1. 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.

3. Differentiate the "touch" and "touch and hold" gestures on mobile device

   I noticed that the out of box Highcharts tooltip behavior today is: On desktop, mouse hover will show the tooltip; On mobile device, touch on a chart series will show the tooltip.

   No we are having the following requirement for Highcharts tooltip on mobile device:

   1. Touch on the chart series will trigger an event, e.g: chart drilldown
   2. Touch and hold on the chart series will show the chart tooltip.

   Is that possible for Highcharts library to differentiate between "touch" and "touch and hold" gestures on mobile device?

   Thanks for writing. It would be like http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/samples/highcharts/3d/column-grouping/, except with a line chart instead of column.

8. 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;
   

   };

   We don’t have pagination currently, but you can add a scrollbar to the X axis: http://utils.highcharts.local/samples/#view/stock/yaxis/inverted-bar-scrollbar

12. 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"].

14. 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!

18. Activity gauge - gradient with animation

    Hi All,

    I'm making a dashboard using Activity Gauge (http://www.highcharts.com/demo/gauge-activity) to show data.
    I need to make it with gradient effect like darker to lighter which seems not possible with linear or radial gradient logically it seems not possible.
    some how I have written an script with the help of support guy but seems not perfect solution as it do not have good visualisation and performance on browsers (very slower to load) see my samples -
    http://jsfiddle.net/td2v4u4z/47/
    http://jsfiddle.net/td2v4u4z/48/
    http://jsfiddle.net/td2v4u4z/52/

    I need charts with more sharp lines and clean curves like http://www.highcharts.com/demo/gauge-activity

    Can any one suggest me the perfect solution for this or can implement in you libraries?

    Thanks in advance.

20. 3-d bubble chart, or 4-d bubble chart

    The 3-d scatter plot could be a bubble where the markers are based on a 4th dimension. Unlike the 3-d coloring of bubble charts, this would be a true 3-d bubble chart.

    And a custom marker, say a 3-d 5-point star

    https://assets.mypatentideas.com/images/fiddle/star.png

    would be a bonus.
