Collision Detection for Data Labels
Implement collision detection algorithm that repositions overlapping data labels, with possible input parameters dictating a proportional distance to move labels away from each other, or directionality indicators.

Plot Band can be divided into sub Band
Plot Band can be divided into sub Band. If this feature is provide then it will be easy to define Sub band in a plot band. Just like a stack bar diagaram
1 voteDo you mean that a plot band on the X axis can be limited to a certain Y range?
A possible hack to achieve this would be to use a polygon series: http://jsfiddle.net/highcharts/2c97sc5r/

Position tick labels between ticks on a date-time x-axis
In a chart with data plotted on and datetime x-axia i would like to position tick labels between ticks rather than on ticks. An when i zoom they still appear in the center to the right of it's tick.
for example i have a tick on August 1st and another on September 1st and my date formate is MMM. I would like to see 'Aug' centered between the August 1st tick and the September 1st tick
7 votesThis would definately be a nice feature. I believe we would need two types of label placement on datetime axes. Interval labels would be placed between ticks. For example a month name. But if the interval spans two months, like August-September, the label would have to be placed on the 1st of August.

Bubble chart- Data label positioning at the bottom
As of now, If the bubble is near the x-axis, by default the data label is positioned on top of the bubble. Our requirement is to align within the plot area (above the x-axis) either to the left or right of the bubble.
Thanks In Advance

Provide support for creating HighCharts using Web Worker
Sometimes, creating and rendering charts hampers the performance of application. So, it is a smart idea to create and render chart using the web worker. For details visit: http://forum.highcharts.com/highstock-usage/does-highstock-library-work-with-web-worker-t35660/

xAxis tick labels overlapping handling
Hi,
Now we have automatic xAxis labels rotation or overlapping handling.
But1.When I generate xAxis labels by myself with tickPositions - then auto-positioning(overlap handling) is not working. Can you make labels autopositioning work for custom tickPositions please?
- One more approach - if custom labels overlap - then show '...'(or some other filler) but show full labels on zoom In.

Hiding empty columns
If you hide all bars in a column that is in the center of things, it will not be hidden currently. I suggest that this is made possible.

Support 3d line charts with multiple series
At the moment there is no support for 3d line charts with multiple series. Something like this

Include CSS for each example theme like grid.css
The CSS for each of the existing example themes should become part of the product download. Please see this forum post: https://forum.highcharts.com/post135634.html#p135634 t

Data labels with collision avoidance and connectors for scatter and bubble charts
Scatter and bubble charts do not seem to support collision avoidance for data labels. Along with collision avoidance, connectors that link the points to the data labels would be very helpful.
Thank you for the great library.
24 votesAs you can see from http://jsfiddle.net/highcharts/2cu52v0e/, there is currently collision avoidance.
It hides colliding data labels, but it doesn’t move them, and subsequently doesn’t add connectors.

Create some form of tree / node linking chart
Highcharts doesn't currently appear to have any tree / node linking chart types. A few examples would be:
- Dendograms: https://en.wikipedia.org/wiki/Dendrogram
- Hierarchical clustering: https://en.wikipedia.org/wiki/Hierarchical_clustering
- Minimum Spanning Tree: https://en.wikipedia.org/wiki/Minimum_spanning_tree
The above chart types vary in their purpose and how they are constructed. But this request is simply to have some form of tree / node linking chart capabilities in highcharts.
Once it becomes possible to chart a basic tree or hierarchy structure, it may be easier to extend functionality to create further chart types along the same thinking.
Plot.ly currently offers both dendrogram's and tree plots within their python API. But of…
38 votesThanks for writing! We have support for treemaps in Highcharts 4, and we’re considering adding the related hyperbolic tree maps after the release of HC5.

Beeswarm plot (aka. strip chart / dot plot)
It would be great to have a simple dot plot in HighCharts. Categorical data with a single value, displayed with sideways jitter to prevent dots overlapping. The advantage of this plot is that it is great at showing distributions. It's also simple to interpret and good with large numbers of data points.
There are several R packages that do this (beeswarm being the main one). See http://www.cbs.dtu.dk/~eklund/beeswarm/
Bonus points for dealing with overlapping plots intelligently (see beewarm package 'corral' options). Perhaps automatic point sizing?

Circular Treemap charts
Instead of having Treemap as groups of rectangles, we can have it as group of circles.
Something like this:

data module for database tables
data module was a great addition. have been using that pretty much everytime i can covert my data to csv.
but having database module to load data from one table would be just awesome.
116 votesMaking backends for data bases is complex, as it covers a wide range of different databases and languages. A project like this would have to start with only a few of the most popular backends. We are currently considering a “connectivity” project that will do some of this.

Highmaps: Map Collection does not have world map with disputed areas
The world map provided in Map Collection does not show disputed areas of countries. It would be really helpful if the disputed area of Jammu & Kashmir state is shown as part of India in world.json

Add stacking range in column charts
I am creating a column chart with Highcharts and I want to stack the values by time. So the xAxis is of type datetime. If the date sent is identical then the stacking is working right but if there is a second of difference, then it's not stacking well and the user experience is weird. A possible solution would be to add a stack range in order to group the similar date values. You can find my Stackoverflow question here with an image and a fiddle: http://stackoverflow.com/questions/39788944/highcharts-column-chart-stacked-not-showing-all-the-values

Title and Chartnames To Be Selectable with mouse .Would You Please Add this opprtunity?
I can't select the title and the chart categories . In some situations I need to select and copy those strings . Would You Please Add this opportunity ASAP?
34 votesHi, this feature is prevented in two places, because there were problems with text being selected when trying to zoom in. See https://github.com/highcharts/highcharts/issues/3224.
If you want to enable text selection, there are two lines where the event handling is prevented. If you comment out both these lines, your users can select text:
- https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L756
- https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L813
- Don't see your idea?
