How can I show only one x-axis in synchronous chart highchart

$('#container').bind('mousemove touchmove touchstart', function (e) {
var chart,
point,
i,
event;
for (i = 0; i < Highcharts.charts.length; i = i + 1) {
chart = Highcharts.charts[i];
event = chart.pointer.normalize(e.originalEvent);
point = chart.series[0].searchPoint(event, true);
if (point) {
point.highlight(e);
}
}
});
Highcharts.Pointer.prototype.reset = function () {
return undefined;
};
Highcharts.Point.prototype.highlight = function (event) {
event = this.series.chart.pointer.normalize(event);
this.onMouseOver(); // Show the hover marker
this.series.chart.tooltip.refresh(this); // Show the tooltip
this.series.chart.xAxis[0].drawCrosshair(event, this); // Show the crosshair
};
function syncExtremes(e) {
var thisChart = this.chart;
if (e.trigger !== 'syncExtremes') { // Prevent feedback loop
Highcharts.each(Highcharts.charts, function (chart) {
if (chart !== thisChart) {
if (chart.xAxis[0].setExtremes) { // It is null while updating
chart.xAxis[0].setExtremes(
e.min,
e.max,
undefined,
false,
{ trigger: 'syncExtremes' }
);
}
}
});
}
}
// Get the data. The contents of the data file can be viewed at
$.getJSON(
'https://cdn.rawgit.com/highcharts/highcharts/v6.0.4/samples/data/activity.json',
function (activity) {
$.each(activity.datasets, function (i, dataset) {
// Add X values
dataset.data = Highcharts.map(dataset.data, function (val, j) {
return [activity.xData[j], val];
});
$('<div class="chart">')
.appendTo('#container')
.highcharts({
chart: {
marginLeft: 40, // Keep all charts left aligned

valueSuffix: ' ' + dataset.unit
}
}]
});
});
}
);
Any help will be appreciated

You can hide unwanted x axes using visible property:
xAxis: {
visible: i === 2,
(...)
},

Highchart: is it possible to change the font of the label in Highchart via a click of a button?

Link to JFiddle: http://jsfiddle.net/z24ysp8m/3/
Here is the code in concern:
$(function() {
var chartData = [-5, 5, -10, -20];
var timeStamps = [];
var index = 1;
var pWidth = 25;
$('#b').click(function(){
timeStamps.push(new Date());
var buttonB = document.getElementById('b');
buttonB.disabled = true;
/* if(index == 1){
$('#container').highcharts().xAxis[0].labels.style = {"color":"#6D869F","fontWeight":"bold"};
}*/
if(index <= chartData.length){
$('#container').highcharts().series[0].remove();
$('#container').highcharts().addSeries({pointPlacement: 'on', data: [chartData[index - 1]],
pointWidth: pWidth});
$('#container').highcharts().xAxis[0].setCategories([index]);
setTimeout(function(){index++;}, 2000);
}
if(index < chartData.length){
setTimeout(function(){buttonB.disabled = false;}, 1500);
}else{
setTimeout(function(){buttonB.style.visibility="hidden";}, 1500);
}
if(index == chartData.length - 1){
setTimeout(function(){document.getElementById('b').innerHTML = 'Lasst Period';}, 1500);
}
console.log(timeStamps);
})
// $(document).ready(function () {
Highcharts.setOptions({
lang: {
decimalPoint: ','
},
});
$('#container').highcharts({
chart: {
type: 'column',
width: 170,
marginLeft: 74,
marginRight: 16,
marginBottom: 60
},
title: {
text: ''
},
colors: [
'#0000ff',
],
xAxis: {
title: {
text: ''
// offset: 23
},
gridLineWidth: 1,
startOnTick: true,
tickPixelInterval: 80,
categories: ['Filler'], // used only to make sure that the x-axis of the two charts
// are aligned, not shown on the chart via setting the font color to white
min:0,
max:0,
labels: {
style: {
color: 'white'
}
}
},
yAxis: {
title: {
text: 'Value'
},
min: -20,
max: 20,
tickPixelInterval: 40
},
plotOptions: {
series: {
animation: {
duration: 1000
}
}
},
credits: {
enabled: false
},
tooltip: {
formatter: function () {
return Highcharts.numberFormat(this.y, 2) + '%';
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
data: [],
pointWidth: pWidth
}]
});
// });
});
I want that the x-axis has no label when the page is loaded (The reason why I added in a filler text with white font is due to the fact that I don't want the size of the chart change upon click of a button). And upon the click of button, the label should be consecutively 1, 2, 3, 4...
Is there anyway around it except for setting marginBottom (which is not very precise)?

You may use .css() method for changing fill color of your text label.
Here you can find information about this method:
http://api.highcharts.com/highcharts#Element.css
Highcharts.each($('#container').highcharts().xAxis[0].labelGroup.element.children, function(p, i) {
$(p).css({
fill: 'red'
});
});
And here you can find simple example how it can work:

