How to add php data into highchart js file in php - php

my code:
series: [{
name: 'Brands',
colorByPoint: true,
<?php
$models="SELECT * FROM purchase_info GROUP BY model_name";
$models_querry=mysql_query($models);
while($models_data=mysql_fetch_assoc($models_querry))
{
$model_name[]=$models_data['model_name'];
}
?>
data: [{
name: ['<?php echo join($model_name, ',') ?>'],
y: 56.33,
drilldown: 'Hero Honda'
}]
}],
In my project i'm using high charts, in that how can i add php data into that, i just collect all data and saved into one variable named as $model_name[], after that i pass the array value into data, but in that it will not spitted, all data's are echoed into single one.

Use ajax for that..see the script code
$.ajax({
type: "POST",
url: 'ajax.php',
success: function(data) {
a = jQuery.parseJSON(data);
i=0;
$.each( a.total_potential_score, function( key, val ) {
data1[i] = parseFloat(val);
i++;
});
rasterize_function(data1);
}
});
Ajax file look like this
$a[0] = "1";
$a[1] = "2";
$a1['total_potential_score'][0] = "1";
$a1['department_name'][0] = "aaaaa";
$a1['total_potential_score'][1] = "3";
$a1['department_name'][1] = "bbbbb";
echo json_encode($a1);
function for the highchart displayed here
function rasterize_function(data1) {
var seriesArray = [];
$.each( data1, function( key, val ) {
seriesArray.push({
name: "aaaa",
data: [val],
animation: false,
dataLabels: {
enabled: true,
rotation: -90,
color: '#FFFFFF',
align: 'right',
x: 4,
y: 10,
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
});
});
$('#container').highcharts({
chart: {
type: 'column',
width: 700,

How to create a highchart with 3 different series categories name

I currently new creating a highcart I just want to know if these possible in the highcart. I want to create a cart with 3 categories
3 Categories:
Low Priority
Medium Priority
High Priority
So if my categories is 3 so the bar is 3 also with different name and different datas.
In my console.log the data result shows.
My Output:
My Function Code:
$.getJSON('ajax/ams_sla_report_chart.php', function(data,name){
console.log(data);
var json_data = "";
var json_name = "";
var chart = new Highcharts.Chart({
chart: {
renderTo: 'containers',
type: 'column',
inverted: false
},
legend: {
layout: 'horizontal',
align: 'right',
verticalAlign: 'middle'
},
yAxis: {
title: {
text: 'SLA PERCENTAGE'
}
},
title: {
text: 'Priority Based on SLA'
},
series:[{
name:'Low Priority',
colorByPoint: true,
data:data[0]
},
{
name:'Medium Priority',
colorByPoint: true,
data:data[1]
},
{
name:'High Priority',
colorByPoint: true,
data:data[2]
},
]
});
json_data = chart.series.data = data;
function showValues() {
$('#alpha-value').html(chart.options.chart.options3d.alpha);
$('#beta-value').html(chart.options.chart.options3d.beta);
$('#depth-value').html(chart.options.chart.options3d.depth);
}
// Activate the sliders
$('#sliders_eng input').on('input change', function () {
chart.options.chart.options3d[this.id] = parseFloat(this.value);
showValues();
chart.redraw(false);
});
showValues();
});
Output must be:
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'SLA BASED ON PRIORITY AND PERCENTAGE OF HIT'
},
subtitle: {
text: 'Source: WorldClimate.com'

You need to preprocess your data to the format required by Highcharts:
var data = [
['Low Priority', 100, 9],
['Medium Priority', 100, 2],
['High Priority', 100, 1]
],
categories = [],
series = [];
data.forEach(function(arr) {
arr.forEach(function(el, i) {
if (i === 0) {
categories.push(el);
} else if (series[i - 1]) {
series[i - 1].data.push(el)
} else {
series.push({
data: [el]
});
}
});
});
Highcharts.chart('container', {
...
series: series
});

HighCharts with JSON Data from multiple php files

I am new to HighCharts. I am making a pie chart with the data (JSON) coming form multiple php files. So i have used nested ajax calls. But I am stuck at how to integrate it into the chart data.
$.getJSON("php/footprint1.php", function(data1) {
$.getJSON("php/footprint2.php", function(data2) {
$.getJSON("php/footprint3.php", function(data3) {
$.getJSON("php/footprint4.php", function(data4) {
$.getJSON("php/footprint5.php", function(data5) {
$.getJSON("php/footprint6.php", function(data6) {
chart.series[0].data[0][1] = data1.reponse.numFound;
});
});
});
});
});
});
The chart goes like this.
chart = new Highcharts.Chart({
chart: {
renderTo: 'place2',
type: 'pie'
},
title: { align: 'center', text: 'Foot-Prints Detected' },
plotOptions: {
pie: {
shadow: false,
center: ['50%', '50%']
}
},
legend: {
enabled: true,
layout: 'vertical',
align: 'right',
width: 250,
verticalAlign: 'middle',
useHTML: true,
},
tooltip: {
formatter: function() {
return '<b>'+ this.point.name +'</b>: '+ this.y +' %';
}
},
series: [{
name: 'Browsers',
data: [["BLOG",4],["PAID",4],["DIRECTORY",9],["WORDPRESS",7],["ADULT",7],["PHARMACEUTICALS",8]],
size: '100%',
innerSize: '75%',
showInLegend:true,

