1. add events to axis labels

   there should be standard events like mouseOut, mouseOver, click , etc. available for axis labels. currently it is possible to do it through custom events plugin, but it is not compatible with latest highcharts

   The Pointer object has a nice utility that you can use to detect whether a certain class is clicked: http://jsfiddle.net/qcehvqqk/

2. SVG marker symbol sizing by height and width instead of radius

   I have a project where I needed to add mean diamonds to a boxplot, and I have a working prototype where the height and width of the marker symbol are used instead of the radius. The marker height needs to stretch or shrink based on a data value instead of being fixed by a radius value. Below is a shim that I wrote that modifies the Series markerAttribs function. Can you take a look at this function and find a way to integrate it into a future release?
   Thanks,
   Jeremy

   //Taken (and altered) from highcharts.src.js (v5.0.7) line 17497
   Highcharts.Series.prototype.markerAttribs = function (point, state) {
   var seriesMarkerOptions = this.options.marker,
   seriesStateOptions,
   pointMarkerOptions = point.marker || {},
   pointStateOptions,
   radius = Highcharts.pick(pointMarkerOptions.radius, seriesMarkerOptions.radius),
   height = Highcharts.pick(pointMarkerOptions.height, seriesMarkerOptions.height),
   width = Highcharts.pick(pointMarkerOptions.width, seriesMarkerOptions.width),
   attribs;

   // Handle hover and select states
   if (state) {
       seriesStateOptions = seriesMarkerOptions.states[state];
       pointStateOptions = pointMarkerOptions.states &&
           pointMarkerOptions.states[state];
   
       radius = Highcharts.pick(
           pointStateOptions && pointStateOptions.radius,
           seriesStateOptions && seriesStateOptions.radius,
           radius + (seriesStateOptions && seriesStateOptions.radiusPlus || 0)
       );
   }
   
   if (point.hasImage) {
       radius = 0; // and subsequently width and height is not set
   }
   
   attribs = {
       x: Math.floor(point.plotX) - radius, // Math.floor for #1843
       y: point.plotY - radius
   };
   
   //use height and width for SVG instead of radius
   if (!point.hasImage && height && width) {
       attribs.x = Math.floor(point.plotX) - width/2;
       attribs.y = point.plotY - height/2;
       attribs.width = width;
       attribs.height = height;
   }
   else if (radius) {
       attribs.width = attribs.height = 2 * radius;
   }
   
   return attribs;
   

   };

4. Provision to add dataLabels (median, min, max) in boxplot

   There must be a provision to add labels for max, min, median in the plot itself apart from the hover. While taking print, it would be great of the labels are printed for ease of use.

5. Horizontal Legend Paging

   The legend paging that was implemented works well for vertical legends, but not for horizontal legends. In the case where there are many plots on the same chart, the paging buttons take up too much vertical space on the chart, they should be floated to the left or to the right, or the legend should become a "scrollable" object to avoid this issue.

   P.S. Another issue is that the legend has some clipping issues if there are more than 2 or 3 pages.

   This can all be seen here:

6. ignore series for axis scaling

   like to be able to tie a series to an axis for display but have it ignored for scaling as long as there is another series available to that axis for scaling.

   Series : [ ignoreForScaling : Default false] or maybe
   Series : xAxis|yAxis : [ignoreForScaling :Default false]

7. Dynamic description

   Currently the chart.description property accepts a string.

   If there was a chart.descriptionFormatter or similar property that expected a function. If this function was passed the chart data then it would be fairly trivial to make dynamic descriptions.

   This would be fantastic for accessibility too in dynamic cases such as stock charts. Knowing that it is a line chart the developer could easily write a function that could return something along the lines of:

   "This is a line chart showing Acme Co's stock price between {startDate} and {endDate}. In that period the price has [risen to|fallen to|remained stable at] ${price}. Volatility in the same period has been measured at {v}"

   By making it generic it can support all chart types and it puts the onus on the developer but allowing for flexibility.

10. Funnel with fixed height

    It would be nice to have an option for the funnel to set a fixed height for each row.
    I'm thinking of an separate array with percents. So you can make a upside down pyramid like this:
    http://www.searchenginejournal.com/wp-content/uploads/2013/03/image00113.png

    So you set a height for the chart and the config would be [25,25,25,25]

13. Allow gauge to take negative/positive value, extending from a zero position

    http://jsfiddle.net/j99skchd/
    This example displays a gauge from -4 to +4. The series data value of 0.5 would ideally make the gauge colour the range from 0 to 0.5.
    Correspondingly, a series data value of -0.5 would make the gauge colour the range from -0.5 to 0 (and in the example we would make that a green range).

15. Make categories a valid JSON object.

    Make categories a valid JSON object. Much easier to use JSON option SQL Server 2016. See functionality SQL Server 2016 for JSON. I want to set categories in Highcharts like so:

    categories: [{"name":"apples"},{"name":"bananas"},{"name":"kiwis"}]

    Or something else for 'name'. Now I have to use a trick with XML and STUFF to get it like ["apples", "bananas","kiwis"].

20. Release SVG to Map as a independent tool

    Today we have a tool in http://www.highcharts.com/studies/map-from-svg.htm that actually works...

    But, that tool does not work as a "independent" tool, running in NodeJS, for example, and because of that it is simply not usable to convert maps in mass, passing multiple files and converting everything with just one command.

    Please, release that tool as a independent NodeJS tool, installable via NPM!
