Include options to set up custom buttons with call-backs to perform certain functionality.

For example, I would love to be able to have a button next to the current print and export buttons that would be used for help/information about the chart.

Please add support for contextmenu event handlers, or mousedown/mouseup/click events which are captured, to be able to prevent default browser right-click popup menu.
It would be useful to have an ability to show custom menu on different parts of chart (slice/series/point/legend etc.) with according info respectively.

Zoomable chart - Chart reset by double click to top of chart.

Allow programmatic selection of a line/lines on a line chart, to allow them to be made visibly distinctive from other lines. (Use different formatting).

Discussion as to why it is required is here:

I imagine this would be something similar to Google Static Maps, where a chart would be displayed via an img tag. This would be useful as a fallback for browsers with JavaScript disabled, or in dynamically created downloadable documents (like PDFs)

When a pie chart has only one item, a white line appears (the border). This is easily fixed by specifying a borderWidth of 0. But on hover, the line reappears. It'd be nice to be able to disable that border on hover as well

It would be great if you added support for drawing confidence bars so one could make something like this: http://listening-tests.hydrogenaudio.org/sebastian/mp3-128-1/results.png

Animation of Area charts does not work in v2.1.1.

See: https://github.com/highslide-software/highcharts.com/issues/issue/169/#comment_631931

Create datagrid but vscroll move fields move Hscroll move Field lock

For example test tubes graduated with different fill liquids and quantity, or any other shape, this is helpful for formulas inventory

If define global.lineargradient, then switch lineargradient on. Also I hope highcharts has it own set of default colorscheme for gradient which I don't need to worry about.

I propose to remove div after closure (div created by clickable points).

In highslide-full.min.js:2932 to afterClose function i've added:
hs.expanders[this.key].content.parentNode.parentNode.removeChild(hs.expanders[this.key].content.parentNode);

this solutin will be very helpfull

Please, consider these two features :
- allows to set the radius proportional to a third data point variable (z),
- allows to connect some markers by line segments (this will illustrate the fact a given value is related to another one)

It would be most useful to restore the "target" option in the "credits" configuration so that when the user clicks on the credit text (usually in the lower right angle of the graph), the link can be opened in a new page instead of the current one.

The dynamic SVG plots could be replaced by a static image of the plots, similar to how the exported PNG looks. The choice between dynamic and static could be made at runtime based on the size of the dataset.

I'm generating scatter plots based on data from a database. The plots looks great, however the performance gets to be a probably when the plot has more than 1000 points.

Allow setting of shape-rendering attribute in order to enable speed optimising.

Code modification example:

SVGRenderer.prototype = {

/**

 * Initialize the SVGRenderer

 * @param {Object} container

 * @param {Number} width

 * @param {Number} height

 */

init: function(container, width, height) {

    var box = doc.createElementNS(&#39;<a rel="nofollow noreferrer" href="http://www.w3.org/2000/svg&#39;">http://www.w3.org/2000/svg&#39;</a>, &#39;svg&#39;),

        loc = location;

    attr(box, {

        width: width,

        height: height, 

        &#39;shape-rendering&#39;: &#39;crispEdges&#39;, //suggest to add this by config

Currently formatters can only return strings that then get wrapped in a svg text element.

It would be great if formatters could optionally return svg source themselves (or even have access to the svg renderer) so that it would be possible / easier to implement custom modifications to the way data labels and legend items are rendered.

I'd like to see a PowerPoint export option.

The Highcharts chart would have to be a "chart object" on the PowerPoint slide, meaning you could click on the chart in the slide to change properties.

I'd be willing to pay more/extra for an export module that had this capability.
