I am making a Line in highchart where there are between one and two objects and each object has multiple lines associated with it. My issue is I want my legend to look like this:
Where color represents the object and opacity represents the actual line on the graph. I couldn't figure out how to get the object labels "Thing one" and "Thing two" in the right place, but I hacked it together by putting the object name in the first series title and got a legend that looks like this:
This isn't the best solution, but I would be ok with it except for the fact that when the chart is resized, the line breaks in arbitrary places:
making it confusing to read. Is there a way to set the line break so that the different objects are always on different lines if the chart is resized:
Also open to suggestions on better ways to represent this legend.
I was able to achieve this by setting the legend itemWidth and width property:
legend: {
enabled: true,
itemWidth: 400,
width:400,
align: 'center'
}

Already I have created a normal yAxis plotline with label styles.But now I want to create a yAxis plotline with some CSS styles. Any Suggestions?
This is what i have tried so far
This is my code
var chart = $('#tv_chart_container').highcharts();
chart.yAxis[0].removePlotLine('hori_line');
data = chart.series[0].data;
var test = data.length;
var value = data[999].y;
chart.yAxis[0].addPlotLine({
value: value, // Value of where the line will appear
width: 2 ,
color: '#248EC6',
// dashStyle: 'dash',
id: 'hori_line',
label: {
text: value,
align: 'right',
style: {
color: '#FFFFFF',
fontWeight: 'bold',
}
}
});
Here is the sample.What i actually need
I worked up a proof-of-concept that gets pretty close to what you're asking. This is using all code within Highcharts, and not anything dealing with outside CSS.
Plot lines can't possess the data label formatting you're seeking, so I used a scatter plot series to serve as the line instead. Plus, this also gives you the (default) Highcharts animation when you move over a new point in your line graph.
I did a few things here:
I added the scatter plot line as a separate "dummy" series that the user won't see in the legend and won't be able to interact with.
I formatted the data label for the last (second) point of the scatter plot line to show the blue background and white numerals as in your example.
I set a marker on the last (second) point of the scatter plot line with a diamond shape. Together with the data label settings, this gives you the marker example you showed above. Now, there is a shape: 'callout' option for data labels, but the carats only point up or down for this kind of series.
I updated your mouseOver event to update the value of the scatter plot line, rather than adding and removing plot lines.
Here's the proof-of-concept fiddle: http://jsfiddle.net/brightmatrix/tzu3khp1/. You can also see a screenshot of the result below.
I hope all of this information is helpful for you. Please let me know if you have any questions; I'll be glad to update this answer to elaborate.
This a sample in highcharts for what exactly i need to create. The issue i am facing is the blue color should be in the area chart series, but highchart is applying the color at the top (outside the series). I apologize if i am not able to explain the issue correctly.
This happens when i use reversed: true, in yAxis.
Please help or let me know if you need me to explain the issue in different words.
When you reverse the axis, the data reverses as well, to match.
I would probably do this by using negative values as the axis min/max, and the data points.
Then, in the axis label formatter, return the absolute value (removing the '-').
labels: {
formatter: function() {
return Math.abs(this.value);
}
}
You can use the same formatting method to fix the tool tips, data labels, and anything else that might need it.

I have an issue with a HighCharts pie I've created. Sometimes the tooltip text overlaps with the legend, so I had to increase the legend's y property. However, this is causing parts of the legend (it's horizontal with 4 rows) to become partially hidden. I've tried adjusting the height property of the container, as well as a bunch of other properties, but the problem never goes away...
Here's how it looks like:

Any help is much appreciated.
If you are fine with pagination in legend then fix the height of the legend with maxHeight.
if the legend overflows, then pagination appears automatically.
legend: {
maxHeight: 30,
}
here is a working fiddle for pagination http://jsfiddle.net/cEcRz/
hope this is what you are looking for.
You can use pagination but in exporting add custom options to the legend like here:
http://jsfiddle.net/cEcRz/1/
exporting:{
chartOptions:{
legend:{
layout: 'horizontal'
}
}
},
Obviosuly you need to adapt other parameters like size etc.
With Highcharts 3.0 it is possible to create charts with type 'bubble', whereas prior to 3.0 it was necessary to use a 'scatter' chart and modify marker size to make bubble charts. The nice thing about the old way is you had complete control over the visible pixel radius of each bubble--the new bubble charts automatically resize the bubbles so they are sized relative to each other. Is there any way to turn off this behavior or set bubble radius manually?
I am having a hard time seeing how a bubble chart, where the bubbles are not sized relative to each other, would be of any use.
You should be able to use the minSize and maxSize options, however, to control them the way that you need to:
bubble: {
minSize:2,
maxSize:50
}
{{edit:
I don't see them in the docs either, actually. But you can see an example here: http://jsfiddle.net/fXzke/13/ use either number as pixel value, or string with percent of chart height
}}
I found that adding an "empty" bubble to the series helps keep the size of all bubbles in the chart relative to each other:
name: '',
data: [{x:0,y:0,z:0}],
showInLegend: false,
color: 'transparent',
enableMouseTracking: false
Here's a sample on JSFiddle: http://jsfiddle.net/9bebT/2/. The legend, color, and mouse tracking variables each help keep the item in the series but otherwise invisible to the user. If you simply remove the empty bubble or set its visibility to "false," the chart doesn't register the empty bubble's z axis (diameter) as the minSize.
As you can see from the attached image, my x-axis categories are getting bunched together in the middle. How can I configure highcharts to take up more of the x-axis? Note: The chart size is dynamic, it grows and shrinks based on the overall browser size and split-panels within the app. So explicit computation of the point-width is not an option (I expect highcharts to do the work for me).
Note: The picture is vertically cropped.
The chart options I'm using are:
highchart.setAnimation(false);
Legend legend = new Legend();
legend.setEnabled(false);
highchart.setLegend(legend);
highchart.getXAxis().setCategories(result.getAxisXCategories().toArray(new String[] {}));
highchart.setType(Series.Type.COLUMN);
ColumnPlotOptions options = new ColumnPlotOptions();
options.setStacking(Stacking.NORMAL);
options.setGroupPadding(0);
options.setAnimation(true);
highchart.setColumnPlotOptions(options);
In other words, legend is turned off and column plot options is set to zero group-padding.
UPDATE: Here is a JSFiddle showing the same issue
For others who run into the same issue, the solution is to set the pointRange option of the ColumnPlotOptions. In JSON this looks like:
"plotOptions": {
"column": {
"stacking": "normal",
pointRange: 1,
"groupPadding": 0
}
}
In GWT-Highcharts, you don't actually have a specific API for pointRange. Therefore set a generic option like this:
ColumnPlotOptions options = new ColumnPlotOptions();
options.setOption("pointRange", 1.0);
...
You can try to set pointWidth() http://api.highcharts.com/highcharts#plotOptions.column.pointWidth
