Add grouping in chart legend
Would be good to have grouping in legend so user can play with group as well as with legend item by clicking on it to show/hide items.
Click on group should work as click on each item in the group.Could look like in this picture: http://forum.highcharts.com/resources/image/4056

Optional function for yAxis to determine the column height based on its value
Though there is plotOptions.column.minPointLength property, it doesn't solve the problem completely.
Imagine there are columns which may have 0, 1, ... 1000 as values. These large values cause small values like 1 look like 0, i.e. no column is drawn.
By setting the plotOptions.column.minPointLength property to 3, causes the 0-value columns to be displayed as well.
All I want is to display the non-zero values to indicate to a user that there are some very small values.

Tooltip data interpolation
If I've got a sparse dataset (e.g. to save space, duplicate data points are omitted), a line graph still represents the data accurately, however the tooltip only appears over the actual data points.
Would it be possible for the tooltip to interpolate the data at the mouse pointer's position so as to show a value whether there's an actual data point there or not?

Natively support linked series to 'act as one' when the series legend title is hovered over
When two or more series are linked, only the first series (the one with the 'id') gets selected when the linked series legend entry os hovered over.
The other series linked to the first series are dimmed like all other (ie. non linked) series.
It would be nice if by setting a flag, each linked series would act the same as the first series when hovering on the legend entry.
See this for an example of what I mean:
https://jsfiddle.net/daniel_s/1hL6saxn/The above proposed solution is overly complex and convoluted, a native solution would be much cleaner.

Add census tracts and block groups to map collection
U.S. Census geographies are a widely used geography and I would love to see you add these as standard basemaps in your map collection archive. Although we can add them as custom geojson it would be nice to have them available standard. I am also happy to help with converting those geographies to SVG, JSON, and Javascript for upload in to the map collection.

add a `dashStyle` that can show the direction the line is going
When showing a line on scatter chart it can be hard to tell where the line started and where it ended.
Having a dashStyle option that was similar to plotOptions.scatter.dashStyle = 'dot' except that instead of a dot it was a rotated triangle that pointed in the direction the line was going would be awesome.
I saw some hacks for turning the entire line into one long arrow but that isn't what I was looking for.
1 voteA possible way to do it is to use SVG markers, see http://jsfiddle.net/4qgy4rmh/1/.

Symmetric waterfall chart
In some applications there are naturally two data "faces" that must match, say supply and demand, with a finite, unequal number of producers and users. A standard waterfall chart can easily show the individual producer and total change in supply from one period to the next, but it would be of great value to see supply and demand changes directly compared.
One way is to imagine the Highcharts population pyramid chart using waterfall charts on either side, with a common x axis, but separate y axes. The sum of changes to demand would typically be equal to the negative sum…

overflow datalabel for column/bar
Like the propertie 'overflow' that is used by show/hide dataLabel when it's outside the plot area,
It will be usefull, create a overflow propertie for columns/bars (or more charts where is applicable), that permits to the user define if a Datalabel must be render or not when the datalabel is bigger than a column/bar (column spacing)

Add an option to set minimum height to legend.
I am setting the legend height dynamically according to the chart size.
So when the chart size is small, the legend gets very small and distorted.
Assigning minimum height to legend will help my cause.10 votes -
Make it possible to group and style individual legend items
Over time my legend has gotten really crowded and i would like to be able to first: group my items, and secondly: style them individually.

add an option to mark a map series ARIA hidden
The accessibility module does not give a way to specify a series should be ARIA hidden.
When you have a map with data and map-lines the screen reader reads the map lines after the data.
Details of the issue are here

Dynamically change the menu items of the Export menu
Add the ability to dynamically make changes to the MenuItems located in the chart.options.exporting.buttons.contextButton, without having to destroy/recreate the chart, similar to setTitle() and addSeries() ability to dynamically change the titles and data, respectively.
Currently, one can access the array of MenuItems, and one can make changes to the objects themselves, specifically the onclick() function; the function itself is updated.
However, the text/styling, which may also need to be updated, is NOT reflected in the chart unless you destroy and recreate the chart.
Please add some function, perhaps that may accept an array of menuItem objects, that will re-render just…

Add a more detailed map for China.
I would like to request a more detailed map for China. Current map is at provincial level, which is fine for general purposes. But for some finer analyses, a city level resolution is very much desirable.
