allow to modify navigator event handlers
Right now navigator event handlers are hidden, and can't be wrapped. In order to modify them, you have to wrap Scroller.init, and re-register events after modyfing them. So basically you can't redefine one event, you have to redefine all 3 of them, because they share scoped variables (dragOffset, hasDragged).
Please change it. Something like array/map of events, which can be changed before calling Scroller.init would be awesome.1 vote -

Dynamically modify the menu items of the context menu
We need to dynamically modify the property of the menu items, such as to disable certain menu items and make then grey out. I saw the same idea was posted before.
I don't know how to do it or any workaround. Someone mentioned to set chart["cache-highcharts-contextmenu"] to null to force redraw. Since I am new to the Hightchart, it would be nice to post a simple example.

mapNavigation.buttons y position
There is no "y" property for mapNavigation.buttons, so it is not possible to adjust precisely y position.

Custom approximation function
I would like to have an approximation function in which we can access all the information from the points instead of just the y values. This allows me to not only decide how to group but also an ability to capture information from all the points into the grouped point.
24 votesAs of the next release, we have implemented a hook for getting the raw data for data grouping. See http://jsfiddle.net/xfLLr03a/.

DataLabels rotation for treemap
When sliceanddice in treemap, boxes may be taller than wide and datalabel may be larger than boxe.
Here is a small modification that rotates datalabels in this case
drawDataLabels: function () {
var series = this,
points = series.points,
options,
level,
dataLabelsGroup = this.dataLabelsGroup,
dataLabels;
each(points, function (point) {
if (point.node.isVisible) {
level = series.levelMap[point.level];
if (!point.isLeaf || level) {
options = undefined;
// If not a leaf, then label should be disabled as default
if (!point.isLeaf) {
options = {enabled: false};
}
if (level) {
dataLabels = level.dataLabels;
if (dataLabels) {
options = merge(options, dataLabels);
series._hasPointLabels = true;

Stack multiple charts on top of each other
I've recently run into a case where I need to show a small pie chart on top of another graph chart. I had to use css to put the pie chart on top of the graph. So I guess we might want to have some option for stacking the charts?

The graph looks totally broken when inside a RTL container (such as <DIV style="direction:rtl">….</DIV>)
The graph looks totally broken when inside a RTL container (such as <DIV style="direction:rtl">….</DIV>)
The line tooltips text are outside it's bubble, the legend looks totally out of order, the pie lines has strange offset and more…This applies to all 4.1.x versions, including the latest 4.1.5 version, however, it looks OK on previous versions (4.0.x or earlier) which means – it's a new bug introduce only lately in 4.1.x versions.

Tooltips should show the serie symbol
Right now the tooltips have this default for the pointFormat option:
<span style="color:{series.color}">\u25CF</span> {series.name}: <b>{point.y}</b><br/>.
\u25CF is always a circle, instead of matching the serie symbol, like it does in the legend.
This is very important for charts with many series, when using a shared tooltip. Especially if you are color blind.

Label at last data point
It would be nice to show a label between 2 ticks at the x position of the last data point.
This way you can see the most recent entry more clearly, and without having to hover over the data point.12 votesSee http://jsfiddle.net/highcharts/mAJtj/ for a possible solution using data labels.

Add option to render in HTML5 canvas for large data sets
SVG is too slow for very large data sets as you pointed out in this helpful example: http://www.highcharts.com/demo/heatmap-canvas
I realize that highcharts has moved to using SVG, but it would provide the user more flexibility if they could choose the renderer (SVG or canvas). Extending highcharts to use canvas.
In my usage case, I have anywhere from 3,000 to 30,000 data points in my map. Switching to canvas made the map render over twice as fast (and is much more responsive)...but it has been a lot of effort to get the desired features working.(BTW, I believe Zingcharts has this…

Custom date parsing format
It would be really nice to have a custom date format option implemented in HighCharts / HighStock, so that it could parse dates from different sources.
In case it's useful, here's an example of how such feature is implemented in a couple of other JS popular libraries:
• http://momentjs.com/docs/#/parsing/
• http://c3js.org/reference.html (check "data-xFormat")Cheers!
6 votesHighcharts by default requires integers in form of milliseconds since the Unix Epoch.
When using the data module however, you can add parsers either as a few predefined formats, or as a dateParser callback. See http://api.highcharts.com/highcharts#data.dateFormat.

Require scrolling feature
If I tend to display huge volume of data, chart GUI is not stretching to accomodate all contents, instead it reduces their dimensions to incorporate them within given area. This makes chart unreadable, also leads to overlapping of data during display. It will be great if chart length grows horizontally on more data and provides a scroll bar
