OK. Rephrasing an unanswered earlier question.
I have a chart as shown below with the data loading dynamically through ajax.
A simplified version (without ajax) of this graph works fine as shown in this jsfiddle.
The code below is the chart as I use it, straight from its context.
The idea is there are several timeseries (x-axis) in the graph and I wish to display the wind characteristics of speed and direction at those same times through windbarbs. The windbarbs take two arguments at each defined x-value all other series take one argument (the y-axis).
My question is: why doesn't it work (why the stackdump) while it does work in jsfiddle (without the ajax call and thus without the addSeries call?
As a derivative: in the jsfiddle the onSeries attribute does not work. What is wrong there?
And finally: is it possible to get the windbarbs above the series graphs and not fixed on the x-axis?
The problem seems to be in the loading of the wind data after the loading of the other series. As that part is in the ajax call with the (idx == 'wind') condition it is quite easy to spot. It breaks in the setData call of highStock with the following stackdump:
Uncaught TypeError: r is undefined
setData highstock.src.js:33902
init highstock.src.js:33182
init highstock.src.js:54816
init windbarb.src.js:361

Without the wind data it works fine.
var doSensorIn10 = function(){
let ReferenceColours = ['#79bc6a', '#bbcf4c', '#eec20b', '#f29305', '#960018' ];
let ReferenceConcentrations10 = [0,25,50,90,180];
let t ={chart: { renderTo: 'chartcontainerIn10',type: 'spline',alignTicks: false, zoomType: 'xy', pinchType: 'xy'},

{ count: 12,type: 'hour',text: '12h'},

}
};
let chart = new Highcharts.StockChart(t);
chart.showLoading();
$.ajax({
url: 'airlinkdataIn10.json',
cache: false,
dataType: 'json',
success: function(resp){
let titles = {
'In_pm10': 'In_pm10','In_pm10_1hr': 'In_pm10_1hr','In_pm10_3hr': 'In_pm10_3hr','In_pm10_24hr': 'In_pm10_24hr','In_pm10_nowcast': 'In_pm10_nowcast','wind': 'wind'}
let idxs = ['In_pm10','In_pm10_1hr','In_pm10_3hr','In_pm10_24hr','In_pm10_nowcast','wind']
let cnt = 0;
idxs.forEach(function(idx) {
console.log('idx = ' + idx);
if (idx in resp) {
if (idx == 'wind') {
console.log('Doing Wind correctly : Before addSeries');
chart.addSeries({name: titles[idx], type: 'windbarb', showInLegend: false, onSeries: 'InPM2p5', tooltip: {valueSuffix: ' m/s'}, data: resp[idx] }, false);
console.log('Doing Wind correctly : After addSeries');
}
else {
console.log('Doing ' + idx + ' correctly');
chart.addSeries({name: titles[idx], data: resp[idx]}, false);
}
chart.series[cnt].options.zIndex = cnt+50;
}
cnt++;
});
chart.hideLoading();
chart.redraw();
}
}
)};
The data series (in short version) is as follows:
{"In_pm2p5":[[1609484460000,26.20], ... ]],
"In_pm2p5_1hr":[[1609484460000,32.90], ... ]],
...
"wind":[[1609484460000,0.0,194], ...]]}
Each parameter has 2880 values, wind may have one value less (which I tested in jsfiddle and does not seem to be a problem).
Thank you for your wide and clear description!
In this case it is hard to say why the chart is not rendering properly without reproduction of your data fetching. The addSeries feature should work without any issues with the windbarb type series.
Demo: https://jsfiddle.net/BlackLabel/ktLyunw8/
2.
in the jsfiddle the onSeries attribute does not work. What is wrong there?
I cannot see it, everything seems to work fine:
3.
And finally: is it possible to get the windbarbs above the series graphs and not fixed on the x-axis?
Like in the case of using the onSeries feature? Or render it totally above the plot area?
I'd like to render it above the plot area or in the top of the plot area (like without onSeries it is at the bottom) so all windbarbs in one line.
In this case, you can render the second xAxis and assign the winbarb series to it.

