I have json data like this:
and I want to display the above date data as x-axis on my chart:
$(document).ready(function () {
getAjaxData(1);
var val = location.search.split('balai=')[1]
getAjaxData(val);
function getAjaxData(balai){
$.getJSON('src/json/proyek/progress-fisik.php', {balai: balai}, function(progressFisik) {
var chart1 = new Highcharts.Chart('progress_fisik', {
chart: {
renderTo: 'progress_fisik',
type: 'column',
},
title: {
text: ''
},
subtitle: {
text: ''
},
yAxis: {
min: 0,
max: 100,
tickInterval: 20,
allowDecimals: false,
title: {
text: ''
},
},
xAxis: {
type: 'datetime',
labels: {
formatter: function ( ){
return Highcharts.dateFormat('%d-%m-%Y');
},
},
},
tooltip:{
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.numberFormat(this.y, 2) +' %';
},
},
plotOptions: {
column: {
dataLabels: {
enabled: true,
format: '{point.y:,.2f}'+'%',
}
},
},
series:progressFisik,
});
});
}
});
I've spent a lot of time trying to solve this problem, but haven't gotten any results until now.
I hope someone is kind enough to help me on how I can improve my code above. any help I really appreciate. thanks.
You need to adapt your data to the format required by Highcharts. For example:
const series = progressFisik.map(dataEl => ({
name: dataEl.name,
data: dataEl.data.map((y, index) => [
new Date(dataEl.date[index]).getTime(),
y
])
}));

I want multiple graphs to be loaded on submit.
But its not showing any graph.
I have a problem on my HighCharts graph with JSON data. To explain a litle bit : I have a form, when I submit this form I send my data to my controller with Ajax, I treat them and I return the new array of data for my highcharts graph, but when I use setData function with my new array the graph disappear and the new data aren't displayed.
Here is my ajax function and my test to set the new data into my graph :
$('#gestion .l-gestion-content-form #form-add-informations .btn-validation').click(function(e) {
e.preventDefault();
var chart = $('#hightchart-graf').highcharts();
var dataActionForm = $('#form-add-informations').attr('action').split("/");
var url_ajax = Routing.generate('gestion_view', { dossier: dataActionForm[4], fille: dataActionForm[5] });
var formData = $('#form-add-informations').serializeArray();
$.ajax({
type: "POST",
dataType: 'json',
url: url_ajax,
data: formData,
success: function(msg)
{
console.log(msg['infosArray']);
var test = [ msg['infosArray'].join(',') ];
console.log(test);
console.log('---------------------------------------------');
console.log(msg.infosArray);
var test2 = msg.infosArray.join(',');
var test3 = test2.replace('"', '');
console.log(test2);
chart.series[0].setData( [ msg.infosArray.join(',') ] );
//[ {{ msg.infosArray | join(',') }} ]
},
error: function(XMLHttpRequest, textStatus, errorThrown)
{
alert('ERROR');
}
});
});
All my data are stored in the array named msg.infosArray or msg['infosArray'] and the first console.log return an array like this :
["[Date.UTC(2015,11,23),80.00]", "[Date.UTC(2015,11,23),89.00]", "[Date.UTC(2015,11,25),150.00]", "[Date.UTC(2015,11,28),45.00]", "[Date.UTC(2015,11,29),169.00]", "[Date.UTC(2015,11,29),189.00]", "[Date.UTC(2015,11,29),196.00]", "[Date.UTC(2015,11,29),200.00]", "[Date.UTC(2015,11,29),205.00]", "[Date.UTC(2015,11,30),210.00]", "[Date.UTC(2015,11,31),225.00]", "[Date.UTC(2016,0,1),250.00]", "[Date.UTC(2016,0,2),25.00]", "[Date.UTC(2016,0,3),259.00]", "[Date.UTC(2016,0,5),25.00]", "[Date.UTC(2016,0,6),250.00]", "[Date.UTC(2016,0,7),25.00]", "[Date.UTC(2016,0,8),250.00]", "[Date.UTC(2016,0,9),25.00]", "[Date.UTC(2016,0,10),250.00]", "[Date.UTC(2016,0,11),25.00]", "[Date.UTC(2016,0,12),250.00]", "[Date.UTC(2016,0,25),25.00]", "[Date.UTC(2016,0,26),250.00]"]
So I tried to escape " and ' or to join the array but nothing work. Somebody know how can I set the new data, or where I commited a fault ?
