I want to make a stacked column chart with age intervals.
I have a two-dimensional array containing an age key and a value.
The idea is: every single age is stacked on top of each other within their interval, and thereby represent the accumulated number of people within the age interval in a single column.
I want to approach this solution with highcharts' stacked column chart example.
This is my code so far:
// Age stacked column chart.
var ageData = [
[0, 0], [1, 0], [2, 0], [3, 0], [4, 0], [5, 0], [6, 0], [7, 0], [8, 4], [9, 3],
[10, 24], [11, 33], [12, 31], [13, 21], [14, 61], [15, 42], [16, 43], [17, 87], [18, 64], [19, 120],
[20, 134], [21, 142], [22, 184], [23, 221], [24, 234], [25, 211], [26, 198], [27, 94], [28, 79], [29, 34],
[30, 24], [31, 27], [32, 32], [33, 21], [34, 4], [35, 7], [36, 11], [37, 5], [38, 3], [39, 6],
[40, 3], [41, 4], [42, 13], [43, 6], [44, 4], [45, 3], [46, 1], [47, 2], [48, 2], [49, 0],
[50, 0], [51, 34]]
$('#container_stackedColumn').highcharts({
chart: {
type: 'column'
},
title: {
text: 'User age distribution'
},
xAxis: {
categories: [
'0-12',
'13-18',
'19-23',
'24-28',
'29-35',
'36-42',
'43-50',
'>50'
]
},
yAxis: {
min: 0,
title: {
text: 'Number of users'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
style: {
textShadow: '0 0 3px black, 0 0 3px black'
}
}
}
},
series: [{ /* --- What to do here?! --- */ }]
});
So, with my two-dimensional array in consideration, how do I visualize this stacked column chart?
Any help is greatly appreciated. :)
You need to itearate on you arrays, compare with the limits which you have (categories) and push to correct series array.
See the parser (http://jsfiddle.net/W6AFY/3/) hope that it is correct.
Or another solution, using different series for each part of bar: http://jsfiddle.net/s9qHH/48/
var ranges = [12, 18, 23, 28, 35, 42, 50, 1000],
rangesLen = ranges.length,
series = [];
$.each(ranges, function(i, e){
series.push({ //create series' containers for legend
id: e+'index',
name: e
});
});
$.each(ageData, function(i, e){
var x = e[0],
y = e[1],
index = 0;
while(ranges[index] < x){ // get category index
index ++;
}
series.push({
showInLegend: false,
linkedTo: ranges[index] +'index', // link to container series
data: [ [index, y] ] //add point at specific category
})
});
Still, I think that's Sebastian's solution is faster.

I suggest to add new series, with different xAxis, series.columnrange.xAxis. To styling you have options to adjust like xAxis.left and xAxis.top.
chart: {
type: 'columnrange',
},
xAxis: [{
width: '33%',
offset: 0,
}, {
left: '50%',
width: '33%',
offset: 0,
}],
plotOptions: {
xAxis: {
labels: {
enabled: true
}
},
columnrange: {
grouping: false,
dataLabels: {
enabled: true,
}
}
},
series: [{
name: 'Joe',
color: '#E5DDE3',
data: [
[-5, 5],
[-10, 10],
[-13, 13],
[-16, 16],
[-19, 19]
]
},
{
name: 'Jane',
color: '#BEA9BA',
data: [
[-3.5, 3.5],
[-6, 6],
[-7, 7],
[-9, 9],
[-12, 12]
]
},
{
color: '#A5879E',
name: 'John',
data: [
[-1.5, 1.5],

},

xAxis: 1,
data: [
[-5, 5],

To control each series you need to write a custom legend control, for this you can use legend.labelFormatter, that give you callback function to format each of the series' labels.
EDIT ------
To control many group series I used callback function events.legendItemClick builded in series events. They give way to manage series at legend in that case I compare name of series and index of items to hide and show group of series with custom legend.
events: {
legendItemClick: function() {
let name = this.name.substring(this.name.length - 1, this.name.length);
let _i = this._i;
this.chart.series.forEach(function(p, i) {
console.log('p: ', p, 'i: ', i);
if (name === p.name.substring(p.name.length - 1, p.name.length) && _i !== p._i) {
(!p.visible) ? p.show(): p.hide()
}
})
}
}

In a project, I want to work with Highcharts, but instead of putting the options code directly on to the website I rather would like to see it in an extra file, e.g. charts.js. Is it possible?
What I have done so far:
I created the general chart and it works. I tried to put the options code as shown on Highcharts in a file called charts.js and include it into the header. But it doesn't work, shows an error #13.
The code I used was
function getPointCategoryName(point, dimension) {
var series = point.series,
isY = dimension === 'y',
axis = series[isY ? 'yAxis' : 'xAxis'];
return axis.categories[point[isY ? 'y' : 'x']];

Is there a way to put the code into a fail and let it work as it would if code, CDN and Co. are on one page? Or is there anything I do wrong?
Highcharts error #13 means that Highcharts is unable to find the HTML element to render the chart in. From your description it looks like your script is fired before DOM is fully loaded. As a solution put all your code from chart.js file into DOMContentLoaded event callback function:
window.addEventListener('DOMContentLoaded', (event) => {
// chart.js
});
Or just put your script before the closing </body>:
<html>
....
<body>
....
<script type="text/javascript" src="chart.js"></script>
</body>
</html>
I wan't to create a heatmap for different days and months, but i run into a problem that xAxis doesn't change when i add aditional element in array it can have only 10 elements but i need 12.
The same problem with yAxis that is only 5 elements, but i need to add 7 in total.
After adding another element to X or Y axis - nothing happening.

If you want to use categories you will need to add the new values to the category array.
Next, you will need to add wanted points. Notice that array looks like this: [x, y, value], so if you want to increase the yAxis labels you will need to add an additional point for each category.

I want a chart like this, with labels in it. And I wish have in all of them.
What I'm missing?
You have to create and place the data value labels yourself. How to do this can be seen in this answer.
I created a fiddle adjusting it to your code. Only the first data series (foo) has labels for now. you will have to adjust the position. The relevant code:
$.each(plot.getData()[0].data, function (i, el) {
if (el.length > 1) {
var o = plot.pointOffset({
x: el[0],
y: el[1]
});
$('<div class="data-point-label">' + el[1] + '</div>').css({
position: 'absolute',
left: o.left + 4,
top: o.top,
'text-align': 'center',
display: 'none'
}).appendTo(plot.getPlaceholder()).fadeIn('slow');
}
});
But you may also have to cleanup your data. You have multiple data points with the same x values (which means bars behind / in front of each other which leads to some being invisible). Take a look at the side-by-side and stack plugins on the flot plugin page.
Issue with my xaxis ticks, only the first tick shows at the far right of the graph, and no bars are plotted. I have a feeling i'm missing something obvious.
Desired solution: Show all the xaxis ticks and plot the bars accordingly
Associated code:
$.plot($("#chart"), results, {
grid: {
hoverable: true,
aboveData: true
},
xaxis: {
ticks: [
[1, "AL"],
[2, "AZ"],
[3, "CA"],

JSFiddle: http://jsfiddle.net/emaM7/
I think the problem may be simply that you're using non-numeric X values in your data. I added this code before the plot call:
for (i = 0; i < results.length; i++) {
for (j = 0; j < results[i].data.length; j++) {
results[i].data[j][0] = j;
}
}
with this a graph shows up as do the labels.
You'll probably want to use slightly more complex logic to select the proper numeric code for each state, as what I wrote won't work if you have states missing or out of order in the 'results' object.
