On refining my problem statement, I came up with a column stacked stock chart.
I have set the plotOptions.series.pointPlacement to on for my application. Now the issue is that only half columns are plotted for first and last data.
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
},
series: {
pointPlacement: "on"
}
},
Please refer to the fiddle: http://jsfiddle.net/vbjdF/
I need to somehow make sure the entire columns are plotted without truncating the columns. Any help is appreciated.
Thanks in advance.
Indeed it looks like a problem, so I reported to our developers https://github.com/highslide-software/highcharts.com/issues/1933, please stay on track with this thread.
You can add 0 values as first and last point, and add empty categories.

You can add type: 'category' for the xAxis instead of adding an array of empty categories

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

I have a script that produces a Highcharts column graph. This working perfectly and display the percentage at the top of each data column.
If I then export it to a PDF using the Highcharts export function the percentage is displayed twice on each column.
Does anyone have any idea why this happends.
As I say the on screen display is fine.
Many thanks in advance for any pointers.
you need to set textShadow as false, see below :
plotOptions: {
series: {
dataLabels: {
style: { textShadow: false },
}
}
}
here is demo with your previous question's data
EDIT: Related topic on github: https://github.com/highslide-software/highcharts.com/issues/3649
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.
I am trying to increase the space between charts in this link however i have used minPadding/maxPadding in xAxis and pointWidth: 90/pointPadding: 0 but nothing works. It seems to me that there is forced spacing at the top and bottom of the chart area which is causing this.
http://jsfiddle.net/j7NMC/2/
/*What i have tried */
series:{
pointWidth: 90,
pointPadding: 0
}
xAxis: {minPadding:0, maxPadding:0,}
Any ideas?
Thank you :)
I would suggest changing your data setup. Instead of 3 different series, use 1 series and 3 categories:
series: [{
data: [973,133,107]
}]
example: http://jsfiddle.net/j7NMC/4/
What this does for you:
1) eliminates that wasted space on the chart
2) eliminates need for legend by putting the labels right on the axis next to the bar (drastically improves usability of chart, makes comprehension much easier for user)
3) eliminates need for multiple colors for the bars (drastically improves usability of chart, makes comprehension much easier for user)
EDIT:{
you can try setting the groupPadding to 0 to remove some of the space, as the the 3 series you have displayed are grouped, and extra space is being added because of that.
The options need to be in the 'bar' section of plotOptions, and you don't need a series entry in plotOptions i.e. like this:
plotOptions: {
bar: {
dataLabels: {
enabled: true
},
pointWidth: 10,
pointPadding: 0
}
},
