series: [{
type: 'flags',
name: 'Flags on axis',
data: [{
x: Date.UTC(2011, 2, 1),

$("#btnAddFlag").click(function () {
chart.series[0].setData(
{
x: Date.UTC(2011, 2, 1),

});
});
Above code is part of highstock chart option and I want to add flag based on user event click. However I able to add the new point flag into the chart but the existing flags which title A and C will be missed out.
how can I add the new flag into the chart with the existing flags ?
On the other hand, I am able get the flag data but I'm unsure to
generate the correct data structure and reinitialize the old and new
flag data back into the chart.
Thank you.
Use addPoint instead of setData.
http://api.highcharts.com/highstock#Series.addPoint()
$("#btnAddFlag").click(function () {
chart.series[0].addPoint({
x: Date.UTC(2011, 2, 1),
title: 'B'
});
});

I am using the config below to show the tooltips:
tooltip: {
pointFormat: '{point.y}'
},
the data is like:
data: Array(4)
0: {name: "RF_test_93219167", y: 1274958}
1: {name: "RF_test_26400097", y: 1274958}
2: {name: "RF_test_50328208", y: 1274958}
3: {name: "RF_test_73758432", y: 1274958}
and the tooltips still shows the Brand key in front of the value. and I don't want it to be bold or formatted, just show 1274958. just want it simple, and I don't want a dot in front of the value either. how can I achieve it?
tooltip: {
formatter: function () {
return this.point.name + ':' +this.y;
}
},
use this instead of pointFormat to achieve the same, you also add additional things needed on the tooltip using this method.
I'm doing a combo scatter and line charts (it's a electoral poll tracker) following this example from HC docs:
series: [{
type: 'scatter',
name: 'Party1',
data: [10.1,9.2,9.8]
}, {
type: 'scatter',
name: 'Party2',
data: [6.5,6.5,6.8]
}, {
type: 'spline',
name: 'Party1-tracker',
data: [10.1,9.8,10.0]
}, {
type: 'spline',
name: 'Party2-tracker',
data: [6.5,6.5,6.6]
}]
On another document, I can make a chart from a Google Spreadsheet. I've followed this Jack Dougherty example: https://jackdougherty.github.io/highcharts-with-google-sheets/bubble.html
data: {
// insert the key from your public Google Sheet
googleSpreadsheetKey: '1fYJOd-2agLPg38qhblS8qoZGWGkKcK-3uTsMpf37Hys',
// insert Google Sheet column headers (x, y, z...) to match column numbers (0, 1, 2...)
seriesMapping: [{x: 0, y: 1, z: 2, name: 3, country: 4, category: 5}],
complete: function(data) {
categoriesIntoSeries(data);
changeSeriesColors(data);
}
},
plus
/**
* Here, all data is split into categories depending on the 'category' property
* Needed for correct legend display
*/
function categoriesIntoSeries(data) {
rows = data.series[0].data;
data.series = [];
for (i = 0; i < rows.length; i++) {
cat = rows[i].category;
catExists = false;
for (j = 0; j < data.series.length; j++) {
if (data.series[j].name == cat) {
// Add a data point to existing series
data.series[j].data.push(rows[i]);
catExists = true;
}
}
if (!catExists) {
// When category is encountered for the first time, create a series
data.series.push({name: cat, data: [rows[i]]})
}
}
}
What I've tried unsuccessfully is (maybe it's impossible) to connect each column from my spreadsheet to each 'series' element. Something like this:
{
type: 'scatter',
name: 'Party1',
data: /*get data from spreadsheet column 1 or a json field*/
}
I'll be thankful if you can tell us if it's possible and, if yes, point me to some documentation or example on how to do this
You can use seriesMapping array for this. It should contain a mapping for every column from the sheet.
Refer to this live demo: http://jsfiddle.net/kkulig/b45s1Luh/
seriesMapping: [{
x: 0,
y: 1 // first column series
}, {
x: 0,
y: 2 // second column series
}, {
x: 0,
y: 3 // third column series
}]
}
API reference: https://api.highcharts.com/highcharts/data.seriesMapping
Elaborating a graph where I point with y different, and 'x' equals; I put in the series:
series: [{
name: 'Grafico 1',
data: data,
dataLabels: {
enabled: true,
formatter: function () {
return Highcharts.numberFormat(this.y, 2)
},
color: "#000000"
},
stacking: 'normal',
}]
