How to add data to a Tooltip in a echart graph

i have this bar graph made with echar, and i want to add information to the tooltip that it shows when you select a bar in the graph, how can i to do that?
this is the graphic code:
option: {
title: {
text: "Unidades que Necesitan Mantenimiento por Kilometro",
//subtext: "Living Expenses in Shenzhen",
},
tooltip: {
trigger: "axis",
axisPointer: {
type: "shadow",
},
},
grid: {
left: "3%",
right: "4%",
bottom: "3%",
containLabel: true,
},
xAxis: [
{
type: "category",
data: [],
axisTick: {
alignWithLabel: true,
},
},
],
yAxis: [
{
type: "value",
},
{
type: "value",
},
],
series: [
{
name: "Kilometraje Excedido",
type: "bar",
barWidth: "60%",
data: [],
},
],
},
here i load actually the information from my request, i want to load the information from Año_del_Modelo and Fecha_del_Ultimo_Servis also i want to add a label that says "Modelo", and "Ultimo Servis":
async obtenerUnidadesMantenimientoImportante() {
var respuesta;
this.url =
this.urlBase + "reporte/obtenerunidadesmantenimientoimportante";
const config = {
headers: {
Authorization: `Bearer ${sessionStorage.getItem("Token")}`,
},
};
respuesta = await this.$http
.get(this.url, config)
.then((response) => response.data);
var i = 0;
while (i < 9) {
this.modelos.push(respuesta[i].Año_del_Modelo);
this.ultMantenimientos.push(respuesta[i].Fecha_del_Ultimo_Servis);
this.option.xAxis[0].data.push(respuesta[i].Unidad);
this.option.series[0].data.push(
respuesta[i].Km_Restante_de_Proximo_Servis * -1
);
i++;
}
},

Convert json data to object

Good Day Developers!
I'm facing issue in JSON object received from MVC controller to AJAX success request.
The response which received is below.
[
{"name":"ERP Developer","value":2},
{"name":"Software Engineer","value":2},
{"name":"Dot Net Developer","value":2},
{"name":"Apex Developer","value":0},
{"name":"test","value":1}
]
But i want to make it like below.
{
"name": [
"ERP Developer",
"Software Engineer"
],
"Value": [
5,
10
]
}
Problem: Because i'm creating Bar chart using ECHARTS library but i want series name instead of number please see below image for reference.
function loadBarChart(data,title = "JobData",subtext = "Artistic Milliners") {
//var BarDBData = data;
var BarDBData = data;
//var BarDBData = JSON.parse('{"name":["ERP Developer","TEST"],"test":[5,10]}');
console.log(BarDBData);
var chartDom = document.getElementById('BarChart');
var myChart = echarts.init(chartDom);
var option;
option = {
title: {
text: title,
subtext: subtext
},
tooltip: {
trigger: 'axis'
},
toolbox: {
show: true,
feature: {
dataView: { show: true, readOnly: false },
magicType: { show: true, type: ['line', 'bar'] },
saveAsImage: { show: true }
}
},
calculable: true,
xAxis: [
{
type: 'category',
// prettier-ignore
//data: ["ERP Developer", "Software Engineer"],
data: BarDBData,
axisLabel: { interval: 0, rotate: 30 }
}
],
yAxis: [
{
type: 'value'
}
],
dataZoom: [
{
show: true,
start: 04,
end: 100
},
{
type: 'inside',
start: 44,
end: 100
},
{
show: true,
yAxisIndex: 0,
filterMode: 'empty',
width: 30,
height: '80%',
showDataShadow: false,
left: '93%'
}
],
series: [
{
name: "test",
type: 'bar',
data: BarDBData,
//data: [2.0, 4.9, 4, 9, 4],
itemStyle: {
color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
{ offset: 0, color: '#83bff6' },
{ offset: 0.5, color: '#188df0' },
{ offset: 1, color: '#188df0' }
])
},
markPoint: {
data: [
{ type: 'max', name: 'Max' },
{ type: 'min', name: 'Min' }
]
}
}
]
};
option && myChart.setOption(option);
}

you can just map through array and extract values into another array
const result = {}
const arr = [{"name":"ERP Developer","value":2},{"name":"Software Engineer","value":2},{"name":"Dot Net Developer","value":2},{"name":"Apex Developer","value":0},{"name":"test","value":1}]
arr.forEach(row => {
for (let i in row) {
if (result[i]) {
result[i].push(row[i])
} else {
result[i] = [row[i]]
}
}
})
console.log(result)

Just reduce() it into the desired shape:
const response = [
{"name":"ERP Developer","value":2},
{"name":"Software Engineer","value":2},
{"name":"Dot Net Developer","value":2},
{"name":"Apex Developer","value":0},
{"name":"test","value":1}
];
const mapped = response.reduce(
(acc,x) => {
acc.name.push( x.name );
acc.Value.push( x.value );
return acc;
},
{ name: [], Value: [] }
);

How to format returned string value of JSON with Ext JS?

