1. Hit-test point in map

   For Highmaps, we should have a method to find which map area a point lays within. Useful for building heatmaps.

2. 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;
   options
   }
   }
   options = merge(options, point.options.dataLabels);
   point.dlOptions = options;
   } else {
   if((point.shapeArgs.height/point.shapeArgs.width) > 1) { //MMK Modif pour gestion orientation text quand hauteur > largeur
   point.dlOptions = {rotation:-90,align:"center"}; //MMK Modif rotation text et centrage
   } else { //MMK Modif
   delete point.dlOptions; //Ligne strandard
   
   } //MMK Modif
   }
   }
   });
   this.dataLabelsGroup = this.group;
   Series.prototype.drawDataLabels.call(this);
   this.dataLabelsGroup = dataLabelsGroup;
   },

3. 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?

5. 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.

6. Internationalization involving rtl languages

   A suggestion I would make in the Internationalization context would be an overall rtl chart command which would call into action a group of these piecemeal xAxis reversals, navigator xAxis reversal, yAxis oppositeness, rangeSelector positioning, and input positioning. In the same vein as setting rtl in your <body> tag. Perhaps the chart should even take a hint from the enclosing div’s direction tag in lieu of requiring this explicitly. Now, that would be a clean rtl interface!

   Positioning of the rangeSelector buttons: they should move and reverse so that they begin on the right side and progress leftward.

   Also, the input boxes should reverse their positioning.

7. Manage multiple pie series dinamically

   Would love highcharts to be smart-enough to be able to manage multiple pie series in a smart/dynamic way

   This would include

   1. being able to handle multiple series on pies this should be handled automagically, same way other type of charts does (bars, columns, ...)

   this would include rendering the diferent series in the given container, making its representation fluid.
   currently the JS programmer needs to specify the centre of the pie, and the size of it, being aware of the given space, leading to some calculations that are difficult to handle when leading with a dynamic number of data/series.

   parametrization would be appreciated, such as specifying max number of series per row, for example, or margins, paddings etc.

   1. highcharts should also handle the names of each series, as the title for each one.
      this should be done automatically, without the need of specifiyng any events.
      right now its quite tricky because of 1. point

   2. highcharts should handle the multiple legends that are the same for every serie of the pie graph.
      this should be done automatically, without the need of specifying any renderer function events

   Same functionality other libraries have, such as JPivot
   http://www.webdetails.pt/ctools/ccc/#type=pie&anchor=small-multiple-pies

8. 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.

    It’s a good idea, Iit would require that we either are able to send images directly from the browser memory to the social media APIs, or that the export server passes the images to the APIs.

13. Allow chart to determine/set auto-height/width.

    See here: http://forum.highcharts.com/post115029.html

    This would add a chart width/height setting of "auto". For bar charts, the auto height uses the point width and padding options to determine the "correct" height of the plot box, instead of using the size of the container. For column charts, the chart would grow/shrink horizontally to fit all columns.

    We experimented with this in http://jsfiddle.net/gh/get/jquery/3.1.1/highcharts/highcharts/tree/samples/highcharts/studies/axis-staticscale/

14. 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.

15. Initial label autoRotation value

    I am using x axis label autoRotation, but I want to specify an initial
    rotation other than 0. I other words, when I want all labels to initially
    draw at -30, but if the user shrinks the chart width, then I want auto
    rotation to go to -45, then -60, etc, but rotation at a minimum should be
    no less than -30

16. Clickable labels and hover for bar and column chart.

    Use a bar / column chart to map companies vs their annual revenue. Click on the company name in the bar chart label can give me more information about the company etc. Having a hover target on the label can provide me more context.

    Basically we want click target recognition as well as hover targets for the bar and column labels on the bar and column charts

    Legend not to interfere with swipe on tablets to scroll the screen

    In a tablet, when I try to swipe the screen to scroll down/up, I have to avoid touching the legends. Otherwise, the screen won't scroll, instead, one of the legends would receive the touch event. Is it possible to make a change such that swipe on the legends can scroll the screen, instead of toggling the legends?
