Allow series->data->marker config obj to overwrite plotOptions->series->marker
Use case: I have a series where I would like only the last point to have a marker. This means that I have to create a marker obj for each point in my series data.
With the change I propose I would only have to create a marker object for the last series data point.3 votesYou can apply individual markers: http://jsfiddle.net/highcharts/TtH3V/

For gradient colors, make the gradientUnits option configurable.
We prefer to have the gradient fill the column from start to end color regardless of height. So we had to change gradientUnits: 'objectBoundingBox' instead of 'userSpaceOnUse' on line 2941 of highcharts.src.js.

Split the chart when the values are very large & very small
When the chart has a lot of small values and a few very large values, we can't see the trend of the small values clearly.
Often ,we solve these kind of problems by splitting the charts.
refer to: http://highslide.com/forum/viewtopic.php?f=9&t=1338715 votesThis can be achieved with axis breaks (http://api.highcharts.com/highcharts/yAxis.breaks) introduced in 4.1.0

Offer a minimum width for the navigator scroller
I routinely work with charts that have hundreds or thousands of data points. In these cases, even a reasonably-sized window is relatively small compared to the overall window of data. When this happens, the scroller in the navigator becomes uselessly thin, often 1-2 pixels or even 0 pixels! (Yes, I've actually seen this.) Desktop operating systems solved this problem many years ago by enforcing a minimum width for the scroller. Is there a way for Highstock to do the same?
7 votesThis is implemented and will be released with the first maintenance. A new option, scrollbar.minWidth is added with a default value of 8.
See http://jsfiddle.net/highcharts/YdTpG/ for test case.

Hide Toolbar Button
Adding a button checks to see if the button exists. Removing does not. I suggest adding this in the Toolbar object (around line 5775 in v2.1.5):
function remove(id) {
+++ if(buttons[id]){
discardElement(buttons[id].element);
buttons[id] = null;
}
+++ }3 votes -

Add Navigation bar for Y-Axis in Highstock
My suggestion for a very helpful feature would be to add a vertical navigation bar for the Y-Axis, similar to the navigation bar that exists for the X-Axis, for Highcharts. Would lead to a highly interactive plot, especially suitable for project using scatter-plots

Allow navigator to have multiple data series
Please allow navigator to hold multiple data series. I had a request recently to convert a very large data set into separate categories, so that they could be deselected via the legend, but now I don't get the set represented in the navigator window, because it only will hold one series. And with large data, building one composite set will be too much overhead.

Additional data for point
It would be nice to be able to add an array to a point, call it 'user' or 'data' and make it available to the tooltip formatter.
This way, extra information can be stored in the point and rendered in the tooltip.
E.g. I have a graph that shows how many people are listening to my radio station over time, it would be nice to add the title of the song that was playing to the tooltip.3 votesYou can! The config object is available from the tooltip formatter as point.opoints. See http://jsfiddle.net/Z2GRH/.

Make a build-process to reduce JS size / Select only required chart types
Similar to the jQuery-UI builder, perhaps you could allow users to deselect unnecessary chart types / cut down the JS script size.

overlaid column chart
The current stacking options are: null to disable, "normal" to stack by value or "percent".
Another visualization is to overlay the columns (usually requiring the use of transparency).
As a comparison, please see the stacking options offered by Flex:
