I have a working Highcharts bar chart with 2 series that exports to CSV correctly. I added a hidden ROUND series that should be included in the exported CSV data. Setting the includeInDataExport property to true is supposed make this happen. However, this is not working for me and I've not found an example showing how to correctly use this property.
Here are the current chart options.
{
chart: {
type: "bar"
marginTop: 30
spacingRight: 50
style: {
fontWeight: "400",
fontFamily: "Montserrat"
}
},
title: {
text: ""
}
xAxis: {
categories: Array(7),
lineWidth: 1
}
yAxis: {
min: 0,
lineWidth: 1
}
legend: {
reversed: true,
itemStyle: {
}
}
tooltip: {
headerFormat: "COMPANY: {point.x}<br/>",
pointFormat: "{series.name}: <b>${point.y}</b>"
}
plotOptions: {
bar: {
dataLabels: {
enabled: true
},
includeInDataExport: true
},
series: {
colorByPoint: true,
includeInDataExport: true
}
}
series: [
{
name: "ROUND",
data: [
0,
0,
0,
0,
0,
0,
0
],
visible: false,
showInLegend: false
},
{
name: "P2",
data: [
230.3,
228.25,
217.72,
243.34,
235.56,
205.73,
252.83
]
},
{
name: "P1",
data: [
115.15,
115.58,
104.2,
115.58,
113.34,
101.27,
121.3
]
}
]
}}
It seems that the current Highcharts logic doesn't allow to get CSV data from series which has visible set to false, see: https://github.com/highcharts/highcharts/blob/master/js/modules/export-data.src.js#L350
From this code, it seems like in the past someone has a purpose in it because of some bug, but I am not sure what to think about it now. If you want you can start a thread in the Highcharts Github issue channel: https://github.com/highcharts/highcharts/issues
As a workaround I suggest to use this logic just without this condition about series visibility:
Demo: https://jsfiddle.net/BlackLabel/n5za1q3x/
this.series.forEach(function(series) {
var keys = series.options.keys,
pointArrayMap = keys || series.pointArrayMap || ['y'],
valueCount = pointArrayMap.length,
xTaken = !series.requireSorting && {},
xAxisIndex = xAxes.indexOf(series.xAxis),
categoryAndDatetimeMap = getCategoryAndDateTimeMap(series, pointArrayMap),
mockSeries, j;
if (series.options.includeInDataExport !== false &&
!series.options.isInternal // #55
) {

Have a highstock chart with a large number of data around 60-80 thousand timestamp and sum. The problem is that none of the data which i give to highstock contains decimal but highstock shows some values that are decimals like 1.5 but my data does not have any 1.5. Does the highstock averages the data if timestamp is more than 1hour or anything? If it does averages the data than how to stop this averaging as i dont need decimal data

Highstock provides dataGrouping feature, which is enabled by default.
Please check the docs below and compare the result with:
disabled dataGrouping: http://jsfiddle.net/BlackLabel/tokz3aum/
enabled dataGrouping http://jsfiddle.net/BlackLabel/co16j85p/
You can disable dataGrouping or define your own approximation function which will round the result, for example:
series: [{
data: [...],
dataGrouping: {
approximation: function(arr) {
var len = arr.length,
ret = Highcharts.approximations.sum(arr);
if (Highcharts.isNumber(ret) && len) {
ret = ret / len;
}
return Math.round(ret);
}
}
}]

I want create a bar line graphs with navigator,range selector, y axis from both side and graph sector. I implement it using Highcharts.Chart() but it's x-axis not comes properly. when i create x-axis properly after change categories to ["2017-2-3'] then range selector goes to 1970 (default value) so i convert date to milliseconds. Now in the x-axis have unwanted values. I want to show only x-axis values which shows in category array. currently 1m,3m,6m not worked i think it happen because of this x-axis issue.

