When clicking on the top level of the treemap object, there should be nice zooming effect. Like this one https://bost.ocks.org/mike/treemap/1 vote
We do it too, but it depends on the animationLimit setting. See http://jsfiddle.net/highcharts/axph4j2h/.

Sankey diagrams are planned for Highcharts 6. Here’s an early exploration into the subject: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/samples/highcharts/studies/sankey-diagram/.
Currently Rangeselector position is fixed at top. It should be possible to provide custom position for rangeselector230 votes
It is possible to set rangeSelector to float and position it inside of the chart. The option is available since Highstock version 6.0.0.

I want to plot a polar chart on top of a map to show the air pollution concentration and the wind direction on the map. I prefer it to be Google map but any satellite map will do. Is it possible ?3 votes
Yes, basically you just need to place a div on top of the Google map, then add the chart to the div.
Users these days are very used to zooming and panning maps, in a way where panning does not reset zoom level. We find our users wanting to explore the rest of a chart after selecting the zoom level, but the current interface forces them to reset zoom, pick another region and zoom again.
A zoom-and-pan user experience would take highcharts to the next level - use the metaphor of Google Maps.3 votes
Thanks for your suggestion, but this is already supported through the panKey option. See http://api.highcharts.com/highcharts#chart.panKey. Does this work well for you?
Since Highcharts version 7.0.0 3D Cylinder series type is available.
There are 3 reasons for wanting this:
1 To enable users to add/remove points using the legend
2 Data labels don't fit in the smaller data points. If you have several smaller data points the labels either overlap or get suppressed
3 When a treemap and other chart types are presented side by side, they should look the same as much as possible. Having a legend on all chart types does just that.11 votes
Thanks for your suggestion! I did some refactoring to allow this functionality with more series types than just pie and its derivatives. For example it makes sense for columns with colorByPoint also.

The official Highcharts supported wrapper for React
Recently I came across the requirement of implementing a column chart with individual widths of each column. This allows us to express two informations within one bar, I know pretty well about the discussions of "is this still readable" bit to advanced controllers it is.
I think it would be a great feature to include this second dimension to bar and column charts in order to create so called "multi dimensional bar charts".
Thanx for checking this feature request,
The variwide chart type is available since Highcharts version 6.0.0.
When multiple series are used and if the flags are overlapping it should be moved a bit to prevent overlapping.Currenyly the stackWidth option allows it for only one series .What if i have connected series like a part dotted and part solid series. I wont be able to use stack distance in this case. So require something to push the y values a bit if they are overlapping even if on different series.97 votes
The flags series has horizontal overlapping enabled by default since Highstock version 6.0.4.

I plan to implement this using the spline mode + manually plotting the distribution (100 points), but it would more convenient as a built in type. Actually, a number of options for showing data distribution / percentile would be lovely! :)68 votes
The bell curve chart type has been added to Highcharts in version 6.0.0
I found tooltip is always for points in polygon but it will be good if we can have tooltip for polygon so that more and more information can be fetched for the covered area.1 vote
You can add whatever information you like in the tooltip format or formatter settings.
As a keyboard user I would like to be able to activate features which are currently only available to mouse users.
For example I would like to tab to a line plot data point to expose the tooltip balloons. I would also like to be able to use my keyboard to activate the links which are currently mouse click only.10 votes
This is now implemented in the Accessibility module: http://www.highcharts.com/docs/chart-concepts/accessibility
I would like to get the extremes on scroll of the chart. With this I want to show the plotted values of the visible chart.1 vote
You can use the X axis setExtremes event, and check for e.trigger === ‘navigator’. See http://jsfiddle.net/highcharts/un3fLbqr/.
Cant get same line chart in term of size on downloaded pdf and web page, 2) Cant get some solution for tapping the line points means over af
I used High Chart in one my project [please see image attached linechart with small line and ponter.png] here having line charts and points means tab on each point. Now I added functionality like download this in 'pdf' form for that I used 'mpdf' lib in PHP. If I used another chart like raphel js then chart look same as that of in web page and pdf. However I used hight chart found one issue that its come on pdf but line are too much broad(big sizelline) as compare to web page[see image attached linechart.png and strain_detail.pdf ]. I think there must be some solution for that
Means there are two issues
1) Cant get same line chart in term of size on downloaded pdf and web page,
2) Cant get some solution for tapping the line points means over affect in pdf as of web page
If anything please let me know.
Hope Positive Response from you.

1. The wide line is probably the tracker object for your chart, probably the PDF library doesn’t support opacity correctly. Try disabling mouse tracking in the exported file like so: http://jsfiddle.net/highcharts/ztfj7ktd/.
2. The exported PDF does not support events.

I would like to use Highcharts to render such chart: http://alumni.media.mit.edu/~fviegas/projects/mountain/
Is this possible? So that data would tell from when to when a particular value is active, and then it would be stacked together in this way?2 votes
This is a stacked area chart. Each thin line (stratum) is represented by a series.
PS: If you have raw data for this, I can help you set up a sample.
I would like a new "mode" approximation that returns the most common element of an array when grouping data. Currently we have "average", "open", "low", "high", "close", "sum" and none of these work for me. So if the array is [1, 2, 3, 4, 4], I want "4" (most common), not "2.8" (average).
If the results are multi-modal [1, 1, 2, 2] or non-modal [1, 2, 3] then "open" is a good fallback.
I would also like this "mode" to be available in OHLC popups.3 votes
As you can see in the docs, the approximation can also be a callback function. This means you can create your own function that returns the most common element.
