I want to insert two buttons into the columns of the datagrid using Kendo UI.
Each element of the list contain two buttons example: EDIT and DELETE
I assume you using kendo ui and trying to have edit and delete button in each row this is how you can accomplish it by specifying a column like this .
{ command: ["edit", "destroy"], title: " ", width: "250px" }]
Please see the code snippet below taken from telerik sample . Here is the live dojo sample. The example below uses a popup editing. In case you are using inline editing look into this inline Editing Sample

I'm trying to update a highcharts highstock chart with live data from a json file on my server.
now I have a chart that gets its data from a json file (that I create with php that requests the data from my MySQL database) like so:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>OKcoin Price LTCCNY</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$.getJSON('json/lastTradesOkcoinLTCCNY.json', function(data) {
Highcharts.setOptions({
global: {
useUTC: false
}
});
// create the chart
$('#container').highcharts('StockChart', {
rangeSelector : {
selected : 1
},
title : {
text : 'OkCoin Price LTCCNY'
},
rangeSelector: {
buttons: [{
type: 'hour',

So far no problems, I get a chart from the json file. But of course it doesn't update if new data becomes available (only if I reload the page) .
What I want to do is after loading this chart, add live data to it as it becomes available.
something like this example, but instead of random data the chart will be updated with data from a (second) live updating json file on my webserver. The json file will be created by php (this part is working just fine) But I can't figure out how to add the data from the json file to the my existing highstock chart.
I also found
this this example on highcharts.com and that more or less does what I try to do, but I can't integrate the 'requestData' function into my existing chart.
So what I want to do is use the 'requestData' function from the second example with the high stock chart I already have. My second json file (with the live data) looks the same as in the second example (timestamp, price):
[1389022968000,173.3]
Can anyone help me a bit?
nevermind, I figured it out myself...
here's my solution:

$.ajax({

success: function(point) {
var series = chart.series[0],
shift = series.data.length > 2; // shift if the series is longer than 20
// add the point
chart.series[0].addPoint(eval(point), true, shift);
// call it again after one second
setTimeout(requestData, 10000);
},
cache: false
});
}
$(function() {
$.getJSON('../okcoin/json/lastTradesOkcoinLTCCNY.json', function(data) {
// set the allowed units for data grouping
var groupingUnits = [[
'minute', // unit name
[1,5,15,30] // allowed multiples

// create the chart

The getResource variable is visible only inside the success function
Move the code that you are using to create the chart to some function and call it inside the success function, it will be something like this:
var createChart = function(resources) {
var store = Ext.create('Ext.data.JsonStore', {
fields: ['name', 'data'],
data: resources
});
Ext.create('Ext.chart.Chart', {
renderTo: 'myExample',
width: 500,
height: 350,
animate: true,
store: store,
theme: 'Base:gradients',
series: [{ ....
.....
.....
.....
});
});
}
And then call it inside your success function
success: function(response){
getResources = Ext.decode(response.responseText);
createChart(getResources);
alert(JSON.stringify(getResources));
}
I'm trying to add 3 Y axis, so I'll have 1 Y axis for every data serie.
This is my JSON, which is valid:

The JS code
$(function() {
$.getJSON('testdata.php', function(data) {
// Create the chart
$('#container').highcharts('StockChart', {
title : {
text : 'Temperature'
},
yAxis: [{
title: {
text: 'A'
}
}, {
title: {
text: 'B'
}
}, {
title: {
text: 'C'
}
}, {
title: {
text: 'D'
}
}],
series: [{
type: 'line',
name: 'data1',
data: data1,
yAxis: 1,
}
}, {
type: 'line',
name: 'data2',
yAxis: 2,
data: data2
}, {
type: 'line',
name: 'data3',
yAxis: 3,
data: data3
}, {
type: 'line',
name: 'data4',
yAxis: 4,
data: data4
}]
});
});
});
However, the chart won't load as soon as I add multiple Y axis. What am I doing wrong?
yAxis starts with 0, not with 1, so you are trying to set last series to non existing series.
[{
...
} ,{
type: 'line',
name: 'data4',
yAxis: 4, // max is 3
data: data4
}]
Second issue is to change options to proper format (mistaken by series name):
[{
...
} ,{
type: 'line',
name: 'data4',
yAxis: 3,
data: data[3].data //
}]
It finally works now! Thank you!!

ok... i have tes your code just by copy paste to my firebug (of course with edit the json urls),
and i got an error.... This is because the program flow...
if it was your script, and put them in a single file, you specify a grid before the store
here code works for me no error...
