ohlc.push([

Why this code dont't work ?
Don't work:
- Two panes, candlestick and volume
- OHLC
- 1.7 million points with async loading...
The issue is in the "date" in csv or something else ... ?

Hi
There is issue with my csv export for gauge chart.
when I export a chart as a csv it downloades the chart as first column with value 0.
Is there any way to avoid that and get only one column for gauge type charts.
currently my csv contains data like below after downloading :
e.g. Micromarket | total stock (%)
0 | 18.41
But i want data should be like this after download :
e.g. total stock (%)
18.41
Please refer my below JS fiddle link for reference.

I have a Highcharts chart which gets it's data from a JSON request.
function slowips(target){
var options = {
chart: {
renderTo: target,
type: 'spline',
borderColor: '#0072C6',
borderWidth: 3
},
title: {
text: 'Responsetime'
},
subtitle: {
text: 'Nr.1 is slowest'
},
legend: {
enabled: true,
layout: 'vertical',
align: 'right',
verticalAlign: 'middle'
},
yAxis: {
title: {
text: 'Milliseconds'
},
min: 0
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
month: '%e. %b',
year: '%Y'
},
labels: {
enabled: true,
},
minorTickLength: 0,
tickLength: 0,
},
plotOptions: {
spline: {
animation: false,
enableMouseTracking: false,
marker: {
enabled: false
}
}
},
series: [{}]
};
$.getJSON('graphs/test.php', function(data) {
options.series = data;
var chart = new Highcharts.Chart(options);
});
}
slowips();
This is an example JSON input:
[ { "name":"sddf", "data": [ ["2013-02-01 00:01:00", 2 ], ["2013-02-02 00:02:00", 2.55 ] ] } ]
Also tried:
[ { "name":"sddf", "data": [ [Date.UTC(12, 3, 09), 2 ], [Date.UTC(12, 3, 10), 2.55 ] ] } ]
The first JSON example renders a chart, but with incorrect X axis data. The second JSON does not render the chart.
Please help out!
You need to use timestamps, so when you load first JSON, then you need to parse it by Date.UTC() / Data.parse(), but functions cannot be places in json inside (as you have in second example).
I have a highcharts bargraph whose values are received from json whose format is as follows:
"bargraph":
[
{
"categories": "['S', 'M', 'T', 'W', 'T', 'F']",
"series1": "[800, 1100, 80, 1800, 1600, 2000]",
"series2": "[800, 1100, 80, 1800, 1200, 800]"
}
]
How can i embed those values for my bargraph in angularJS
HTML Code:
<div id="bargraph" bargraph={{bargraph}}><\div>
Directive:
angular.module('example').directive('bargraph', function () {
element.highcharts({
xAxis: [
{
categories: [] //embed categories value here
},
series: [
{
name: 'series1',
data: [] //Embed series1 data here
},
{
name: 'series2',
data: [] //Embed series2 data here
}
]
})
})
Please provide a suitable way to embed the data from json.
Here is a directive i copied and pasted from my webapp it is how i render highcharts using a directive NOTE: not all of this directive is applicable to you and some of it is specific to what i needed but you get the idea.
lrApp.directive('chart', function () {
return {
restrict: 'E',
template: '<div></div>',
transclude: true,
replace: true,
link: function (scope, element, attrs) {
var chart = null;
var chartsDefaults = {
chart: {
renderTo: element[0],
type: attrs.type || null,
height: attrs.height || null,
width: attrs.width || null,
},
colors: scope.$eval(attrs.colors) || null,
title: {
style: {
display: 'none'
}
},
xAxis: {
//categories: ['{"-7 days"|date_format}','{"-6 days"|date_format}','{"-5 days"|date_format}','{"-4 days"|date_format}', '{"-3 days"|date_format}', '{"-2 days"|date_format}', '{"-1 day"|date_format}', '{$smarty.now|date_format}'],
categories: scope.$eval(attrs.dates) || null,
gridLineDashStyle: 'ShortDot',
gridLineColor: "#C0C0C0",
gridLineWidth: 1,
labels: {
y: 27
}
},
yAxis: {
title: {
text: null
},
min: 0,
gridLineDashStyle: 'ShortDot',
gridLineColor: "#C0C0C0",
gridLineWidth: 1
},
credits: {
enabled: false
},
legend: {
enabled: false
},
plotOptions: {
series: {
shadow: false,
lineWidth: 3
}
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
this.x + ': ' + this.y + '</b>';
}
}
};
//Update when charts data changes
scope.$watch(attrs.value, function (newVal, oldVal) {
if (!newVal.length) return;
// We need deep copy in order to NOT override original chart object.
// This allows us to override chart data member and still the keep
// our original renderTo will be the same
var deepCopy = true;
var newSettings = {};
chartsDefaults.series = newVal;
chartsDefaults.colors = scope.$eval(attrs.colors);
chartsDefaults.xAxis.categories = scope.$eval(attrs.dates);
console.log(chartsDefaults);
chart = new Highcharts.Chart(chartsDefaults);
});
}
}
});
and this is how it used it obviously you would change "line" to bar:
<chart value="stats.sets" dates="stats.days" colors="stats.colors" type="line"></chart>
I have a problem with my HighStock, I need another series from JSON.
My code in get_json.php
include('config.php');
$cp = $_REQUEST["c_prot"];
$r=("SELECT * FROM data WHERE cp='$cp'");
$result=mysql_query($r);
while($row = mysql_fetch_array($result)){
$date= strtotime($row['cas'])*1000; // timestamp
$values=hexdec($row['data']); // series1
$val=hexdec($row['src']); // series2
$array[]=array($date, $values,$val); //output array
}
echo json_encode($array);
JSON output is in correct format: [1364852734000, 557, 2884],....
But problem is, that I didn't find how to add second series from JSON to Highstock code
I would like to display in chart x-axis: timestamp
y-axis: series1->data
series2->src
chart now displays only on x-axis timestamp and on y-axis data...but series2 doesn't work:/
High Stock code:
<script>
$(function () {
$.getJSON('http://localhost/vojto/get_json.php?c_prot=<?=$_REQUEST['
c_prot '];?>', function (data) {
// Create the chart
$('#container').highcharts('StockChart', {

var s = '<b>' + Highcharts.dateFormat('DateTime ' + '%d-%m-%y ' + '%H:%M:%S', this.x) + '</b>';
$.each(this.points, function (i, point) {
s += '<br/>Data value : ' + point.y;
});
/* formát 23-04-13 09:34:27 */
return s;
}
},
});
});
});
</script>
In you script:
$array = [];
while($row = mysql_fetch_array($result)){
$date= strtotime($row['cas'])*1000; // timestamp
$values=hexdec($row['data']); // series1
$val=hexdec($row['src']); // series2
$array[0][]=array($date, $values); //output array
$array[1][]=array($date ,$val);
}
You need paste values to appropriate series index. In other words you can prepare your $array() and add point to one of series. To be honest I have no data so It is only concept.
Please help,
I have only known about highcharts, Json and Jquery for 5 days. I have a Json file with info about 3 sets of results. I am trying to put 3 different lines on a highcharts chart. I do not know the syntax for this. i know that calling the options object allows you to add series and categories. I do not know the syntax to accomplish this
