Highcharts Ganttchart (or XRange) group y-Axis elements - highcharts

I need to group elements on the y-Axis and not sure how to achieve this. It can be with x-range or gantt, with category, grid or treegrid, whichever works best.
Here's an example

You can use Grouped Categories plugin:
yAxis: {
...,
labels: {
groupedOptions: [{
rotation: -90,
}],
},
categories: [{
name: "Fruit",
categories: ["Apple", "Banana", "Orange"]
}]
}

Is It possible to plot a water fall chart as shown in the below image?

I need to plot a waterfall chart like below. In the chart, each column is a type of category and the value is calculated by adding the sub-types. How do we display the sub-types(ex: Gas 1, Gas 2) in the bottom and category(like Category 3) in the top. Is this possible in highcharts?
You can use two xAxis with categories. For example:
xAxis: [{
opposite: true,
lineWidth: 0,
categories: ['Start', 'Category1', 'Category2', 'Category3', 'Category4', 'Balance']
}, {
linkedTo: 0,
lineWidth: 0,
categories: ['', 'Sub-Category 1', 'Liquid 1<br>Liquid 2', 'Gas 1<br>Gas 2', 'Solid 1', ''],
labels: {
rotation: 0,
y: -10
}
}]

Highchart line chart with category do not occupy full width

I'm using Highchart to generate a line chart with data labels. Here is an example of what I'm doing:
Highcharts.chart('container', {
title: {
text: 'Chart without categories'
},
xAxis: {
categories: ['a','b'],
},
series: [{
data: [1,2]
}]
});
This code generates the following chart: As you can see, there is a space between the line and and the borders of the chart.
Without using categories, there is no space:
What can I do to remove this spaces?
That is a default behavior of category axis type. Please check this example: http://jsfiddle.net/BlackLabel/wuqxb2cy/ with a more visible distribution into categories.
As a solution you can set xAxis.tickmarkPlacement and series.pointPlacement to 'on':
xAxis: {
categories: [...],
tickmarkPlacement: 'on'
},
series: [{
data: [...],
pointPlacement: 'on'
}]

Highcharts inverted column chart - descending tickPositions

I would like my chart to start from a set threshold (3 in my example - the middle). If i set my tickPositions in ascending order ([1,3,5]) the chart displays fine.
xAxis: {
categories: ['Cat1', 'Cat2']
},
yAxis: {
tickPositions: [1,3,5]
},
plotOptions: {
series: {
threshold: 3
}
},
series: [{ name: 'Demo', data: [2, 4] }]
But if i set my tickPositions in a descending order ([5,3,1]) it seems like the threshold gets ignored.
yAxis: {
tickPositions: [5,3,1]
},
JS Fiddle link
I would not specify the tickPositions out of order - it is not intended to work that way. Instead, specify them in the proper numeric order, and use the yAxis.reversed property.
Example:
yAxis: {
reversed: true,
tickPositions: [1,3,5]
}

Can I use two "categories" arrays in a stacked bar chart?

I'm using a stacked percentage bar chart in Highcharts. (This jsfiddle is similar to our chart, derived from an example on the Highcharts site.)
What I'd like to do is add another set of "category" labels on the right side of the chart. Where the left side has labels for each bar, I'd like to show an average on the right. (Calculating this average and putting it in the Highcharts configuration data is done on the server side; in the fiddle I've just hard-coded some dummy values.)
I've tried using multiple x-axis configurations, with the averages categories marked opposite: true to put them on the right side. I can see that adding this is changing the chart, especially if I don't put them on opposite, but the labels don't actually show in any configuration I've tried. Is this possible? If so, what do I need to do that I'm not yet doing?
This is the configuration in the jsFiddle example:
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Stacked bar chart'
},
xAxis: [{
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
}, {
title: 'Avg.',
categories: [3.0, 3.3, 3.6, 2.6, 3.0],
opposite: true
}],
yAxis: {
min: 0,
title: {
text: 'Percent fruit consumption'
}
},
plotOptions: {
series: {
stacking: 'percent'
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});
You have the correct axis set up, but currently the chart doesn't know what to do with the second axis.
Highcharts requires that an axis has either a data series attached to it, or that it is linked to another axis that does, in order to display it.
If you add a linkedTo property, it will work as required:
xAxis: [{
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
}, {
linkedTo: 0, // <-- now the chart will show it, as long as axis 0 is able to be shown
title: 'Avg.',
categories: [3.0, 3.3, 3.6, 2.6, 3.0],
opposite: true
}]