Maybe i got a bad response from my Controller ?
Thanks
You need to convert string of javascript code to array of javascript.
I wrote a demo version which converts string to javascript code. and draws chart as expected. Do not focus on the labels it's a dummy data.
JSFiddle Demo
$(function () {
var data = ["[Date.UTC(2015,11,23),80.00]", "[Date.UTC(2015,11,23),89.00]", "[Date.UTC(2015,11,25),150.00]", "[Date.UTC(2015,11,28),45.00]", "[Date.UTC(2015,11,29),169.00]", "[Date.UTC(2015,11,29),189.00]", "[Date.UTC(2015,11,29),196.00]", "[Date.UTC(2015,11,29),200.00]", "[Date.UTC(2015,11,29),205.00]", "[Date.UTC(2015,11,30),210.00]", "[Date.UTC(2015,11,31),225.00]", "[Date.UTC(2016,0,1),250.00]", "[Date.UTC(2016,0,2),25.00]", "[Date.UTC(2016,0,3),259.00]", "[Date.UTC(2016,0,5),25.00]", "[Date.UTC(2016,0,6),250.00]", "[Date.UTC(2016,0,7),25.00]", "[Date.UTC(2016,0,8),250.00]", "[Date.UTC(2016,0,9),25.00]", "[Date.UTC(2016,0,10),250.00]", "[Date.UTC(2016,0,11),25.00]", "[Date.UTC(2016,0,12),250.00]", "[Date.UTC(2016,0,25),25.00]", "[Date.UTC(2016,0,26),250.00]"];
//t = t.map(function(element){return eval(element);});

I want to display Text for my ForigenKey columns instead of numeric values. There are a lot of examples to retrieve TextMember by comparing ID but they are not working in my case. I just started to use Kendo ui so dont know much about it
Here is the code :
$(document).ready(function () {
dataSource1 = new kendo.data.DataSource({
transport: {
read: {
url: "Data/AttendanceCode/GridSelect.php",
dataType: "json",
},
update: {
url: "Data/AttendanceCode/GridUpdate.php",
dataType: "json",
type:"GET"
},
destroy: {
url: "Data/AttendanceCode/GridDelete.php",
dataType: "json",
type:"POST"
},
create: {
url: "Data/AttendanceCode/GridInsert.php",
dataType: "json",
type:"POST"
},
},
schema: {
data: "data",
model: {
id: "AttendenceID",
fields: {
AttendenceID : { editable: false, nullable: true },
TeacherID: { field: "TeacherID", defaultValue: "EIIT0002" },
}
}
},
});
$("#grid").kendoGrid({
dataSource: dataSource1,
pageSize: 10,
pageable: {
refresh: true,
pageSizes: true
},
editable:{ mode : "popup" },
height: 400,
filterable: true,
columnMenu: true,
sortable: true,
reorderable: true,
resizable: true,
toolbar: ["create"],
columns: [
{ field:"AttendenceID", title: "Attendence ID", width:"130px" },
{ field: "TeacherID", title:"Teacher", width: "100px" , editor: TeacherDropDownEditor, template: "#=getTeacherName(TeacherID)#" },
{ command: ["edit", "destroy"], title: "Action", width: "210px" }],
});
});
Teacher DropDown DataSource
teacher = new kendo.data.DataSource({
transport: {
read: {
url : "Data/Teacher.php",
dataType: "json" }
},
schema: {
data : "Teacher"
}
});
// Teacher Editor
function TeacherDropDownEditor(container, options) {
$('<input data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
dataTextField: "TeacherName",
dataValueField: "Service_NO",
dataSource: teacher
});
}
Different approaches i found and tried to Get Teacher Name
1 -
function getTeacherName(value) {
var text = "";
$.each(teacher, function () {
if (this.Service_NO == value) {
text = this.Name;
return false;
}
});
return text;
}
2 -
function getTeacherName(teacherID) {
for (var idx = 0, length = teacher.length; idx < length; idx++)
{
if (teacher[idx].Service_NO === teacherID)
{t = teacher[idx].Name;}
}
return t;
}
3 -
function getTeacherName(teacherID) {
$.each(teacher, function(key, val) {
if(val.Service_NO == tID){
t = val.Name;
}
});
return t;
}
It seems like dataSource (teacher) is not having any value.
