2. 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"].

3. 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;
   

   };

7. Shared Tooltip (Against Y axis)

   I'd like to be able to have a shared tool-tip use the y-axis value to group by and show the x-axis values shared for that y-value. This comes up when depicting a percentile chart with 1-100th percentile on the y-axis (as is traditional) . I could not find a way to do it.

14. Dynamically arrange column chart high to low or low to high

    It is good to have the functionality to auto arrange series data in high to low or low to a high value so graph looks understandable when especially there are too many bar/columns. Also, It would be a good idea to short in ascending/descending order by the group.

    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.

17. Waterfall Chart with Pre-Aggregated Interim / Final Balance

    Currently the Waterfall Chart can create Interim Balances, but those are calculated as part of the chart.
    In case the actual data set already provides those interim balances and Final Balances, those can not be leveraged because as soon as the Interim / Final Balance flag is set, the actual data value is being ignored.
    There should be an option to decide if an existing entry from the data set should be visually represented as Interim / Final Balance.

18. render the dataClasses legend like the gradient legend

    Check out the legend on they NYFed site

    https://www.newyorkfed.org/data-and-statistics/data-visualization/community-credit-profiles#inclusion

    The dataClasses are joined together and the arrow pointer points to where in the data class a specific point lives.

    I have implemented similar code but it would be nice if it was an option by default.

19. Make tooltip text selectable + suitable html generator for html tooltips + continue to show tooltip until tooltip-are-mouse-leave event

    As for me tooltip functionality is quite restrictive and not very convenient for now (5.0.14).
    1. I cannot select text on tooltip.
    I found some examples where we just copy original tooltip, show it and then do e.preventPropagation for mouseDown, mouseup and mousemove events on tooltip area.
    but maybe it can be done by some parameters?

    1. Suitable html generator for html tooltip - it is inconvenient to generate html with concatenation of string na respective params. And hard to apply event listeners on elements of html-tooltip. Maybe some helper functions to add?

    2. continue to show tooltip until tooltip-are-mouse-leave event - actually it can be done with e.preventPropagation for mouseDown, mouseup and mousemove events on tooltip area.

    What do you think? It will allow:
    1. Use html tooltips in very quick and convenient way
    2. Make tooltips dymanic generation with eventListeners, buttons, changes its view in action (Show small tooltip with 'more' button to increase it, for example)
    3. Make it possible to copy text on tolltip

    Actually it seems like you are looking for something more than a simple popover text display, especially since you mention buttons and events etc, I think it would be better for you to go with a completely custom implementation. You can hook up to point events to get started: http://jsfiddle.net/highcharts/rsvkc3x3/

20. 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 of changes to supply, the difference being stock changes or measurement errors. The offset from the common origo x would indicate the overall change in supply/demand.

    I recognize that this is not a standard chart in any typical charts library, but I would hope that the idea could be of general interest and possibly add another unique feature to Highcharts. Since it conceptually uses the existing population and waterfall charts, I also hope it could be short way to implementing it, whether in horizontal or vertical format.