Highcharts scatter chart with a name per point

I'm trying to tweak a Highcharts scatter plot with this date series
series: [{
data: [[1,2],[2,5]]
}]
so that i can put a name on each point, I want to show the name in the tooltip.
The API doc says an object of named values can be defined like this
series: [{
data: [{
name: 'Point 1',
x: 1,
y: 2
}, {
name: 'Point 2',
x: 2,
y: 5
}]
}]
but it seems the x and y values are not picked up. See my jsfiddle example.
This answer works for Highcharts 4.1.9.
Took me a long time to figure out hence I want to pass it on in case someone is looking for this as well.
Your mileage may vary for other versions.
plotOptions: {
scatter: {
dataLabels: {
format: "{point.name}",
enabled: true
},
enableMouseTracking: false
}
},
series: [{
name: 'Projects',
data: [{"name":"Point 1", "x":1,"y":2}, {"name":"Point 2", "x":4,"y":5}]
}]
What are the key points?
Ensure that the scatter.dataLabels is enabled and the format is {point.name}
Ensure that the data is in the format of {"name":"Point 1", "x":1,"y":2}
As mentioned in this comment, what works for me in Highcharts 5.0.6 is:
{
type: 'scatter',
tooltip: { headerFormat: '<strong>{point.key}</strong><br>' },
data: [{ x: 0, y: 1, name: 'Whatever' }, ...]
}
As stated in the documentation, the name field is the name of the point as shown in the legend, tooltip, dataLabel, and so on. I updated your fiddle to include the highcharts library, and I am seeing this behaviour (i.e. if I hover over a point, its label is displayed).
If you want the x-axis labels set correctly, you need to ensure that the xAxis section of your chart configuration does not have a categories key.
You could also show names in the legend section. Updated the selected answer above here
series: [{
name: 'Point 1',
data: [[3, 3]]
}, {
name: 'Point 2',
data: [[4, 8]]
}, {
name: 'Point 3',
data: [[9, 15]]
}]
This is a new feature in HighCharts 3.0. You have to define the xAxis type to 'Category' and give the name of the point in the data if you want it to appear on the xAxis:
xAxis: {
//categories: ['Green', 'Pink'],
type: 'category'
},
...
data: [{
name: 'Green',
x: 1,
y: 2
}, {
name: 'Pink',
x: 2,
y: 5
}]
See your jsFiddle code updated :here.
Note that I have added the tooltip formating feature to show that point.x has no more meaning in this context, only point.name remains relevant. Also, you cannot have two points with different 'name' at the same x position.
I struggled with this issue and after finding the solution in the documentation I must say the behavior as designed feels a bit unexpected.
Per the docs (here: https://api.highcharts.com/highcharts/plotOptions.scatter.tooltip), the tooltip does not show all fields you can add to a data point, but rather
Defaults to x: <b>{point.x}</b><br/>y: <b>{point.y}</b><br/>.
To show the data point name (and any other fields you want to), simply change the HTML rendered by the tooltip. For example, you can display the point name and coordinates in the tooltip while removing the series name as follows:
chart: {
type: "scatter",
}
tooltip: {
headerFormat: '',
pointFormat: 'Name: <b>{point.name}</b><br/>Load time: <b>{point.y}</b><br/>Requests: <b>{point.x}</b>',
},