I am tried to get the series from the already displayed highchart and use that series to plot a new chart in another one html div, i have written below code to achieve this,finally i get the series from existing graph but can't render to the new html div
var data = chart.series; // series from already displyed
jQuery('#commonModal_res').highcharts({
chart: { zoomType: 'x'},
title: { text: "" },
subtitle: { text: 'Click and drag in the plotted area to zoom in' },
xAxis: { type: 'datetime' },
legend: { enabled: false },
series: data,
});
note : throwing too many recursion error
The problem occurs because you're trying to assign the complete and already built series object, instead of configuration object which is required. In order to make it work, you need to assign the configuration object by this way:
$('#new_con').highcharts({
chart: { zoomType: 'x'},
title: { text: "" },
subtitle: { text: 'Click and drag in the plotted area to zoom in' },
xAxis: { type: 'datetime' },
legend: { enabled: false },
series:charts[0].userOptions.series,
});
Then your chart should be rendered properly.
Additionaly, you can access appropriate chart by the Highcharts.charts array on global Highcharts object, where all charts are stored, just like that:
series: Highcharts.charts[0].userOptions.series,
In this case creating new charts array is unnecessary.

I have basic Waterfall chart (HighChart.js) basic Waterfall chart image example
How display two labels on each column? Besides, first label must be at top of column and another label must be on bottom of column. So it should be exactly like on image.
Now I have two ideas:
First label is rendered on first chart, second value will be rendered on additional hidden chart (link to example: [http://jsfiddle.net/gk14kh3q/1/][3])
$(function () {
$('#container').highcharts({
chart: {
type: 'waterfall'
},
title: {
text: 'Highcharts Waterfall'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'USD'
}
},
legend: {
enabled: false
},
series: [{
dataLabels: {
enabled: true,
// here need align label
}
}, {
dataLabels: {
enabled: true,
// here need align label
}
}]
});
});
Combine two label in one by using formatting function and useHTML property. And after that set position to labels by using css or external js
May be some others practices exist? I'll be very pleased for help. Even discussion can be usefull. Thank you!
P.S. How I could insert icons to chart like on provided image?
You can use chart.renderer.label for adding new dataLabels for your column points. You can also use chart.renderer.image for adding arrows to your chart:
var addLabels = function(chart) {
$('.custom').remove();
var series = chart.series[0],
url;
Highcharts.each(series.data, function(p, i) {
if (i) {
chart.renderer.label(p.secondLabel, p.plotX + chart.plotLeft, p.yBottom + chart.plotTop).attr({
'text-anchor': 'middle'
}).addClass('custom').add();
if (p.y > 0) {
url = 'https://upload.wikimedia.org/wikipedia/commons/thumb/d/d1/Arrow_up.svg/1000px-Arrow_up.svg.png';
} else {
url = 'https://upload.wikimedia.org/wikipedia/en/f/f1/Down_Arrow_Icon.png'
}
chart.renderer.image(url, p.plotX + chart.plotLeft, chart.plotTop + chart.plotHeight - 15, 8, 13).addClass('custom').add()
}
});
};
Here you can find an example how it can work:

