Tooltip to show and format additional custom data per point
Needing to show additional data beyond the x and y value when above each data point. And need alter how the data is displayed for each point before it is displayed.
Wanting to supply data for each point in a format like ['X-time','Y-value','POINT SPECIFIC LABEL A!'],['X-time','Y-value','POINT SPECIFIC LABEL B!']9 votesAny member of the point’s configuration object can be referenced directly in the tooltip: http://jsbin.com/IyahIVeC/4/
To allow custom properties in array form, you can set the pointMap series property like this:

Sort stacked columns by total
Then Pareto graphs would look great even as series are added and removed.

Post Charts to Facebook
It would be great to be able to post preview images of charts to Facebook, so that when a user shares a chart on Facebook, it shows an image instead of just a link.
36 votesPosting a chart to Facebook would mean that we ad a backend to store the chart and to communicate with Facebook. Highcharts JS is a client side charting library, so this goes beyond its reach. It is up to the implementer to provide a backend for it.
Highcharts Cloud, however, has this capability. See http://cloud.highcharts.com.

Add the option of using a flash based SVG viewer
To speed up drawing of charts on IE <9 maybe add support for http://code.google.com/p/svgweb/ then IE<9 gets flash rendering if flash is available or VML if not.

Improve Column handling of negative values
Plotoptions on columns with negative values does not place itself correctly (offset seems to be added and not subtracted), also seems that formatter functions doesn't get run.
Also could you add a positiv and negative color list.

Add Custom Buttons
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.
31 votesHere’s how you do that: http://jsfiddle.net/highcharts/2F4pJ/.
It has always been around, but perhaps we need to document this more clearly.

Support for contextmenu event
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.111 votesI’ve tried to modify Joe’s patch into a plugin so that it can run without modifying Highcharts itself. The result can be seen at http://jsfiddle.net/highcharts/c42Ms/.
I didn’t have time right now to check across browsers, but I’m open for suggestions for improvements.

Programmatic line chart selection ( http://highslide.com/forum/viewtopic.php?f=9&t=8769 )
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:

Image fallback for non-javascript environments
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)

have options for pie charts with single values
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