Just comment the tickInterval for the xAxis
//tickInterval : 2,
Fiddle
First of all, you have unsorted data. If you want to invert your data, use reversed option.
Also, the rangeSelector and the tickInterval are wrong. If you use datetime axis, then the basic unit is one millisecond.
However, to show dates only from the categories array, use the tickPositions option and formatter function for labels:
xAxis: {
reversed: true,
minRange: 1,
type: 'datetime',
tickPositions: categories,
labels: {
formatter: function() {
return Highcharts.dateFormat('%Y-%m', this.value);
}
}
},

API Reference:
https://api.highcharts.com/highcharts/xAxis.reversed
https://api.highcharts.com/highcharts/xAxis.tickPositions
https://api.highcharts.com/highcharts/xAxis.labels.formatter
(1) First always make sure that you are injecting timestamps in your categories, and formatting them in :
(1-1) xAxis.labels.formatter function [for x axis labels]
(1-2) navigator.xAxis.labels.formatter function [for navigation labels format)
(2) Second make sure that you are clearing your (xAxis.categories) if you push data into it. because highcharts don't sort your array. if you just assign new array that's ok.
(3) Note : Based on values on your categories array, navigation gets some values like xAxis min and xAxis Max. when you change your data these values remain and that's why your navigation collapses. so when changing data make sure to update. you can use 0 for minimum of navigator and categories.length for maximum value of navigator.
you can access updated values also in dataMin and dataMax.
Hope this answer help you.
I looked around a bit but can't seem to find the exact answer for this.
I'm currently adding some data to highcharts. Essentially, I am using the HighStock column and candlestick chart, and it should suffice for my testing.
The issue is this. I've set up ONE of the two series' to have IDs. I would now like to retrieve an individual point object by calling [something].get("point_0"), which seems like it should be possible but doesn't seem to work. Here is the fiddle for it:
http://jsfiddle.net/mr3ezgh9/
and here is the code:
var chart = null;
$(function () {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-ohlcv.json&callback=?', function (data) {
// split the data set into ohlc and volume
var ohlc = [],
volume = [],
dataLength = data.length,
// set the allowed units for data grouping
groupingUnits = [[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]],
i = 0;
for (i; i < dataLength; i += 1) {
ohlc.push([
data[i][0], // the date
data[i][1], // open
data[i][2], // high
data[i][3], // low
data[i][4] // close
]);
volume.push(
{
name: data[i][0],
x: data[i][0], // the date
y: data[i][5], // the volume
color: "red",
id: "point_" + i
}
);
}
// create the chart
$('#container').highcharts('StockChart', {
rangeSelector: {
selected: 1
},
title: {
text: 'AAPL Historical'
},
yAxis: [{
labels: {
align: 'right',
x: -3
},
title: {
text: 'OHLC'
},
height: '60%',
lineWidth: 2
}, {
labels: {
align: 'right',
x: -3
},
title: {
text: 'Volume'
},
top: '65%',
height: '35%',
offset: 0,
lineWidth: 2
}],
series: [{
type: 'candlestick',
name: 'AAPL',
data: ohlc,
dataGrouping: {
units: groupingUnits
}
}, {
type: 'column',
name: 'Volume',
data: volume,
yAxis: 1,
turboThreshold: Number.MAX_VALUE,
dataGrouping: {
units: groupingUnits
}
}]
});
alert(Highcharts.charts[0].get("point_0"));
});
});
I have tried a few variations on .get("point_0") like getting a series first (but the series doesn't have a get function), setting the chart to a variable and then getting it, and other similar changes, but nothing quite seems to work. Any insight on this?
The general problem is that in the highstock you have enabled datagrouping, so points are groupped and ids are skipped. Disable it and option will work.
plotOptions: {
series: {
dataGrouping: {
enabled: false
}
}
}
Example: http://jsfiddle.net/mr3ezgh9/1/
I want the gradline and the xaxis started in the same line, I tried set the yaxis.min and so on。
it don't work, so some one could help me on this?
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'text'
},
xAxis: {
categories: [],
labels: {
style: {
width: '50px',
'min-width': '50px'
}
}
},
yAxis: {
categories: [],
title: {
text: 'text'
},
min: 0,
},
series: [
{
name: 'name',
type: 'spline'
}
]
This is my chart option, and I dynamicly update the values of xAxis and yAxis, this's my update code
chart.yAxis[0].setExtremes(0, maxy);
chart.xAxis[0].setCategories(timeArr);
chart.series[0].setData(valArr);
timeArr is the string array about time, valArr is my data, maxy is max of the valArr.
In general it should work fine: http://jsfiddle.net/bteWs/31/ (try to update to 4.0.1 version)
However, I advice to remove categories from yAxis, since you want numeric values, right?
yAxis: {
categories: [], //remove that option
title: {
text: 'text'
},
min: 0,
},
