I\'ve got a simple chart showing candlesticks with volume columns underneath: http://jsfiddle.net/T83Xy/
Basically, I want to use black and red for the columns depending
At first, you need to set series.turboThreshold to 0 if you have a big amount of points. This will disable the input data format check.
Then, to apply column colors depending on candles, I suggest you this piece of code:
Highcharts.seriesTypes.column.prototype.pointAttribs = (function(func) {
return function(point, state) {
var attribs = func.apply(this, arguments);
var candleSeries = this.chart.series[0]; // Probably you'll need to change the index
var candlePoint = candleSeries.points.filter(function(p) { return p.index == point.index; })[0];
var color = (candlePoint.open < candlePoint.close) ? '#FF0000' : '#000000'; // Replace with your colors
attribs.fill = state == 'hover' ? Highcharts.Color(color).brighten(0.3).get() : color;
return attribs;
};
}(Highcharts.seriesTypes.column.prototype.pointAttribs));
Be careful as this code will affect ALL of your charts that currently on page. But you can easily add some conditions to run this only on specific chart. Here is a default Highstock demo with the code above.
The current (HighCharts 7+) solution for this, which doesn't require overriding any methods, is to simply set the color
attribute for the volume point according to the comparison between the current candlestick point's open and its close: green if <
, red if >
, and yellow if equal.
Here is a minimal example.
// Return a color matching the candle by comparing the open (1) and close (4)
function volumeBarColor(point) {
if (point[1] < point[4])
return 'green';
if (point[1] > point[4])
return 'red';
return 'yellow';
}
Highcharts.getJSON('https://www.highcharts.com/samples/data/aapl-ohlcv.json', data => {
// Split the data set into ohlc and volume
const ohlc = [],
volume = [];
for (let i = 0; i < data.length; 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({
x: data[i][0], // the date
y: data[i][5], // the volume
color: volumeBarColor(data[i]),
});
}
// Create the chart
Highcharts.stockChart('container', {
title: {
text: 'AAPL Historical'
},
yAxis: [{
labels: {
align: 'right',
x: -3
},
height: '60%',
}, {

top: '65%',

This worked perfectly for me:
$(function () {
jQuery.getJSON('https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-ohlcv.json&callback=?', function (data) {
// split the data set into ohlc and volume
var volumeColor = '';
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
]);
if (i==0) {
volumeColor = '#CCCCCC';
} else {
if (data[i][1] >= data[i-1][1]) {
volumeColor = '#006633';
} else {
volumeColor = '#CC0033';
}
}
volume.push({
x: data[i][0], // the date
y: data[i][5],
color: volumeColor
});
}
// create the chart