Highcharts bar chart wont animate

Not sure why because I have done it in the past, but I have a Highcharts bar chart and it won't animate. This is the declaration of the chart,
function initializeData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push({
name: setName($scope.jsondata[x].name),
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 5000);
}
function updateData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
console.debug("here");
for (x = 0; x < 5; x++) {
$scope.chart.series[0].data[x].update({
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'category',
labels: {
style: {
fontSize: '11px'
}
}
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Total Score',
align: 'high'
}
},
legend: {
enabled: false
},
tooltip: {
pointFormat: 'Total Score <b>{point.y:.3f}</b>'
},
series: [{
name: 'Active Users',
data: [],
dataLabels: {
enabled: true,
rotation: 30,
style: {
fontSize: '10px',
fontFamily: 'Verdana, sans-serif'
},
format: '{point.y:.3f}', // one decimal
}
}]
});
And as you can see I have animate : true, so I am not sure what is the problem here. I have this older plunker where all of the data is in separate series, but it animates fine. But this is the plunker I am working on and having trouble with. They are like identical basically. In the newer one I broke out the initialization of data into its own method, but that is the only real main difference.
Some edits:
So as I was saying, I have done things this way with an areaspline chart (I know it was said they work a bit different but they are set up identically).
function initializeData() {
$interval.cancel(mainInterval);
$scope.previousPackets = '';
$http.get("https://api.myjson.com/bins/nodx").success(function(returnedData) {
var newdata = [];
var x = (new Date()).getTime();
for (var step = 9; step >= 0; step--) {
newdata.push([x - 1000 * step, 0]);
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 2000);
}
function updateData() {
$http.get(url + acronym + '/latest').success(function(returnedData) {
var x = (new Date()).getTime();
if ($scope.previousPackets != returnedData[0].numPackets) {
$scope.chart.series[0].addPoint([x, returnedData[0].numPackets], true, true);
$scope.previousPackets = returnedData[0].numPackets;
} else {
$scope.chart.series[0].addPoint([x, 0], true, true);
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'areaspline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Packets'
},
plotLines: [{
value: 0,
width: 1,
color: '#d9534f'
}]
},
tooltip: {
formatter: function() {
return Highcharts.numberFormat(this.y) + ' packets<b> | </b>' + Highcharts.dateFormat('%H:%M:%S', this.x);
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Packets',
data: []
}]
});
I also updated the first chunk of code with the initializeData() method and updateData() method which are seemingly identical in both different charts.

It looks like it plays an important role if you provide your data at chart initialization or after. For simplicity I refactored your code a little
function initializeChart(initialData, onload) {
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: onload
}
....
series: [{
name: 'Active Users',
data: initialData,
dataLabels: {
enabled: true,
format: '{point.y:.3f}', // one decimal
}
}]
});
}
function getData(callback) {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push([setName(ret[x].name), ret[x].data]);
}
callback(newdata);
});
}
As a result your two planks are in essense reduced to two methods below. The first initializes chart with preloaded data and the second updates data in existing chart.
function readDataFirst() {
getData(function(newdata) {
initializeChart(newdata);
});
}
function initializeChartFirst() {
initializeChart([], function() {
getData(function(newdata) {
$scope.chart.series[0].setData(newdata);
})
});
}
The first one animates fine while the second does not. It looks like highcharts skips animation if dataset is not initial and is treated incompatible.
However if you really want to have animation in your current plant (chart first workflow) you can achieve that by initializing first serie with zeros and then with the real data. This case it will be treated as update
function forceAnimationByDoubleInitialization() {
getData(function(newdata) {
initializeChart([]);
var zerodata = newdata.map(function(item) {
return [item[0], 0]
});
$scope.chart.series[0].setData(zerodata);
$scope.chart.series[0].setData(newdata);
});
All these options are available at http://plnkr.co/edit/pZhBJoV7PmjDNRNOj2Uc

Add start-date and end-date as a Xaxis label in highchart

I use date as a string in my chart.
How can I use my start-date and end-date string variables as a label in my xAxis?
start-date = '10.02.2013'
end-date = '10.05.2013'
The code and the chart image is attached. The only thing I need to do is to add startDateLabel and endDateLabel.
var dateEndLabel, dateStartLabel, i, j, lastDate, seriesData, x, y;
i = 0;
seriesData = new Array();
lastDate = data[i].Values.length - 1;
dateStartLabel = data[i].Values[0].Time;
dateEndLabel = data[i].Values[lastDate].Time;
while (i < data.length) {
seriesData[i] = [];
j = 0;
x = [];
y = [];
while (j < data[i].Values.length) {
x = data[i].Values[j].Time;
y = data[i].Values[j].Value;
seriesData[i].push([x, y]);
j++;
}
i++;
}
return $("#criticalWPtrend").highcharts({

});

Yes, this is possible with the renderer method. See this basic example.
chart.renderer.text('10.02.2013', 0, 300)
.attr({
rotation: 0
})
.css({
color: '#4572A7',
fontSize: '16px'
})
.add();
You are going to need to pay attention to the x/y locations (the 2 other params) to place it correctly. You can also modify the text styling.

I'm not sure, but i think you just need to update your xAxis by update method
this.xAxis[0].update({
title: {
text: "start-date = '10.02.2013' end-date = '10.05.2013'",
style: {
fontSize: '10px'
}
}
});
Here's example: http://jsfiddle.net/FEwKX/
But!
If your mean that the start and end dates need to tie to edges, you must specify xAxis settings in config
xAxis: {
categories: categoriesArray
}
where categoriesArray is array like this:
['10.02.2013', '', '', '', '', '', '', '', '', '', '', '10.05.2013']
It should be the same lenght as your lenght of series data.
Check out here: http://jsfiddle.net/FEwKX/1/
Hope that'll help you.

You can also use labelFormatter and http://api.highcharts.com/highcharts#xAxis.labels.formatter and check if labels isFirst or isLast then use your dates, in other cases return proper value (like number).

Highcharts + Highslide: When opening a new highslide popup or clicking anywhere else, close any previously opened popups

So, I discovered that when you have are utilizing highslides in conjuction with highcharts data, its possible to keep clicking new datapoints and have an endless number of modal windows pop up. I wanted to build something that will close an existing highslide popup window if you open a new highslide or if you click anywhere else, either on the screen or on a filter.
I wrote this little function and added it to my beginning statement but it did not work.
<body onclick="javascript:parent.window.hs.close();">

The question is, can someone show me an example where I can accomplish my above described behavior?
