highstock charts - button for date range - highcharts

in my application I use angular Highstock for charts. I have a lot of data (many millions), and now i want to put the existing buttons for set date range (1week, 1 month, 3 months, 1year, all), but also to click on any button to send a new request to the server to not accumulating data. Example, if pressed button "one week", that only the server retrieves the data for one week, if you click on a button to one month, to take data for a single month. I do not want to call unnecessary data, and that the server slows down, if I'm looking for data for one month, and the server comes back to me all data. Here is the code. Thanks in advance

Thnx to #Grzegorz Blachliński i fix this. here is code
$scope.chartConfig1 = {
xAxis: {
ordinal: false,
//za dodat date range postavit events i range selectors
events : {
afterSetExtremes: getDateRange //here i add my custom function
}
},
yAxis: {
plotLines: [{
color: '#FF0000',
width: 1,
value: 11.50,
label: {text: '11.50'}
}]
},
options: {
chart: {
zoomType: 'x',
backgroundColor: 'rgba(255, 255, 255, 1)',
polar: true,
type: 'line',
borderRadius: 5
},
legend: {
enabled: true
},
rangeSelector: {
selected : 0, //here i defined default range
enabled: true,
inputStyle: {
color: 'black'
}
},
navigator: {
enabled: true
}
},
series: [],
title: {
text: 'Solar and Battery voltage average'
},
useHighStocks: true
},
$scope.chartConfig1.series.push({
id: 1,
name: "Solar voltage average",
data: $scope.data[0],
tooltip: {
valueDecimals: 2
}
},   {
id: 2,
name: "Battery voltage average",
data: $scope.data[1],
tooltip: {
valueDecimals: 2
}
}
);
and here is my custom function
getDateRange = function (e) {
var date1 = new Date(e.min);
var date2 = new Date(e.max);
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24));
$http.get(serviceBase + 'aaaaa/aaaaaa/' + $stateParams.klupaID + '/aaaaaaa?days=' + diffDays, function(data){
//ukoliko buden dodavat još koji config obavezno dodat broj koliko ih ima na i<=8
for (i=1; i<=8; i++){
$scope.chartConfigString = 'chartConfig' + i;
$scope.chartConfigString.series[0].setData(data);
$scope.chartConfigString.hideLoading();
}
});
};
Now i have another problems, i want to have four selectors (buttons), 1months, 3months, 1year and ALL. I set default range, when open app, on 1month, and here is problem. Buttons for another range is disabled, beacause i get data from url only for one month. I want to have enabled all buttons for select any range. Thnx

Column chart with categorised Y axis

I'm trying to assign categories to the Y Axis on a column chart. I've tried using categories but this causes a peculiar result with the columns not reaching the X Axis, and the values being incorrect
https://jsfiddle.net/fmgLa5h4/1/
I've tried various other properties to correct this but to no avail.
I've also tried using labels.formatter, which gets a slightly more desirable result but with the labels aligned to the ticks - again I've tried other ways to correct this without success
https://jsfiddle.net/fmgLa5h4/2/
You can try to mapping the data using data.seriesMapping and set your own dataLabels or categories, take a look at this example:
var categories = ['A', 'B', 'C', 'D', 'E'],
yAxisLabels = ['10', '20', '30', '40', '50'];
Highcharts.chart('container', {
data: {
csv: document.getElementById('data').innerHTML,
seriesMapping: [{
// x: 0, // X values are pulled from column 0 by default
// y: 1, // Y values are pulled from column 1 by default
label: 2 // Labels are pulled from column 2 and picked up in the dataLabels.format below
}]
},
chart: {
type: 'column'
},
title: {
text: 'Daily runs'
},
xAxis: {
minTickInterval: 24 * 36e5
},
yAxis: {
labels: {
formatter: function() {
return yAxisLabels[this.value] + ', ' + this.value || '';
},
},
tickInterval: 1,
max: categories.length - 1,
},
legend: {
enabled: false
},
plotOptions: {
series: {
dataLabels: {
enabled: true,
format: '{point.label}'
},
}
}
});
For formatting data tables, yAxis.labels.formatter is a good option. It is possible that your data will need to be formatted before you map it.
Sample concept:
data = data.replace(/\r\n/g, '\n') // Unix
.replace(/\r/g, '\n') // Mac
.split('\n');
data.forEach(function(row, i){
if (i) {
row = row.split(',');
data[i] = row.concat([
categories.indexOf(row[1]),
categories.indexOf(row[3])
]).join(',');
}
});
data = data.join('\n');
Live demo:
https://jsfiddle.net/BlackLabel/g5svkrac/
API References:
https://api.highcharts.com/highcharts/yAxis.labels.formatter
https://api.highcharts.com/highcharts/data.seriesMapping
You meant to positioning the label, you can use yAxis.labels.y to position offset of all labels relative to the tick positions on the axis.

