Allow labels on datetime axis to be modified prior to formatting
Using local time for a datetime axis is usually a bad idea, because when daylight saving is introduced parts of the x-axis would overlap and other parts would have gaps. So data points on the axis are best plotted using UTC. However, it can then be useful to label them in local time. It might also be that the local time required is different to the PC local time, if you are supporting a Italian user from the UK, for example. These requirements could easily be supported by modifying the dateFormat function to call a user-defined adjustment function that could…

multiple points for same date w/ average
The idea is to have it so on a line graph, I can have more than one point for a date (or x-axis point) and the line chart code will average it when creating the line. This is useful for line charts that have multiple observations for a specific date.

Process Control Chart
Room for easy visibility for Western Electric rules which attempt to distinguish unnatural patterns from natural patterns.
For example, adding a remark at a point which two out of three consecutive points fall beyond the 2σ limit, on the same side of the centerline.
Another example would be: Five consecutive points fall on the same side of the centerline (average)

Area Fill: multiple fill levels
Currently area is filled above and below some threshold level. It'd be nice, if two separate levels could be specified: top and bottom with are filled above top and below bottom. Even color could be specified for each fill: top-color, bottom-color.

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:

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.
