I need to use Highmaps to display on a map some information such as points, lines...
Displaying the initial map and some mappoint (with latitude/longitude coordinates) works well.
But when I add a simple mapline (linestring) between 2 points already displayed on the map, the mapline is not drawn.
Here is an example : https://jsfiddle.net/vegaelce/4L928trp/
The 2 mappoints are correctly placed on the map with the following data :
data: [{
name: 'Paris',
geometry: {
type: 'Point',
coordinates: [2.34,48.86]
}
}, {
name: 'Orly',
geometry: {
type: 'Point',
coordinates: [2.40,48.75]
}
}]
But the mapline (named "road") added to link the 2 points is not displayed with the following data :
data: [{
geometry: {
type: 'LineString',
coordinates: [
[2.34,48.86], // Paris
[2.40,48.75] // Orly
]
}
}],
Do I need to add something else ?
If you use the TopoJSON maps, what you are trying to do works. https://jsfiddle.net/blaird/y1Ld6bgs/1/
(async () => {
const topology = await fetch(
'https://code.highcharts.com/mapdata/countries/fr/fr-idf-all.topo.json'
).then(response => response.json());
// Prepare demo data. The data is joined to map using value of 'hc-key'
// property by default. See API docs for 'joinBy' for more info on linking
// data and map.
var data = [
["fr-idf-se", 69699],
["fr-idf-hd", 14200],
["fr-idf-ss", 17301],
["fr-idf-vo", 14350],
["fr-idf-vm", 29728],
["fr-idf-vp", 28610],
["fr-idf-yv", 21667],
["fr-idf-es", 16494]
];
// Create the chart
Highcharts.mapChart('container', {
chart: {
map: topology
},
title: {
text: 'Highcharts Maps basic demo'
},
subtitle: {
text: 'Source map: Île-de-France'
},
series: [{
mapData: Highcharts.maps["countries/fr/fr-idf-all"],

borderColor: "#ffffff",
joinBy: ["hc-key", "CODE_REGION"],
keys: ["CODE_REGION", "value"]
}, {
type: 'mapline',
data: [{
geometry: {
type: 'LineString',
coordinates: [
[2.34, 48.86], // Paris
[2.40, 48.75] // Orly
]
}
}],
showInLegend: true,
lineWidth: 2,
name: "Road",
nullColor: '#f00',
color: '#f00',
enableMouseTracking: false
}, {
type: 'mappoint',
color: '#333',
name: "Towns",
showInLegend: true,
data: [{
name: 'Paris',
geometry: {
type: 'Point',
coordinates: [2.34, 48.86]
}
}, {
name: 'Orly',
geometry: {
type: 'Point',
coordinates: [2.40, 48.75]
}
}],
enableMouseTracking: false
}]
});
})();
In the Adding Points and Lines doc: https://www.highcharts.com/docs/maps/adding-points-and-lines
Prior to v10, the coordinate system used in most of our maps was a
custom one, where both the X and Y values ranged from 0 to some
thousands. This still applies when loading GeoJSON maps rather than
TopoJSON maps from the Map Collection. With the support of the proj4js
library, points could be placed by the lon and lat options. Without
proj4.js, points were added as x, y pairs on the same coordinate
system as the map. Maplines however were given as paths.
It explains that if you don't use the Topo data, you'll have to either convert the coordinates, or use the same coordinate system as the map for lines.
P.S. Not sure why setting color of the line doesn't work, but setting nullColor does. But, that is what I had to do to make the line red
After digging into I think that it is a bug and I reported it on the Highcharts Github issue channel where you can follow this thread: https://github.com/highcharts/highcharts/issues/17086
I'm trying to populate a map of the U.S. in HighMaps with data from an html table. The map is showing but the data point is not. It's a latitude/longitude point. The documentation is sparse, so I'm not sure what I'm doing wrong. Here's a JSFiddle: https://jsfiddle.net/sfjeld/1wjm04fc/6/
Highcharts.mapChart('container', {
chart: {
map: 'countries/us/custom/us-all-territories'
},
series: [{
name: 'Basemap',
dataLabels: {
enabled: true,
format: '{point.name}'
}
},
{
// Specify points using lat/lon
type: 'mappoint',
data: {
table: 'pvsoiling-table',
startRow: 1,
startColumn: 1,
endColumn: 2
},
name: 'PV',
marker: {
fillColor: 'white',
lineColor: 'black',
lineWidth: 2,
radius: 10
},
color: Highcharts.getOptions().colors[1]
}
]
});
thanks,