Highcharts xAxis doesn't get the right time format

I created a chart combined with datepicker. that gets data out of a SQL database with datetime, open, high, low, close for the selected date.
I tested every single way to format the xAxis so that the unzoomed tickinterval is 1 hour like 7:00 8:00 9:00...
And I want to be able to zoom in so that the smallest interval is 1 minute like 7:00 7:01 7:02...
First problem is, that the format always keeps looking like yyyy-mm-dd hh:mm:ss for every single point. After changing the tickInvterval it looked better but still wrong and the zoom function for an 1 minute interval was not possible.
After splitting database into single date and time columns I solved the date problem, but obviously highchart still doesn't realize that it is a timeaxis, because xAxis settings look like this: (should display hh:mm but the chart displays hh:mm:ss)
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
minute: '%H:%M'},
tickInterval: 60},
At least it's not the intention to split the database, because there should be a way that i can use to change the sql datetime into a javatime format during the query process.
I searched for days now, but didn't find the right answer... maybe because I'm too new to this stuff... :)
This is the code to generate the chart:
$(document).ready(function() {
Highcharts.setOptions({

?>
You can use tickPositioner which allows to calculate ticks, dynamically http://api.highcharts.com/highstock#xAxis.tickPositioner
Your tickInterval is very small. It is set to 60 milliseconds. If you want the tickInterval to be one minute you need to set it to multiply by 10k:
tickInterval: 60 * 10000
That should solve it because even though you are saying to use '%H:%M' your resolution is much smaller.
Edit:
So, a few things. See this jsFiddle.
You need to set a start time (always good practice) and you need to tell it how much time between data points if you do not provide data as {x, y}. To do this you do:
series: [{
pointStart: Date.UTC(2010, 0, 1),
pointInterval: 60000, //every minute there is data.
name: 'Realtime',
type: 'area',
data: [8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500, 8500]
}]
The important parts are pointStart and pointInterval. I also set the max zoom level to be one minute up in the chart: {} options:
maxZoom: 60000
Thank you so much, finally I got most functions and the problem was
options.xAxis.categories = json['datetime'];
BUT... :)
I'm recieving market data where some minute data are missing every single day, e.g. 7:00, 7:01, 7:03 and so on. and with an xAxis datetime format Highchart doesn't realize this and only counts up the time so that the last shown tick for example is 21:40 and not 22:00 as it should be.
That's why I wanted to recieve the x-values from the database datetime, which I obviously was not able to do.
Does anybody have an idea?

Convert Highchart to multiple y axis

As you can see this works as it should, however, I need this to function like the below example. It's important that I have the y axis showing the values and the zoom must work. I have tried to adapt the below code with my own data but I get the issue unresponsive script. I think my data could be too much for the chart to handle.

$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({

Can anyone help?

I think this is what you want: http://jsfiddle.net/mxrhS/
I did it by defining 3 yaxis, and then setting each series to use a different yaxis:
yAxis:[{opposite:false},{opposite:true},{opposite:true,offset:50}],
and
series: [{
name: 'Electric',
yAxis:0,

Bars does not show up when loading JSON encoded data from PHP in Highcharts

I am loading data stored in a MySQL Database.
The chart doesn't show up on the webpage, but it doesn't show any other warning.
My PHP webpage returns a JSON encoded header with the following information:
["John Doe","2","Jane Doe","3"]
The script that loads the information is the following:
var chart;
function requestData() {
$.ajax({
url:'includes/bin/get_leaders.php',
success: function(point) {
alert(point);
var series = chart.series[0],
shift = series.data.length > 20; // shift if the series is longer than 20
chart.series[0].addPoint(point, true, shift);
},
cache: false
});
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
events: {load: requestData}
},
title: {
text: 'Top Agents'
},
xAxis: {
type: 'int',
title: {text: null}
},
yAxis: {
min: 0,
title: { text: 'Sales this Week', align: 'low'}
},
tooltip: {
formatter: function() {
return ''+ this.series.name +': '+ this.y +' sales';
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -100,
y: 100,
floating: true,
borderWidth: 0,
backgroundColor: '#FFFFFF',
shadow: false
},
credits: {
enabled: false
},
series: [{
name: 'Sales' }]
});
});
});
Any clue what's going on?
Thank you!
Looks like you are passing in a ["string", "number", "string", "number"].
What you want is {2, 3} for your series and then for your xAxis to use a category list of {"John Doe", "Jane Doe"}.
