Display negative percentages for Stacked Bars/Columns
When I create a stacked bar or column chart with the stacking set to "Percent", the negative percentages should be shown in a negative axis.
As shown here in Excel: http://i.imgur.com/R3RboAe.png

Bubble maps plotted by longitude/latitude - basically a hybrid between mappoints and mapbubbles.
For example, plotting a map of Uganda using the dataset below where the size of the bubble is determined by the datavalue, and the position of the bubble is determined by longitude/latitude.

Implement Option in Highmaps to adjust mouse-wheel zoom sensivity
I think the current zoom-in by mousewheel is way too fast and should be slower or controllable by the creator of the chart.

Disable Element like RangeSelector Dynamically
It can be interesting to disable Element like RangeSelector dynamically. Like when you export a chart. We can do something like:
chart.options.rangeSelector.enabled=false;
chart.update();
There is a method to hide element:

That I found on stackOverflow (http://stackoverflow.com/questions/25802472/how-to-hide-show-scrollbar-and-range-selector-of-highcharts-on-button-click)
But this is not very good, because the Element are hidden but if you hide the the navigator and you have a legend, the legend won't move for example9 votesEvery option in chart can now be dynamically updated via `chart.update(newOptions)` API.

Allow automatic scrollbar for responsive charts
There should be a feature where scroll appears or disappears when the div containing chart is resized. When the chart is big enough to fit into available space, the scrollbar should be hidden and when the chart container is resized (reflow called internally), the scrollbar should appear automatically to show the data points instead of making these data points smaller.

Add options for the placement of the data labels in pie charts
Options for the placement of the data labels in pies, such as connector lines pointing back to the slice. I've found a forum thread talking about this here : http://highslide.com/forum/viewtopic.php?f=9&t=5865&p=27996

When exporting charts don't show the hidden curves.
Eg : A user is given a chart with 5 series and has decided 2 of them they don't want to plot and disables them. When they export to either a file or printer the export needs to reflect those preferences.

Create Prototype Adapter
There is a third party prototype adapter at http://github.com/mnelson/Prototype-Highcharts-Adapter . It would be great to have this merged into Highcharts and officially supported, since new releases can break it.

Ability to skip a period of time but without gaps on xAxis
For stock chart I want an ability to skip a period of time but without gaps on xAxis.
This is a standard feature when displaying intraday data, otherwise chart has nasty gaps between days.7 votesIt’s possible to achieve using one of the options:
- xAxis.ordinal
- xAxis.breaks -
Offer a minimum width for the navigator scroller
I routinely work with charts that have hundreds or thousands of data points. In these cases, even a reasonably-sized window is relatively small compared to the overall window of data. When this happens, the scroller in the navigator becomes uselessly thin, often 1-2 pixels or even 0 pixels! (Yes, I've actually seen this.) Desktop operating systems solved this problem many years ago by enforcing a minimum width for the scroller. Is there a way for Highstock to do the same?
7 votesThis is implemented and will be released with the first maintenance. A new option, scrollbar.minWidth is added with a default value of 8.
See http://jsfiddle.net/highcharts/YdTpG/ for test case.

Custom abbreviated weekdays
There is already support for custom abbreviated months (shortMonths), but weekdays are still automatically abbreviated as the first three letters of the full name. This doesn't work for all langauges, e.g. for Finnish, where weekdays are abbreviated as the first two letters ("maanantai" -> "ma").
7 votesThanks for posting, this is implemented now. See https://github.com/highcharts/highcharts/issues/4871. It will be part of the next maintenance release.

Vertical line markers
I would like to add vertical line markers to mark for events which happened during the time-series data (like device reboot). Like flags from Highstock, just without any label associated and line going from top to bottom. With axis flags it is hard to precisely see when the event occurred when having multiple series plotted. And because the event is for multiple series all together, it is not reasonable to put them onto a particular series.

add useHTML to the x/yaxis categories like is done for tooltips
It would great if we could use some lite HTML in the x/yaxis category array in order to create a title and subtitle like display.
Categories = [
"<b>Title</b><br/>Subtitle"
]This does work and display in Firefox just fine, but crashes in Chrome. It does work in Chrome if you remove the <b> tag around the title. Still it would be nice to be able to use html here to provide some styling.

Using the navigator shouldn't cause changes in window size
Interacting with the navigator shouldn't cause the current window size to change. More details here: http://highslide.com/forum/viewtopic.php?f=12&t=16630