You can make the following changes to your code:
At the start of your <script> section, load your HTML table data into a JavaScript array:
var mapData = [];
Highcharts.data({
table: document.getElementById('pvsoiling-table'),
startColumn: 1,
endColumn: 2,
firstRowAsNames: true,
complete: function (options) {
options.series[0].data.forEach(function (p) {
mapData.push({
lat: p[0],
lon: p[1]
});
});
//console.log(mapData);
}
});
We will refer to this mapData array later on. Here is what it contains:
[
{ "lat": 33.3, "lon": -111.67 }
]
Make changes to the series section in your Highcharts.mapChart.
series: [{
name: 'Basemap',
nullColor: '#e0f9e3',
dataLabels: {
enabled: true,
format: '{point.name}'
}},
{
// Specify points using lat/lon
data: mapData,
type: 'mappoint',
name: 'PV',
marker: {
fillColor: 'white',
lineColor: 'black',
lineWidth: 1,
radius: 3
},
color: Highcharts.getOptions().colors[1]
}
]
The key part to note is the data: mapData option. The JavaScript mapData variable is the exact array that we need to represent a set of points on the map. In our case the array only contains one point - but that's because there is only one relevant row of data in the HTML table.
My map ends up looking like this:
It looks like the marker is in or near Phoenix, AZ.
Final notes:
(a) I also adjusted the marker to have lineWidth: 1 and radius: 3 (a bit smaller).
(b) I added a document ready function around everything, to ensure the DataTable is loaded before you try to read its data.
(c) There may be a more elegant way to do this, but I followed the approach in this demo. The demo actually shows how to join 2 different sets of data - not what you need. But it does show a good approach for extracting the HTML data so it can be used in the map.
Using the the Highcharts.data({...}) approach lets you access any HTML table. But since you are using DataTables, you can choose to do the following, instead. It uses the DataTables API to access each row of data:
var mapData = [];
$('#pvsoiling-table').DataTable({
"initComplete": function(settings, json) {
var api = this.api();
api.rows().data().each(function (p) {
mapData.push({ lat: Number(p[1]), lon: Number(p[2]) });
});
// your Highcharts.mapChart() logic, in a function:
buildChart();
}
});
The highcharts chart is not showing.
hc.xAxis[0].categories are loaded ok, but hc.series are not
r.forEach(x => {
var hc = Highcharts.chart('chart_div', {
xAxis: { categories: x.categories },
series: x.series,
});
console.log(hc.series); // 1st
console.log(x.series); // 2nd
});
The 1stconsole.log shows no data and the 2nd one shows this:
[{name: 'DE Shaw Comp (75;Q)', data: [100,100.5,101.91,103.03,104.37,103.85,103.22,104.77,105.71,105.5,107.08,107.51,106.33,107.18,107.18,108.68,109.44,110.87,110.53,111.75,115.21,116.83,117.41,116.82,116.24,118.21,119.99,121.79,121.54,122.88,122.27,123.86,124.6,126.22,128.36,124.77,129.14,], color: '#33a', label:{enabled:false}},{name: 'SPX', data: [100,94.93,94.53,100.77,101.05,102.59,102.69,106.34,106.21,106.08,104.02,107.58,109.54,111.49,115.64,115.6,116.65,118,118.57,120.86,120.93,123.26,125.99,129.53,130.81,138.16,132.77,129.2,129.56,132.36,133,137.79,141.96,142.57,132.67,135.04,122.65,119.76], color: '#a33', label:{enabled:false}},{name: 'HFRI RV: MULTI-STRATEGY', data: [100,98.37,97.83,99.53,101.19,102,102.66,103.99,104.87,105.72,106.02,106.54,107.66,109.08,109.73,110.07,110.37,110.38,110.58,111.34,111.51,111.95,112.37,112.46,113.29,114.53,114.13,113.48,114.48,115.17,114.97,116.2,116.26,116.68,115.32,114.95,,], color: '#aa3', label:{enabled:false}}]
which looks like a proper input.
series: eval(x.series) is the solution
without eval x.series was interpreted as a string, not as an array of Object as I thought
I am trying to write a script that produces a col chart. The data is from an MySQL query that produces the following array content:
97.2,63.9,33.4,28.9,325.2,114.9,46.1,56.7,104.9,4.5,42.2,56.4,10.5
When I run the script I get an error:
SyntaxError: missing ] after element list
I have tracked down to where I thik the error is but can not see whats wrong.
Inside the jQuery function I have an PHP echo statement which populates the $data variable with the data, $data[] = $row_An['AValue'];.
The values are correct as seen in FireFox dev console. Can anyone see why I am getting the error.
$(function () {
<?php
$data[] = $row_An['AValue'];
?>
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'AN'
},
xAxis: {
categories: ['Inbound', 'Outbound', 'InService']
},
yAxis: {
title: {
text: ''
}
},
series: [{
data: [97.2,63.9,33.4,28.9,325.2,114.9,46.1,56.7,104.9,4.5,42.2,56.4,10.5],
pointStart: 0,
pointInterval
}]
});
});
Many thanks in advance
what's value in pointInterval ? its wrong to leave that without any value
series: [{
data: [97.2,63.9,33.4,28.9,325.2,114.9,46.1,56.7,104.9,4.5,42.2,56.4,10.5],
pointStart: 0,
pointInterval //here is error you should provide value or remove it
}]
Also, these two properties PointInterval and PointStart are part of plotOptions.series
your number of categories don't match with number of data points ,correct them
categories: ['Inbound', 'Outbound', 'InService']
I am in the process of moving from a built in graph library to HighStock.
I have to comply to crasy implementations. So at the end I got this configuration :
$(function() {
chart = new Highcharts.StockChart({
chart : {
renderTo : 'div_#divid#'
},
rangeSelector : {
selected : 0,
buttons: [{
type: 'day',
count: 7,
text: '7j'
}, {
type: 'day',
count: 15,
text: '15j'
}, {
type: 'day',
count: 30,
text: '30j'
}, {
type: 'all',
text: 'Tous'
}]
},
series : [{
type : 'column',
name : 'valeur',
data : data,
tooltip: {
valueDecimals: 2
}
}]
});
});
Here is the fiddled version.
I don't get whats wrong with my data. (but I think I did correctly the conversion for the dates.)

Thanks for your help.
I'm not sure, the problem is that you can't see the chart? That's cause your data contains '
Check the jsFiddle: http://jsfiddle.net/SqZY2/1/
You have this:
data = '[[1362355200000,672],[1362441600000,9764],[1367103600000,0],[1367190000000,0],[1367276400000,0],[1367362800000,0],[1367449200000,5490]]';
Must be this:
data = [[1362355200000,672],[1362441600000,9764],[1362528000000,9839],[1362614400000,9906],[1367103600000,0],[1367190000000,0],[1367276400000,0],[1367362800000,0],[1367449200000,5490]];
