) generates an array then I think you want data: array(0).
Outside shot at data : [array(0)] if you didn't show the example data correctly. I've never used HighCharts so I don't know what it's expected but I still go with data : array(0)
