Highchart - I have to refresh the page to see new data

Below is the chart code, my problem is JSON needs to be used to grab updated data.
I dont want the whole chart to be re-render, but instead only the candles (add the new ones).
I guess there has to be a loop looking every sec in the new data by looping the JSON and create a chart.update?
Would love a answer from anyone with how i should solve this with code!

Looking at the highcharts api quickly on google, you may need an event property followed by load property, and your logic, which would probably include something like
chart: {
events: {
load: function () {
// here's how you would access your series
var series = this.series[0];
setInterval(function () {
//modify your series here.
}, 1000);
}
}
}

How to reduce HighStock chart gap between candles?

I'm using candlestick chart of HighChart-HighStock. I want to reduce the gap between candlesticks. It's not so bad when it's on a wide range zoom. But when I zoomed the chart a lot, the padding between candle makes me annoyed because they are too wide apart.
I tried setting pointPadding of plotOption&xAxis to 0, but nothing happened. How can I shrink this gap?
Zoomed chart - too wide gap between candlestick
Wide view chart - not so bad
Highcharts.stockChart('container', {
// title: { text: '---'},
rangeSelector: {
buttons: [
// { type: 'hour', count: 1, text: '1h' },
{
type: 'day',
count: 1,
text: '1d'
},
// { type: 'all', count: 1, text: 'All' }
],

//inputEnabled: true
},

You need to set the series.pointPadding combined with series.groupPadding (equal to zero) to achieve the expected effect. Here is the example: https://jsfiddle.net/ahxrk5zq/
series: [{
type: 'candlestick',
name: 'AAPL Stock Price',
data: data,
groupPadding: 0,
pointPadding: 0.04,
dataGrouping: {
units: [
[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]
]
}
}]

How to set interval points on the x-axis in HighCharts?

I have a bubble chart and would like to set the interval points on the x-axis to a predefined list. For example, the list is [90, 100, 103, 108, 110, 112, 116, 120]. Here's my code:
jQuery("#center_col_wrapper").highcharts({
chart: {
type: 'bubble'
},
title: {
text: 'Highcharts Bubbles'
},
xAxis: {
allowDecimals: false,
title: {
text: "BUBBLE CHART"
},
categories: ['90', '100', '110']
},
yAxis: {
title: {
text: ""
},
labels: {
enabled: false
}
},
series: [
{
name:"S1", data: [[100,10,87]]
},
{
name:"S2", data: [[100,11,87]]
},
{
name:"S3", data: [[110,12,87]]
},
{
name:"S4", data: [[110,13,87]]
}
]
});
Here's my jsfiddle: http://jsfiddle.net/mLP7U/

You can specify
minTickInterval: 10,
min: 90,
within your xAxis configuration.
See http://api.highcharts.com/highcharts#xAxis.min
and http://api.highcharts.com/highcharts#xAxis.minTickInterval
for explanations on these items. This will make only the 90, 100, and 110 labels appear on your x axis

So I was able to do this using formatter function in labels. I set min to 0, max to 5, and tickInterval to 1. An array was defined and formatter used this array to choose the appropriate label.
var labels = ["70", "90", "100", "110", "130", "145"];
jQuery("#container").highcharts({
chart: {
type: 'bubble'
},
title: {
text: 'Highcharts Bubbles'
},
xAxis: {
allowDecimals: false,
title: {
text: "Change"
},
tickInterval: 1,
min: 0,
max: 5,
labels: {
formatter: function() {
if (labels[this.value]) {
return labels[this.value]
}
return "e"
}
}
},
yAxis: {
gridLineColor: "#ffffff",
title: {
text: ""
},
labels: {
enabled: false
},
tickInterval: 1,
min: 0,
max: 5
},
series: [
{
name:"A", data: [[2,1,87]]
},
{
name:"B", data: [[2,2,87]]
},
{
name:"C", data: [[2,3,87]]
},
{
name:"D", data: [[4,1,87]]
}
]
});

Highstock when multiple lines share a y axis one line is drawn at an offset

I am using Highstock/Highchart and if I draw two lines on a graph, who share a single Y axis, one of the lines isn't displayed on the Y axis properly. It is offset to higher values. For example, a value is 120 but the dot shows up on the 200 line. I would post a pic but I can't yet.
I have tried setting the Y axis max by the highest value but the line goes off the chart because it's still rendered with an offset.
Here is my config for the chart :
$scope.chartConfig = {
options: {
style: {
fontSize: '12px'
},
chart: {
alignTicks: true,
type: 'spline'
},
rangeSelector: {
inputEnabled: true, //$('#container').width() > 480,

]]
}
}
],

}
},
credits: {

}
};
In the HTML:
<highchart id="chart" class="hiChart-container" config="chartConfig"></highchart>
And all I change is the data and series name to update the chart...
I am only importing Highstock and using Highchart-ng.
I cannot do var chart = new Chart($scope.chartConfig) because my javascript framework is AngularJS and hence we are using Highchart-ng
How do I adjust the lines to be scaled to the Y axis?

Highcharts Crosshairs not working

I have what I'd consider a relatively simple Highcharts chart that I want to use shared crosshairs, but for some reason, I can't get my tool tip to work properly. Here is my javascript code:
var myChart = new Highcharts.Chart({
chart: {
renderTo: 'container',
width: '675',
height: '400',
},
toolTip: {
crosshairs: {
width: 2,
color: 'gray',
dashStyle: 'shortdot'
},
shared: true,
enabled: true
},
xAxis: {
title: {
text: 'Date',
align: 'middle',
margin: 15,
},
reverse: false,
type: 'datetime',
opposite: false,
},
yAxis: [{
title: {
text: '% Change',
align: 'middle',
margin: 15,
},
reverse: false,
opposite: false,
},
{
title: {
text: 'actual amount',
align: 'middle',
margin: 15,
},
reverse: false,
opposite: true,
}, ],
title: {
text: 'Comparison Chart',
align: 'center',
margin: 15,
},
series: [{
pointInterval: 86400000,
name: 'Your actual amount',
type: 'spline',
yAxis: '1',
color: '#4572A7',
data: [[1291248000000, 4140],
[1291334400000, 342],
[1291420800000, 56],
[1291507200000, 58],
[1291593600000, 712],
]},
{
pointInterval: 86400000,
dashStyle: 'ShortDashDot',
name: 'Other\'s %',
type: 'spline',
yAxis: '0',
color: '#89A54E',
data: [[1291248000000, 47.02],
[1291334400000, -28.68],
[1291420800000, -59.98],
[1291507200000, 182.14],
[1291593600000, -12.81],
]},
{
pointInterval: 86400000,
dashStyle: 'ShortDash',
name: 'Your %',
type: 'spline',
yAxis: '0',
color: '#AA4643',
data: [[1291248000000, 246.73],
[1291334400000, -91.74],
[1291420800000, -83.63],
[1291507200000, 3.57],
[1291593600000, 1127.59],
]},
],
});

The only thing I spotted was that in the JSON above you've put toolTip whereas in the highchart examples it's tooltip (all lower case).
