How to open a page when highcharts stacked bar is clicked? - javascript

I am creating a stacked bar chart with help of highcharts.
When I click on any part of bar I want to open a new page that displays containing data. How can I achieve this?
As shown in this image the graph is not stacked as it should be. It is displayed as different three vertical bars. How can I fix this?

Drawing a dynamic Mixed Bar and Line chart with HIghchart.js with socket.io for live data

I am trying to draw a dynamic, mixed bar and line graph using Highchart.js. I am getting live data to my webpage using socket.io (I'm using Flask as my webserver so using Flask-socketIO).
I am able to print the data coming to my webpage using console.log, but I am missing something for which it is not rendered in the chart.
I am trying to add xAxis as well as both the Series value.

It's a problem with displaying only one point at a time with addPoint(point, redraw, shift, animation) and setting shift=true. That will remove previous point and chart will look empty.
Simple solution is to use:
series1.addPoint(y, false, false, false);
series2.addPoint(z, false, false, false);
myChart.redraw();

How to change the bar chart values from static to dynamic

I have a code for a bar chart and it is working well but this code has static values but I want to take the values from a server and every time have a different chart (I mean I dont want to give any values in the code).How can I make that?
This is the code:
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.1.0.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; max-width: 800px; height: 400px; margin: 0 auto"></div>
<script>
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Top 10 HashTags'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Number of repeated hashTags ',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [ {
name: 'Year 2012',
data: [1052, 954, 4250, 740, 38]
}]
});
});
</script>
A little example to you. The first column is the xAxis and the others, series. I hope this help you.:
<?php
$sql5 = mysqli_query($bd,'SELECT tx_rend_escolas.ano, tx_rend_escolas.ap_med, tx_rend_escolas.rep_med, tx_rend_escolas.abd_med FROM tx_rend_escolas WHERE tx_rend_escolas.fk_cod_entidade = 21438200 ORDER BY tx_rend_escolas.ano ASC;') or die(mysqli_error());
$linhas5 = mysqli_num_rows($sql5);
$proc4 = array();
$proc5 = array();
$proc6 = array();
$proc7 = array();
while ($docs = mysqli_fetch_assoc($sql5)) {
$proc4[] = "'".$docs['ano']."'";
$proc5[] = $docs['ap_med'];
$proc6[] = $docs['rep_med'];
$proc7[] = $docs['abd_med'];
}
$proc4 = implode(",", $proc4);
$proc5 = implode(",", $proc5);
$proc6 = implode(",", $proc6);
$proc7 = implode(",", $proc7);

Highcharts - Multiple pie charts from json

Highcharts - Multiple pie charts from json
Let's say I have a server with 4 hard drives. How do I show 4 pie charts, one for each hard drive? It works if the chart type is stacked column (code below).
JSON produces this output:
[{
"name":"Drive",
"data":["C:","D:","E:","F:"]},{
"name":"Free",
"data":[673869,2267920,105627,307096]},{
"name":"Used",
"data":[94029,2264810,6373,104]
}]
And my script code (for stacked column):

Thank you for any suggestions.
You can iterate on each json item and create new div (by for example append) and init chart.
What is important, all values in data should be numbers, not strings like you have.
Example:
http://jsfiddle.net/9ov3en2t/
$(function () {
var json = [{
"name": "Drive",
"data": ["C:", "D:", "E:", "F:"]
}, {
"name": "Free",
"data": [673869, 2267920, 105627, 307096]
}, {
"name": "Used",
"data": [94029, 2264810, 6373, 104]
}];
var each = Highcharts.each,
$charts = $('#charts');
each(json,function(item, i) {
$charts.append('<div id="container' + i + '"></div>');
var $chart = $('#container' + i);
$chart.highcharts({
chart:{
type:'pie'
},
series:[{
name: item.name,
data: item.data
}]
});
});
});

<h1>My First HighStock Chart!!!!</h1>
<b>Your name: </b> <input type="text" id="namefield">
<button id="submitbutton" type="button">Submit to server!</button>
<div id="output"> </div>
<br />
</body>
</html>
I did a
document.write(output)
and copyied the output to the jsfiddle at this address:
http://jsfiddle.net/gsaray101/rmL1573f/
it works there so I am assuming the data is accurate, any ideas what might be happening?
I resolved this problem by using JSON.parse() function in the ui as follows:
var data=output;
data=JSON.parse(data);

highstock conflict with jquery.ba-resize.js and jquery.flot.resize.js

after hours of troubleshooting about why my chart is not loading, i found using jquery.ba-resize and jquery.flot.resize concurrently with highstock in one page cause this error:
uncaught typeerror: cannot read property 'width' of undefined
currently im tring to integrate one of highstock examples into my page, which could be found at highstock demos.
any idea on how to fix this?
thanks

Looks like that 'resize' library overwrites some jQuery function, which doesn't work the same way anymore.. ? In that case I advice to use Highcharts standalone version, see: http://jsfiddle.net/CFPqG/1/