I'm getting this JSON below and need to format code field' string value to some other text. For example 'TOTALPENDING' will render as "Pending Bonus" and 'TOTALLEFT' to "Current Bonus". How can i achieve to this?
{
"success": true,
"msg": "OK",
"count": 5,
"data": [
{
"bookerid": 103083420,
"code": "TOTALPENDING",
"totalcount": 1
},
{
"bookerid": 103083420,
"code": "TOTALLEFT",
"totalcount": 2
},
Data fetchs through ViewModel stores;
stores: {
bookStore: {
model: 'MyApp.model.base.BookStatModel',
autoLoad: true,
session: true,
proxy: {
url: MyApp.Globals.getUrl() + '/bonustrans/stat/book',
type: 'ajax',
reader: {
type: 'json',
rootProperty: 'data'
}
}
},

For this you need to use convert config inside of model.
In this FIDDLE, I have created a demo using grid, store and model. I hope this will help/guide you to achieve your requirement.

extjs 3.2.1 chart is not displaying

I am creating a pie chart in 3.2.1. and then I am adding this chart into field set. But it is not displaying chart into field set. Only blank white page is displaying. And in console "Uncaught TypeError: Error #1007" this error is showing.
Here is my code-
createChart: function(node, fieldSetId, KWTags) {
var store = new Ext.data.JsonStore({
fields: ['name', 'data'],
data: [{
"name": "Item-0",
"data": 5
}, {
"name": "Item-1",
"data": 7
}, {
"name": "Item-2",
"data": 3
}, {
"name": "Item-3",
"data": 6
}, {
"name": "Item-4",
"data": 2
}, {
"name": "Item-5",
"data": 8
}]
});
var chart = new Ext.chart.Chart({
width: 200,
height: 350,
animate: true,
store: store,
theme: 'Base:gradients',
series: [{
type: 'pie',
angleField: 'data',
showInLegend: true,

renderer: function(storeItem, item) {
this.setTitle(storeItem.get('name') + ' ate ' + storeItem.get('data') + ' cookies');
}
},
label: {

display: 'rotate',
//contrast: true,

});
return chart;

Displaying multiple Highcharts from single json

In this fiddle : http://jsfiddle.net/LLExL/5018/
I'm displaying a chart with dates on X axis and counts on Y axis.
I'm attempting to generalize this a little by displaying multiple charts using a single snippet of json. So have defined this modified json file :
[
{
"header": "test1",
"children": [
{
"date": "2015-01-02",
"count": "36"
},
{
"date": "2015-01-03",
"count": "29"
}
]
},
{
"header": "test2",
"children": [
{
"date": "2015-01-02",
"count": "36"
},
{
"date": "2015-01-03",
"count": "29"
}
]
}
]
Does Highcharts support this type of functionality out of box ? If so how it be achieved ? Each header element above is chart header.
fiddle code :
html :
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="width: 350px; height: 300px;"></div>
javascript :
var pointStart = new Date().getTime();
var jsonString = '[ {"date":"2015-01-02","count":"36"} , {"date":"2015-01-03","count":"29"} ]';
var myData = JSON.parse(jsonString);
var data = []
var combinedHeights=[]
$.each(myData, function(i, obj) {
var d = new Date(obj.date)
data.push([Date.parse(d), parseInt(obj.count)])
combinedHeights.push(parseInt(obj.count))
});
jQuery(document).ready(function() {
$('#container').highcharts({
chart : { type : 'line' },
title: {
text: 'test' // Title for the chart
},
subtitle : { },
legend : { enabled : true },
tooltip : { },
plotOptions : {

You can prepare parser, which puts a new div and create chart parsing data. The options can be common object, but using $.extend() is needed avoid using the same reference.
Parser:
var $chartGrid = $('#chart-grid'),
title = [],
serie,
date,
name;
$.each(json, function(i, item) {
name = 'container-' + i;
$chartGrid.append('<div id="'+name+'" class="chart"></div>');
serie = [{
data: []
}];
$.each(item.children, function(j, points) {
date = points.date.split('-'); //Date.parse doens't work in FF and IE
serie[0].data.push({
x: Date.UTC(date[0],date[1],date[2]),
y: parseFloat(points.count)
});
});
options.title.text = item.header;
options.series = serie;
$('#' + name).highcharts($.extend({}, options));
});
Example: http://jsfiddle.net/LLExL/5085/

try this out http://jsfiddle.net/Paulson/LLExL/5082/
var pointStart = new Date().getTime();
var jsonString = '[{"header":"test1","children":[{"date":"2015-01-02","count":"36"},{"date":"2015-01-03","count":"29"}]},{"header":"test2","children":[{"date":"2015-01-02","count":"29"},{"date":"2015-01-03","count":"36"}]}]';
var myData = JSON.parse(jsonString);
var data = []
var combinedHeights=[]
$.each(myData, function(i, obj1) {
var newData = [];
$.each(obj1['children'], function(i, obj2) {
