Left Shift Last real time updating bar
There should be a function to left shift the bars in the viewing range. so that we can see some space available between the last bar ( which is updating real time) and right side border of the chart.
It is a standard feature available in all stock market software. Particularly if you see meta trader MT4, chart shift feature is available in chart menu.
This is nice feature to have in the charts.

Tooltip data interpolation
If I've got a sparse dataset (e.g. to save space, duplicate data points are omitted), a line graph still represents the data accurately, however the tooltip only appears over the actual data points.
Would it be possible for the tooltip to interpolate the data at the mouse pointer's position so as to show a value whether there's an actual data point there or not?

Dynamically change the menu items of the Export menu
Add the ability to dynamically make changes to the MenuItems located in the chart.options.exporting.buttons.contextButton, without having to destroy/recreate the chart, similar to setTitle() and addSeries() ability to dynamically change the titles and data, respectively.
Currently, one can access the array of MenuItems, and one can make changes to the objects themselves, specifically the onclick() function; the function itself is updated.
However, the text/styling, which may also need to be updated, is NOT reflected in the chart unless you destroy and recreate the chart.
Please add some function, perhaps that may accept an array of menuItem objects, that will re-render just…

Add rowrange chart type
To build Gantt-charts, we currently use inverted columnrange types. However, if we want to plot another graph type on the same graph, e.g. line, then this will be inverted as well. This causes problems as the x and y values have to be inverted, meaning that the new x data is no longer in order.

Support more intuitive legend customization - (maxHeight/navigation issue)
Namely, I have an issue with the misleading maxHeight property. If you are digging deep enough in the docs to customize the legend to use maxHeight, this property's value should be taken as gospel.
Either that or allow for the navigation (pagination) of the legend to be disabled without having to have useHTML enabled.18 votes -
Add active text scaling to text beneath column charts.
text beneath a column chart has no scaling. after the creation of a column chart with multiple series the text eventually renders in multiple rows rather than being scaled into just one row of text beneath each respective column.

Add 2nd navigator to improve usability of charts with many points
I find it hard to focus on specific parts of a chart once it contains lots of data points: the navigator's "handles" can be so close to each other that it is unusable. My suggestion is the following: show a 2nd navigator if there's a "more-specific data" to show (meaning - the narrowed area itself contains many points).
To demonstrate my suggestion, I implemented this with two separate charts, one sitting on top of the other, with a slightly shorter height (so that the original's chart navigator is still visible):
http://jsfiddle.net/QNV66/Note that this example has only 100 points. It…

Turn off column in column bar chart
It would be really useful if we can turn off (remove from display like when we click an item on legend) each column element in column bar chart.
This could be useful in many cases. Consider a graph with a column of very large numbers and very small numbers (example http://jsfiddle.net/uqA6w/1/). Turning off the column with large numbers (Jan in example) will improve the resolution of other columns a lot. You can zoom, but this is not convenient as you may have to zoom. multiple times. There are even cases where you want to draw a graph with many…

When the mouse is in the tooltip, the tooltip will not disappear
Sometimes user may add link in the tooltip and click the links. But the tooltip will disappear soon. So it is very hard for a user to put the cursor on the link and click it.
Although user can set a long delay to resolve the issue but when the mouse leaves the tooltip tooltip does not disappearfor long time which is not good either.

Area chart with a numerical x-axis rather than a categorical x-axis. Our particular application plots the physical boundaries of metallic engineering sample slugs post-impact. (We're studying shock stresses and strains.) We use Highcharts for all our other 2D plotting and it'd be great to preserve the look and feel for these types of plots.
Currently I have a workaround where I plot an invisible line of the correct dimensions to set up the plot and then draw in the boundaries of the slugs using the renderer methods. It works but it's a hack.

reflow callback
Add a callback to the reflow function, since it uses a timeout you can't execute your own code right after reflow is finished.

Provide a way to integrate Google Maps as a background
I really like how highstock provides a way to move through time and visualize data by selecting and panning. I would like to reuse this functionality on a map. Sadly, the SVG rendered map provided in other suggestions is not good enough for my case as I would like to reuse some of layers and other APIs Google Maps provide, but allow user to move and select through time and then display data a bit like as a scatterplot (only with positions) on top of Google Maps.

mouseOut and mouseOver should work on all series
Currently mouseOut and mouseOver events are triggered only for the highest (in layers) series when multiple series are drawn on the same chart. They should be triggered for any. (The reason is because probably tracker captures all mouseOut and mouseOver events for highest layer.)

A way to combine y-axis labels
I plot multiple series with same Y range for data. If I use same y-axis for all series, then I have only one label displayed for the y-axis. If I use multiple y-axis, then I get redundant ticks which display the same range. Is there a way to have multiple y axis labels for each series, but to display only one ticks for y axis? Additionally, if I hide a series by clicking on legend, label for that particular series should preferably be hidden as well.
