HIGH CHARTS
In addition to this question, I would like to ask another question here in this thread.
How to add extra tears(ticks), in such a way, the green bar dataLabel, does stay inside plotting area, rather, going out of plotting area or made hidden. JSFIDDLE
There are lots of ways to do this. But quickest one is adding a max value to yAxis with using yAxis.max.
yAxis: {
allowDecimals: false,
max: 6000
},
Here is the working example: jsFiddle.
OR
You can use the combination of yAxis.tickAmount and yAxis.tickInterval like this;
yAxis: {
allowDecimals: false,
tickAmount: 10,
tickInterval: 1000
},
Here is the working example: jsFiddle.
Besides setting a new max property or trying a different combination of ticks, you can simply set overflow property with 'none' value and crop with false. This way you can display data labels outside the plot area.
API Reference:
http://api.highcharts.com/highcharts/plotOptions.series.dataLabels.overflow
http://api.highcharts.com/highcharts/plotOptions.series.dataLabels.crop

If you look at the JSFiddle below, you'll see that when it renders the chart, the upper-most values are not displayed on the chart (10,000/10,000/80,0000/20,0000).
I can't seem to figure out why it doesn't display those top values.
I also noticed that it doesn't display the -20,000 value for the Weight channel.

You need to enable showLastLabel option:
yAxis: [{
...,
showLastLabel: true
}, ...]

I have a question about highchart's overlapping data labels. I have 2 spline data series and as you can see here http://jsfiddle.net/3E8V4/ some data labels are overlapping.
Question here is: is this overlapping even possible to prevent? If yes - how should I do it?
Code for plotoptions is like that:
plotOptions: {
spline: {
dataLabels: {
enabled: 'True',
crop: false,
overflow: 'none'
},
enableMouseTracking: false
}
},
You can use that plugin for repositioning dataLabels: http://jsfiddle.net/menXU/1/ It's not perfect, since works only for max 2 series and requires disabled animations, or you will see little delay when repositioning dataLabels.
How to use? Copy StaggerDataLabels and isLabelOnLabel functions, and then use StaggerDataLabels in load and redraw events for chart.
Sobis,
I don't have a answer that is exactly what you are expecting.
In this case what i would do is increase the max of yAxis by 10% of the maxi m of the data.
provide zoom in/out. that will enable the user to get a values on top of the points
zoomType: 'xy'
here is an example http://jsfiddle.net/3E8V4/1/
hope you will find it useful
Is there a programmatic way to provide axis labels for individual bars in a grouped bar chart in HighCharts?
Use case: The use case is when dealing with a graph that is both grouped and stacked. With these graphs it is hard to visually convey (without a tooltip) what the individual bars represent, unless they have individual labels.
Default behavior:
As an example see the HC demo for a stacked and grouped column graph, in which it might initially be unclear that the individual bars in each cluster represent different genders: http://www.highcharts.com/demo/column-stacked-and-grouped
Goal: Here is an illustration of what I am trying to achieve. Is it possible to do this programmatically, such as with a second x-axis? Perhaps another idea would be to use clever placement of the stack total, but of course that would get in the way of showing the actual stack total.
There are a few options which may help you.
Firstly, the stackLabels formatter allows you to determine what is in you label.
Secondly, veticalAlign:"bottom" allows you to position the labels at the bottom of the stack.
Thirdly, the 'y' option allows you to move the label relative to its default position.
The catch is that you can't seem to move the label outside of the chart plot area. One way round this is to start your y-axis at a negative value to give room for the labels. You can then move the position of the x-axis into the chart area.
http://jsfiddle.net/WY6QB/
xAxis: {
offset:-43,
labels:{
y:40
},
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
stackLabels: {
verticalAlign:"bottom",
y:20,
enabled: true,
formatter: function() {
return this.stack;
}
}
The only thing left is to try to remove the spurious '-2' y axis point.
-EDIT-
If you set startOnTick to false, and give the y-axis min as -1.9, the spurious -2 point goes away.
min: -1.9,
startOnTick:false,
http://jsfiddle.net/V6Cp2/
It is not exactly the same result as your image, but it displays the stackLabels:
yAxis: {
...
stackLabels: {
enabled: true,
formatter: function() {
return this.stack;
}
}
},
It displays the label at the top of the column.
Example
You can use grouping categories plugin.
On hiding both the series using legends, and then clicking one of the series shows xAxis starting from '-1', when ideally it should show only not null categories.
Using 'ignoreHiddenSeries: false' solves the purpose but again on hiding both the series using legend and then enabling other series tends to overlap both the series. Although on window resize event, series get aligned properly.
chart: {
type: 'column'
// ignoreHiddenSeries: false
},
Example for reference: http://jsfiddle.net/t88rc/
You can simply set for xAxis min:0, see: http://jsfiddle.net/t88rc/2/
Grouped column charts work best with equal number of data points per series.
Best solution I have found for this is to fill any missing data points with null values:
http://jsfiddle.net/jlbriggs/t88rc/1/
data: [49.9, 71.5,null,null,null,null,null,null]
I'm trying to create a column chart (Highcharts) with a fixed width (range) for all the columns. I have around 300 columns, and I want to draw them actually as lines, and that's why I assign a very small range (0.001) for each of them.
The data format is basically like this: [numberId, min, max].
However, sometimes the height is shown correctly... but some other times it appears with strange height, not even the same for all the columns. I have tried many different things but I didn't manage to find the problem.
This is the jfiddle http://jsfiddle.net/deSSf/3/ (if you resize the area for the chart you will probably see the effect). The fiddle is actually using HighStock, but this chart should be from highcharts lib.
I have screenshos but can't post them.
The code is very simple:
chart: {
renderTo: 'container',
type: 'columnrange',
},
series: [{
data: [[1,0,0.001],......]]
}
There is huge difference between Highcharts and Highstock. In Highstock you have access to dataGrouping which collects data and groups when there is to many points to display on a chart.
Disable it to have working example: http://jsfiddle.net/deSSf/4/
dataGrouping: {
enabled: false
}