I am loading Highcharts like this.
var options = {
credits: {
enabled: false
},
chart: {
renderTo: 'chart_box',
type: 'areaspline'
},
title: {
text: ''
},
xAxis: {
crosshairs: true,
labels: {
step: 5,
rotation: -45
}
},
series: []
};
Then I have a function which is called when graph needs to be loaded. Upon calling the function, data is fetched through AJAX and assigned to series and date lie this:
$.ajax({
url: 'url/charts',
type: 'post',
data: data
}).done(function(data) {
var dateCount = data.dates.length;
var stepCount = 1;
if (dateCount > 10) {
stepCount = 5;
}
options.xAxis.categories = data.dates;
$.each(data.series, function(name, elem) {
options.series.push({
name: name.replace('_', ' ').toUpperCase().trim(),
data: elem
})
});
chart = new Highcharts.Chart(options);
});
The issue here is that even though I have given step as 5 , it is showing dates with 15 dates interval. I mean in xAxis labels. It seems like it will be multiplied by three always. If I give 2, it will show 6 days interval in labels. Everything working fine in a chart which is not using AJAX to load data.
Highcharts has an example using irregular time intervals, I want to do the same on highstock howeverthere is no parameter for the xAxis-type.
JSFiddle code
My options are
$(function() {
$.getJSON('http://184.173.195.228/~ktwsn/temp2.php?action=get_sensor&sensor_serial%5B%5D=3B74F41400000069&sensor_serial%5B%5D=3BB2FA14000000E6&sensor_serial%5B%5D=3B91F11400000079&sensor_serial%5B%5D=3BC7F114000000E5&sensor_serial%5B%5D=3BC0F314000000E3&callback=?',
{action: "get_sensor"},
function(data) {
var seriesOptions = [];
$.each(data, function(key, val) {
seriesOptions.push({
name: val.name,
data: val.samples,
marker : {
enabled : true,
radius : 3
}
});
});
// create the chart
chart = new Highcharts.StockChart({
chart: {
renderTo: 'container',
},
xAxis: {
type: 'datetime'
},
rangeSelector: {
selected: 4
},
series: seriesOptions
});
});
});
Found it. The nomenclature between highcharts and highstock are different.
For Hightstock it's
xAxis: {
ordinal: false
}
The company really needs to combine highcharts and highstock. A single API documentation would be easier to follow.
I would verify that the output data is actually using the same time stamp.
Many cases like this include time stamps for the same date, but different times, which will always result in different x axis placement.
(I know that may be an obvious check, but I have seen it many times...)
I'm trying to put a second line on a Highchart using ajax with dynamic (periodic) updating. First line works fine using ajax. I think the problem is the format of the incoming data, but also how I'm splitting the data for each of the lines.
I have control of the format of the ajax data so it be could posted in most any form but it works for the first line.
Here is the ajax data that is received with each request:
[Date.parse("2013/02/14 14:29:00 -0000"), 51, 216510]
This will create a point for the first line at 51 but not anything for the second line which should be at 216510.
The following is the javascript I'm using:
var chart; // global
/**
* Request data from the server, add it to the graph and set a timeout to request again
*/
function requestData() {
$.ajax({
url: '/htbin/count_since_total',
success: function(point) {
var series = chart.series[0],
shift = series.data.length > 30; // shift if the series is longer than 300 (drop oldest point)
// add the point
chart.series[0].addPoint(eval(point), true, shift);
// call it again after one second
setTimeout(requestData, 1000);
},
cache: false
});
}
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
events: {
load: requestData
}
},
title: {
text: 'time'
},
xAxis: {
type: 'datetime'
},
yAxis: [{ // Primary yAxis
title: {text: 'count'},
opposite: false
}, { // Secondary yAxis
title: {text: 'Total'},
opposite: true
}],
series: [{
yAxis: 0,
name: 'number',
data: []
},{
yAxis: 1,
name: 'Total',
data: []
}],
});
});
EDIT 1:
Not working, no second line with suggested changes. I'm thinking that incoming data format is incorrect or it needs processing after receiving. Also how does the data get assigned to the proper line?
series: [{
yAxis: 0,
name: 'number',
data: []
},{
yAxis: 1,
name: 'Total',
data: []
}],
--------- end EDIT 1 ----------------
In your success-action/function, you are only updating series[0].
If you want to add a point to the second line, you'll have to add a point to series[1] as well.
Add a for loop to do the same for each serie.
success: function(point) {
for(var i = 0, length = chart.series.length; i < length; i++) {
var serie = chart.series[i],
// shift if the series is longer than 300 (drop oldest point)
var shift = serie.data.length > 30;
// add the point
serie.addPoint(eval(point), true, shift);
}
// call it again after one second
setTimeout(requestData, 1000);
}
