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],
]
}]
});

Hello Highcharts and stackoverflow,
I would like to make it easy for end users to compare wedgets in a Variable radius pie chart (basically the same as Line to the Y axis on hover but radial). As such, when they hover on a wedge, I would like to draw a "ring" around the circle for easy comparisons. This would be appear/disappear/change based on which point you are hovering on.
(in some ways - like a mix between the visualization of the Variable radius pie chart with the concept of an axis like a Polar/Radar Chart)
Any ideas?
Use column series in polar chart with crosshair:
chart: {
polar: true
},
series: [{
type: 'column',
pointPadding: 0,
groupPadding: 0,
colorByPoint: true,
data: [...]
}],
yAxis: {
crosshair: {
color: 'red',
zIndex: 3
}
}

Can someone help me to understand what is wrong here. Everything seems perfect.
http://jsfiddle.net/prakash4mail/nt86gj7z/1/
$(function () {
$('#container').highcharts({
chart: {
type: 'heatmap',
},
colorAxis: {
min: 0,
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[0]
},
series: [{
borderWidth: 1,
data: [[2020-04-01, 18000, 29060],[2020-04-01, 18500, 9920],[2020-04-01, 19000, 32160],[2020-04-02, 18000, 12400],[2020-04-02, 18500, 91880],[2020-04-02, 19000, 54000],[2020-04-03, 18000, 63540],[2020-04-03, 18500, 43420],[2020-04-03, 19000, 43420]],
dataLabels: {
enabled: true,
color: '#000000'
},
}]
});
});
heatMap showing lines instead of squares
The exact answer is rowsize: 500 (from UI perspective - height, YAxis difference between each point) and colsize: 86400000 (one day each, x-axis difference between each point). Missing this was causing box not to appear.
As I understood you would like to achieve something like is rendered here: http://jsfiddle.net/BlackLabel/o6ywag42/
Notice how the data structure looks like in this demo from Highcharts demo base:
https://jsfiddle.net/BlackLabel/uofntb4y/ - if you want to keep the points as a square the 'y' value must be growing one by one, like here: http://jsfiddle.net/BlackLabel/o7bgq1pu/
And to show your truly y scale you can use the categories feature.
yAxis: {
categories: ['18000', '18500', '19000']
},
API: https://api.highcharts.com/highcharts/yAxis.categories
EDIT:
Another solution suggested by #prakash is to use the series.rowsize property and series.colsize to fit the squares.
API: https://api.highcharts.com/highcharts/series.heatmap.rowsize
API: https://api.highcharts.com/highcharts/series.heatmap.colsize
I have a column highcharts chart that I am trying to enable zooming on. The issue I am having is that when I try and zoom in on a small slice of the chart it always zooms to 200 and not smaller. How can I get it to zoom into the x area I have actually selected? Here is a fiddle showing the issue.
https://jsfiddle.net/3gh40fpy/
Highcharts.chart('container', {
yAxis: {
min: 0,
max: 1.1
},
series: [{
name: 'series',
data: [
[1, 0.4648303],
[38.6, 0.3659616331],
[76.2, 0.1323167732],
[113.8, 0.0300049188],
[151.4, 0.0049188392],
[189, 0.0009837678],
[226.6, 0.0004918839],
[264.2, 0],
[301.8, 0],
[339.4, 0.0004918839],
[377, 0]
]
}],
chart: {
type: 'column',
zoomType: 'x'
}
});
In case of your chart you should be able to use xAxis.minRange parameter for changing the minimum range to display on xAxis axis:
Documentation:
http://api.highcharts.com/highcharts/xAxis.minRange
xAxis: {
minRange: 1
},
http://jsfiddle.net/xLzvn73o/
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]
]
}]
});
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.
http://api.highcharts.com/highcharts#yAxis.reversed
reversed: true
