Is it possible to invert the y-axis, but not the data? I have a ranking which should start with 1 at the top, not at the bottom, but the columns should stay just normal.
Thanks for any hints!
You can use reversed yAxis, and column series, where each point will have y and low values, where low values are the same as the lowest number. See: http://jsfiddle.net/JVNjs/303/
var max = 10;
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
title: {
text: 'Chart Title'
},
credits: {
enabled: false
},
yAxis: {
min: 0,
max: max,
tickInterval: 2,
reversed: true
},
series: [{
type: 'column',
data: [{
y: 1,
low: max
}, {
y: 3,
low: max
}, {
y: 6,
low: max
}]
}]
There is no good easy direct way to do it (afaik).
There are a variety of approaches you could take, however.
This example uses a reversed axis and stacked columns:
http://jsfiddle.net/jlbriggs/JVNjs/301/
stacking:'normal',
It relies on adding a second series that is the difference between your value and the max, which means you must also specify a y axis max.
I left the second series a light grey so you can see them, but you can set their opacity to 0 so that they are invisible.
Other options might include doing some calculations on the y axis label formatter to display the axis labels as you want without having to touch the data.
Highcharts provides an option for this called reversed setting it true will do the work for you.

reversed: true

I have here https://jsfiddle.net/ezhp5a4j/6/ an area and a stacked bar chart But I need to achieve something like : adding another series:column behind this actual but not stacked, starting from jan. 2010 and end dec. 2010 with a certain position in y axis, my need is quiet simple, but I don't know how achieve, I think I need another X axis ?
Actually I have:
xAxis: {
type: 'datetime',
ordinal: false
},
Maybe I need add array to this or so?
You could do this with a second axis, but it's not necessary.
If you add your new data series, with some additional parameters to control the size and spacing, it can all use the same x axis.
Example:
{
"name": 'Summary',
type: 'column',
grouping: false, <-- make sure they don't group with the other series
stacking: false, <-- make sure they don't stack on the other series
color: 'rgba(0,0,0,0.5)',
pointRange: 86400000 * 365, , <-- 1 year; set to desired time frame
pointInterval: 86400000 * 365, <-- 1 year; set to desired time frame
pointPadding: 0.01,
groupPadding: 0,
data: [10000, 15000, 9000, 13000]
}

Output:
EDIT for comment:
To add a second axis, you change the xAxis object to an array of objects, like this:
xAxis: [{
type: 'datetime',
ordinal: false
},{
linkedTo: 0,
type: 'datetime',
ordinal: false
}]
If they are going to have different scales, I am not sure that it makes any sense to plot them together, but in that case, you would remove the linkedTo: 0
Then, in your data, you need to specify which data series are plotted on the second axis, by adding xAxis: 1 to the series options (you don't need to specify xAxis: 0 for the other series, as 0 is the default.
Since you have specified a pointStart in your plotOptions, if the series plotted on the second axis will have a different scale, you will need to specify a separate pointStart in that series options.

I'm working with this chart, and the thing I'm trying to create is that for example "Apples" bar does not start from 0 on y axis. Instead of that, I want it to start from from example 25%, and to end in 75% (so that bar in chart (its height) is from 25 to 75, when you look at values in y-axis). Does anyone have an idea of how to do that? What to change?
You can use the column range chart type. See this official demonstration.
Here is a sample of your apples (JSFiddle):
$('#container').highcharts({
chart: {
type: 'columnrange'
},
xAxis: {
categories: ['Apples']
},
yAxis: [{
min: 0,
max: 100
}],
series: [{
data: [
[25, 75],
]
}]
});
I'm drawing a really simple line chart with hours slept each day. So hours are on the y axis and dates on the x axis. The y axis goes from 0 to 23, but interesting values are usually between 3 and 12, so I only want to draw these values. This is easy, just define min and max on yaxis.
But now highcharts will still draw values above and below the min and max y valus. What I want is to have it just draw values above 12 on the 12 max grid line, and show the real value in the tooltip, and the inverse for values below 3.
Illustration of problem: https://jsfiddle.net/HhP39/10/
$(function () {
$('#container').highcharts({
chart: {},
yAxis: {
title: {
text: 'Hours'
},
min: 3,
max: 12,
tickInterval: 1
},
series: [{
data: [2,6,13,4,9,12,6,8,1,15,9,7,5,8,14,5,8,2,3]
}]
});
});
As you can see, values just out of range, such as 2, will still produce a tooltip if you hover over where they are. I want all values like these to move to be on the min and max lines.
Anybody got any ideas?
Take a look at this update to your fiddle: https://jsfiddle.net/HhP39/7/
It's creating an array of the original values and then an array of the adjusted values. The graph actually charts the adjusted values but the tooltip pulls from the original values.
data = [2,6,13,4,9,12,6,8,1,15,9,7,5,8,14,5,8,2,3];
series = [];
tooltips = [];
for (var i in data) {
tooltips.push(data[i]);
series.push( Math.max(3, Math.min(data[i], 12)) );
}
And then chart it with:
$('#container').highcharts({
chart: {},
yAxis: {
title: {
text: 'Hours'
},
min: 3,
max: 12,
tickInterval: 1
},
tooltip: {
formatter: function() {
return ('Real value: ' + data[this.x]);
}
},
series: [{
data: series
}]
});
I am using Highstock charts, and there is a requirement to show line graphs with a fixed x-axis range, irrespective of the data. Setting the xAxis min and max properties accomplishes that for me.
The trouble comes when I try to use the navigator. The API documentation says that the you can include an xAxis object in the navigator options which can contain all of the same properties, but here, setting the min and max properties doesn't seem to do anything: the xAxis on the navigator still begins and ends at the data min and data max. Instead, I'm trying to get it to use the same xAxis settings as the main chart.
I've thought about inserting fake data points into the series at the desired min and max (with a value of null), but was hoping there was a better way to accomplish this.
A simple example can be found here: http://jsfiddle.net/j6GFq/2
$('#container').highcharts('StockChart', {
chart: {},
navigator: {
xAxis: {
min: 0,
max: 100,
ordinal: false
}
},
xAxis: {
ordinal: false,
min: 0,
max: 100
},
rangeSelector: {
enabled: false
},
series: [{
data: [
[10, 20],
[20, 40],
[50, 10]
]
}]
});
I have a very simple example using Highcharts which uses "datetime" on one axis and categories on the other. It renders with no points and does not show the categories labels at all. I'm wondering now if you can't use that combination of types. Here is the code:
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
xAxis: {
type: 'datetime'
},
yAxis: {
categories: ['p1', 'p2']
},
series: [{
type: 'scatter',
data: [
{
name: 'Deliv1',
x: Date.UTC(2011,0,1),
y: 'p1'
},
{
name: 'Deliv2',
x: Date.UTC(2012,0,1),
y: 'p2'
}
]
}]
});
The answer to my problem was given on the highcharts forum. I thought I'd report back here what the solution was. I was errantly using y: 'p1' and y: 'p2' for values on the points. The y values actually are the indexes of the categories. Here is the updated code which works:
data: [
{
name: 'Deliv1',
x: Date.UTC(2011,0,1),
y: 0
},
{
name: 'Deliv2',
x: Date.UTC(2012,0,1),
y: 1
}
]
It's possible but you'll need to pretend the y values are numeric.
Probably by having an array with the actual Y-value and a number (maybe index) then the point's y value to the number and for the y-axis settings add the label's formatter to return the actual y-value based on the value.
You'll also need to adjust the min, max, interval and if you're using tooltips add a similar formatter to get the y-value.
(If I get more time, I'll try to create an example).