Highcharts - Performance issue using chart with x values date and TIME

I am plotting a chart with ‘y’ axis being numeric values and ‘x’ axis being date time values.
I was able to process a JSON object of 3000 items. However, because of our business rules, we also need to display the time: hours + minutes in the chart’s tooltips.
This changed everything!
Now the chart takes about 15 seconds to plot 2000 records. This is unacceptable.
I can see clearly that when I remove the time part of my Date object the charts works perfectly. It is just when added the hours and minutes that performance gets affected.
Trying different things I realized that your charts should support the amount of data I am using since it is not massive.
We love the charts but performance is key for us to continue using your products.
Can you help me with this issue?
Please check this fiddle so you can understand my problem. Feel free to remove the hours and minutes variables from the DateUtc creation:
https://jsfiddle.net/17a3jry9/7/
Thanks in advance!

Highcharts : selection

I made a barchart with dates. Currently, to remove the dates, you must click on the dates in the legend. I wish delete multiple dates at once.
Let's take an example. My dates range from 1960 to 2015. If I would have on my chart the dates from 2000 to 2005, so I would like that if you click on 1960 and 1999, then all the dates between are deleted / hidden. It goes faster when many dates.
How to do ?
Here is my code :
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},

'#7cb5ec',
'#434348',

Thanks
Rather than having each year as its own series, I would recommend that you place the years as the values in your x-axis (as categories) and then use Highcharts' native zoom function to allow users to select a certain date range.
I've updated your fiddle with some changes, which I explain below: https://jsfiddle.net/brightmatrix/hr28s27L/
First, in your chart option, I added zoomType: 'x' to allow users to use their mouse to zoom in on specific years. The value x means they can only zoom horizontally (across), which makes for a "cleaner" interaction.
chart: {
type: 'column',
zoomType: 'x'
},
Second, I updated your x-axis with the years as the categories/values:
xAxis: {
categories: ['2004','2005','2006','2007','2008','2009','2010','2011','2012','2013','2014','2015','2016']
},
Lastly, I updated your series to show just the data points, which are then plotted on the y-axis:
series: [{
name: 'data by year',
data: [49.9,83.6,48.9,69.1,83.6,40.9,69.9,83,28.9,40.9,81.6,24.9,46.4]
}]
Here is what happens when a user clicks and drags their mouse cursor:
The shaded box is what they are selecting. Once they release the cursor, the chart will automatically adjust to show only what they chose. A "Reset Zoom" button will appear at the top right to allow them to go back to all years:
Update (July 19, 2016): I did some research on adding a simple slider element to this chart that allows users to choose from a range of years.
An updated version of my fiddle that shows this example chart with sliders can be found here: https://jsfiddle.net/brightmatrix/uvat8u05/.
The code to handle the sliders is shown below. I discovered that explicitly setting the slider values to integers using the parseInt() function solved a couple of problems:
You can correctly compare the slider values to make sure users can't choose an end year that is earlier than the start year.
The setExtremes() function correctly shows a single year when users choose the same start and end year.
All x-axis labels are shown at all times. Before I added parseInt(), some labels disappeared when users chose different values in the sliders.
Please be sure to read the comments I've left in both the HTML and Javascript panes, as I've included additional details on why I made certain code decisions.
// on change handler for both sliders
$('.mySlider').bind('change', function(e) {
e.preventDefault();
var chart = $('#container').highcharts();
// convert the slider values to integers to make sure setExtremes() works as expected
var slider1Val = parseInt($('input[name="slider1"]').val());
var slider2Val = parseInt($('input[name="slider2"]').val());
if (slider2Val < slider1Val) {
// warn the user if they try to choose an end year that is later than the start year
alert("You can't choose an end year that is earlier than your start year.");
} else {
// use setExtremes to set the x-axis ranges based on the values in the sliders
chart.xAxis[0].setExtremes(slider1Val, slider2Val);
}
});
I hope this information is helpful for you.