PHP code is working perfectly.
Please Help if you have any idea whats wrong with my code.
Thanks !!
You are right, teacher DataSource does not have any data because you are defining how to get the data (that's what you do with the DataSource) but you are not reading it.
Add:
teacher.read();
for manually forcing the data read.
NOTE: This is something that happens magically when you have a Grid, ListView,... because these widget do it for you but this time, for displaying your grid you need to read it in advance since it is invoked from a JavaScript function (KendoUI grid code doesn't know anything about what you have in the function getTeacherName other than the name).
you should config your field:
{ field: "nu_status", title: 'Status', values: [ { text: "Active", value: 1 }, { text: "Inactive", value: 0 }]},
I'm trying to create a chart using data from my database calling json, but its not showing the results in the chart.
Here's my code so far:
$(document).ready(function() {
function requestData() {
$.ajax({
url: 'data.php',
datatype: 'json',
success: function(data) {
alert(data);
chart.series[0].setData(data[0]);
},
cache: false
});
}
var chart;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
events: {
load: requestData
}
},
xAxis: {
},
yAxis: {
title: {
text: 'Value'
}
},
series: [{
name: 'Random data',
data: []
}]
});
});
And here's my data.php code
$query = "SELECT tiempo,Fp1Ref
FROM GraficaEEG limit 10";
$data = mysqli_query($dbc, $query);
$i=0;
while($row = mysqli_fetch_array($data)) {
$row['tiempo'] = (float) $row['tiempo'];
$rows[$i]=array($row['tiempo'],(float)$row['Fp1Ref']);
$i++;
}
echo json_encode($rows);
The data i receive is this:
[[0,3001],[0.005,4937.22],[0.01,4130.55],[0.015,4213.15],[0.02,4010.61],[0.025,3914.34],[0.03,3785.33],[0.035,3666.13],[0.04,3555.25],[0.045,3447.77]]
So i think is the proper way to pass data for the chart, so i don't quite get whats wrong, thank you in advance.
I think the problem is that when your requestData() function is fired the chart variable still isn't fully built and doesn't know it has the series property.
To fix this, instead of chart in your requestData() function, reference this (which means the chart object in that context).
I tried this out in jsfiddle here http://jsfiddle.net/elcabo/p2r6g/.
Also post the js code below.
$(function () {
$(document).ready(function() {
//Function bits
function requestData(event) {
var tiemposAlAzar = [[10,20],[20,50]];
//The 'this' will refer to the chart when fired
this.series[0].setData(tiemposAlAzar);
};
var chart;
//Chart bits
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
events:{
load: requestData
}
},
xAxis: {},
yAxis: {
title: {
text: 'Value'
}
},
series: [{
name: 'Random data',
data: []
}]
});
});
});
This url may help you to create dynamic highchart that need to pull data from database.
In json.php code you can put your sql query and replace static array to dynamic array
http://www.kliptu.com/free-script/dynamic-highchart-example-with-jquery-php-json
The example also shows how to manage multiple series with json.
And tooltips with all series data at mouse point.
You can modify example as per your script requirement.
