I'm wanting to create a combo line/column chart where the line points are discreetly presented (1 for each day) and then have columns with other values for a given date range (say, by month), and have the line points show in that month. Is this possible in Highcharts?
I'm guessing I'd need to create categories for the X axes (months) but am unsure how to retain the day-level detail in my line series as it seems like a 1:1 mapping?.
In the example below, is it possible to "group" the last line points between say Sept and Nov? Attempt at adding and grouping an additional (test) series to stock example:
{
name: 'Foo',
type: 'line',
data: [20, 34.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2, 90, 40, 22, 10, 12, 30, 36, 50],
pointPadding: 0.2,
grouping: true
},

Any tips appreciated

This is my chart
I need that tick start from the start of my chart, without padding left.
I tried read docs, but I couldn't find anything about it
Per the docs it should be doing this anyway with xAxis.startOnTick:
Whether to force the axis to start on a tick.
Use this option with the minPadding option to control the axis start.
Defaults to false.
So, perhaps you overwrote this in your chart code?
Update:
So, from your code what you have is a categorical xAxis and an area line chart. Stylistically* this does not make much sense as the entire category "bin" is one single value and you are putting in time values (I assume since they are ['00:00', '05:00', '05:00', '05:00', '05:00']). Why not make an actual time series xAxis? This would give discrete x positions based upon the time and you could see that area chart a bit clearer.
Sample time-based xAxis:
$(function() {
$('#container').highcharts({
chart: {
type: 'area'
},
xAxis: {
startOnTick: false,
type: 'datetime'
},
series: [{
name: 'John',
data: [0, 3, 4, 7, 2],
pointStart: Date.UTC(2010, 0, 0),
pointInterval: 5 * 3600 * 1000 // 5 hour
}, {
name: 'Jane',
data: [2, -2, -3, 2, 1],
pointStart: Date.UTC(2010, 0, 0),
pointInterval: 5 * 3600 * 1000 // 5 hour
}, {
name: 'Joe',
data: [3, 4, 4, -2, 5],
pointStart: Date.UTC(2010, 0, 0),
pointInterval: 5 * 3600 * 1000 // 5 hour
}]
});
});
What I mean "stylistically" is that you have hard breaks from "00:00" to "05:00". So let's assume that is 5 hours between categories. Does an area plot really convey any information to the user since you have a 5 hour gap between points? Wouldn't a simply column chart make more sense here? If this is even 5 minutes between categories it seems a little iffy to make this an area chart.
I am a bit confused by the documentation regarding the notation for point values when it comes to 3+ value charts such as HeatMap and BoxPlot.
I see that point values can be supplied as n length arrays:
data: [
[760, 801, 848, 895, 965],
[733, 853, 939, 980, 1080]...
]
And that they can be config objects with additional/custom properties:
data: [{
name: 'Point 1',
color: '#00FF00',
x: 1,
y: 3
}, {
name: 'Point 2',
color: '#FF00FF',
x: 2,
y: 5
}]
But how does one use the config object notation for HeatMap/BoxPlot when the only documented value properties seem to be 'x' and 'y'?
Is there a supported property of the config object that will be interpreted as the n length array? Something like this?
data: [{
name: 'Point 1',
color: '#00FF00',
values: [1,2,3]
}, {
name: 'Point 2',
color: '#FF00FF',
values: [4,5,6]
}]
It depends on the type of chart.
For HeatMap (reference):
A heat map has an X and Y axis like any cartesian series. The point definitions however, take three values, x, y as well as value, which serves as the value for color coding the point. These values can also be given as an array of three numbers.
In other words you could do { x: 0, y: 1, value: 10 } or [0,1,10].
For BoxPlot (reference):
Each point in a box plot has five values: low, q1, median, q3 and high. Highcharts recognizes three ways of defining a point:
Object literal. The X value is optional.
{ x: Date.UTC(2013, 1, 7), low: 0, q1: 1, median: 2, q3: 3, high: 4 }
Array of 5 values. The X value is inferred.
[0, 1, 2, 3, 4]
Array of 6 values. The X value is the first position.
[Date.UTC(2013, 1, 7), 0, 1, 2, 3, 4]
I'm trying to create a stacked bar chart with a Y axis as a percentage (0-100%) and the X axis multiple separate stacks. The data for each stack is independent and has no relationship to the other stacks.
e.g.
Stack 1 = Animals [10, 20, 30 , 40]
Stack 2 = Cars [10, 30]
Stack 3 = Aeroplanes [10, 20, 30, 40, 50, 60, 70]
Is this achievable?
This is what I have so far.
http://jsfiddle.net/carlskii/f3EK8/
For each series, you can set stack: id
Like this:
series: [{
stack: 'aeroplanes',
name: 'Prop Planes',
data: [25],
color: 'green'
}]
Stacks with the same ID will be grouped together.
Highcharts does a great job figuring out appropriate tick intervals.
However, I have a "duration" series (in ms), which I format e.g. like "3y 6M" or "1d 3h" or "3h 30min" for display. Because Highcharts is optimizing the tick intervals for the ms value (e.g. 10,000,000ms), I end up with awkward values such as [ 2h 46min 40s, 5h 33min 20s, 8h 20min ] rather than [ 3h, 6h, 9h ].
Can I get Highcharts to prefer multiples of certain values (e.g. 1000, 60 * 1000, 60 * 60 * 1000 etc)? I'd rather not have to calculate the exact tick interval myself (depends on chart size etc).
I think you should consider using datetime axis for yAxis. For example: http://jsfiddle.net/jRGvs/
yAxis: {
type: 'datetime'
},
series: [{
type: 'column',
name: 'Column',
data: [Date.UTC(1970, 0, 1, 2, 30),
Date.UTC(1970, 0, 1, 1, 45),
Date.UTC(1970, 0, 1, 4, 10),
Date.UTC(1970, 0, 1, 3, 30)]
}]
you can go with label > formatter for yAxis,
here you can write a routine which will handle the text/value to be displayed beside the grid line. but the thing is you cannot override the tick interval from here.
As shown in the picture (which is not the same code as the fiddle, but exhibits the problem), with Highcharts new bubble charts it seems like dataLabels like to sit on top of each other. Is there an easy workaround for this? I'd be happy to manually change the z-index on a per label basis, but this doesn't seem to work for bubble charts. Here's some sample code that fails to work as expected (try it in a fiddle):
series: [{
data: [{
x: 99,
y: 36,
z: 50
}, {
x: 99,
y: 74,
z: 55,
dataLabels: {
zIndex:15,
enabled: true,
}
}, {
x: 99,
y: 76,
z: 55,
dataLabels: {
zIndex: 1,
enabled: true
}
}
]
}],
You can set useHTML: true flag, and then set z-index: x property for dataLabels, see: http://jsfiddle.net/ZLmU8/4/
Apparently there is a labelrank property on the Highcharts point objects that can be used to dictate which point labels are on top. It can be used when you're creating your data like this:
data: [{
x: 1, y: 1, labelrank: 1, name: 'A'
},{
x: 1, y: 1, labelrank: 2, name: 'B'
}]
Or it can be updated on an individual point to bring that point's dataLabel to the front by doing something like this: chart.series[0].points[0].update({labelrank: 3});
I had a similar issue and created this question on SO that just was answered.
Edit
They have added info regarding series.data.labelrank to their docs as well: http://api.highcharts.com/highcharts#series.data.labelrank