Highcharts datagrouped updating column lose visible integrity

In a project, I'm using something very similar to this fiddle: http://jsfiddle.net/Z3vhg/
The code for this dynamically updating data-grouped columns chart is the following:
$('#container').highcharts('StockChart', {
chart : {
type: 'column',
events : {
load : function() {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function() {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series.addPoint([x, y], true, true);
}, 1000);
}
}
},
yAxis: {
offset: 30
},
rangeSelector: {
buttons: [{
count: 1,
type: 'minute',
text: '1M'
}, {
count: 5,
type: 'minute',
text: '5M'
}, {
type: 'all',
text: 'All'
}],
inputEnabled: false,
selected: 2
},
title : {
text : 'Live random data'
},
exporting: {
enabled: false
},
series : [{
name : 'Random data',
dataGrouping: {
groupPixelWidth: 60
},
data : (function() {
// generate an array of random data
var data = [], time = (new Date()).getTime(), i;
for( i = -999; i <= 0; i++) {
data.push([
time + i * 1000,
Math.round(Math.random() * 100)
]);
}
return data;
})()
}]
});
The problem can be observed in the fiddle above: as the data updates and adds new points, the first point on the x axis is shifted, but since data grouping is used, the column remains there but gives the impression that the first column value is actually changing...
Any help appreciated, as it may be a weird combination issue.

Highstock Issue - Can't draw and plot chart correctly

I'm working on project to display stock information using Highstock.
Question 1:
I tried to display ohlc data using ohlc graph, high and low using areasplinerange graph, and volume using column chart.
Everything works fine, if i zoom 1m, 3m, 6m, YTD, and 1y. Here is the snapshot. link1. But if zoom to All, The graph messed up like this link2.
Am i wrong in my coding or it's bug?
Question 2:
In the same chart, I have code to change the type of graph from ohlc to line. It works fine when I zoom to 1m, 3m. Here is the snapshot link3. But it show me no line chart when i zoom to 6m, 1y, and All. Here is the snapshot link4.
How can this happen?
Thank you for your help.
The Code:
Here is the code that i used to display the chart
$.getJSON(url, function (data1) {
$.getJSON(urlprediction, function (data2) {
var ohlc = [],
volume = [],
closed = [],
forecast = [],
dataLength1 = data1.length;
dataLength2 = data2.length;
for (i = 0; i < dataLength1; i++) {
ohlc.push([
data1[i][0], // the date
data1[i][1], // open
data1[i][2], // high
data1[i][3], // low
data1[i][4] // close
]);
closed.push([
data1[i][0], // the date
data1[i][4] // close
]);
volume.push([
data1[i][0], // the date
data1[i][5] // the volume
])
}
for (i = 0; i < dataLength2; i++) {
forecast.push([
data1[i][0], // the date
data1[i][1],
data1[i][2], // close
])
}
// set the allowed units for data grouping