and as a result in the chart have the highest value added with the smaller one, that is:
http://i.imgur.com/Ups7AzT.png
If I remove the statement "stacking: 'normal'", I instead the chart without the line joining the points:
http://i.imgur.com/gMAO5VW.png
I ask: you can have the chart without the value added is greater than the lower (ie the value 18 is represented as 18 in the chart, and 26.45 because the child is 8.45)?
I have an array of objects that I want to display in highcharts. Every object has a name and a value.
I have tried to get this to work by doing
var objects = objectArray[]; // objectArray being an array of the objects I want data on
var objectNames = nameArray[]; // This being an array of all the names of the objects
var objectValues = valueArray[]; // An array of all the values of the objects
series: [{
data: objects.value,
name: objects.name
}]
This blew up on me. So I tried building the series like this:
series: [{
data: objectValues,
name: objectNames
}]
This gave me data for the values, but the name was all of the names in the objectNames array... for every single piece of data. so I tried using
series: [{
data: objectValues
},
{
data: objectNames
}]
This resulted in seeing the chart for the objectValues, and in the legend, another option for the names - which is completely unacceptable because there's no point in having a series of labels, right?
So I decided I would programmatically build out a series, using a foreach loop and then pass that into the constructor. However, http://www.highcharts.com/docs/getting-started/how-to-set-options/ says this is "bad code".
What I'm wanting is to be able to pass an array of objects to highcharts, tell it that every piece of data's 'name' is going to be the name value on that particular object, and the data is going to be tied to that particular object's value field. Is there a way to do this? Or is the only option what highcharts considers 'bad'?
So I found a solution.
After getting the data, I did
$.each(item, function (index, value) {
objects.push([value.name, value.value]);
});
And then bound my series with
series: [{
data: objects,
name: 'Value Type Description'
}]
So I have "Value Type Description" in the legend, but when I hover over a specific point I have the name as the label, and valid data displaying in graph form.
I found at http://api.highcharts.com/highcharts#series that if you have an array of two dimensional arrays, you can just pass a string as the first parameter and it would parse it as the label for that point.
EDIT: Example per request.
So you have two pieces to the series field, data and name. Name does NOT apply to the data, that will be the name of the axis.
So data is an array of key/value pairs.
data: [
{[key1, value1]},
{[key2, value2]},
{[key3, value3]}
]
And name is what the "main" label will be - "My Data Stuff" for example.
Then, when you load the chart, in the legend it should say "My Data Stuff", but when you hover over a specific point, say the first one, it will display the Key1 Value1 information.
data: [{
name: 'Point 1',
y: 1,
test1:9,
test2:'ddaf'
}, { -------> right
name: 'Point 2',
y: 5,
test1:12,
test2:'ddddaf'
}]
data: [{
my_name: 'Point 1',
y: 1,
test1:9,
test2:'ddaf'
}, { -------> we change 'name' to 'my_name',
my_name: 'Point 2', then the name you want to show become
y: 5, 'Slice', instead of 'Point 1','Point 2'
test1:12,
test2:'ddddaf'
}]
data: [{
my_name: 'Point 1',
my_y: 1,
test1:9,
test2:'ddaf'
}, { -------> Now,we get nothing.
my_name: 'Point 2',
my_y: 5,
test1:12,
test2:'ddddaf'
}]
So,the 'name' and 'y' is the key.
How can we get next elements name in Highcharts
for example
series: [{ name: 'weight', data: [50, 48, 80, 70]},
{ name: 'height',data: [5.8, 5.1, 6.1, 6.0]}
]
tooltip: {
formatter: function(){
return this.series.name;//i want to return here next elements name also is there any way
}
}
in the above tooltip iam returning only current element name, is there any way to get immediate next elements name there..?
You can always use shared tooltip, take a look: http://api.highcharts.com/highcharts#tooltip.shared
