Show only changed axis labels
Given following x- or y-axis categories.
["Jan", "Jan", "Jan", "Feb", "Feb", "Mar", "Mar", "Mar", "Mar", "May"]It would be great if we could show only changed labels (like a more advanced "labels.step" option). Like follows:

Add footnote textbox immediately below chart.
I have several charts for which I need both subtitles and footnotes to clarify/explain the presentation of data (and I always use credits). When displaying on the web it is easy enough to add a paragraph under the chart, however I also need this footnote when exporting the chart. I would envision a simple text box above the credits section.
There is a similar suggestion that was closed with the suggestion to use subtitles ( http://jsfiddle.net/sGv32/5/ ), but this suggestion will obviously not work if subtitles are already being used. Also, in Chrome, the chart tries to display below the…16 votesHere’s an example of how to add a responsive and exportable text box programmatically: http://jsfiddle.net/highcharts/WwPFN/

Allow an array of dataLabel colours
This would mean if the user had specified a number of different colours for the chart, we could then match the colours of the dataLabels, either to be the same if we wanted, or to invert if we want to put the labels over the bars, columns, slices etc.
So if our first bar was dark we could set the first label to be white, and if the second was light, the second label would be dark.4 votes -

The hole percentage of doughnut chart should be based on diameter of doughnut rather than plot area.
Now the hole percentage of doughnut chart is based on plot area, but the diameter percentage of doughnut chart is also based on plot area, so user might set same percent value for hole size and diameter and the doughnut will be rendered as unexpected result, here is the detail http://highslide.com/forum/viewtopic.php?f=9&t=19252.

Set off negative against positive values in stacked charts
It should be possible to sum up negative and positive values in the same stack (like excel does for area charts by default).
Currently positive and negative values are stacked seperately above and below the x-axis. To keep BC and keep the old behaviour as well a new stacking mode should be added IMHO.

Highstock data grouping UI
Currently Highstock allows you to select a zoom factor (buttons on the top left), but the data grouping is automatically select.
I suggest to make it possible to have a data grouping UI similar to the range UI that lets a user choose/enforce the data grouping interval.
Additionally if automatic grouping is used and the user did not override the grouping, the currently used data grouping range is highlighted on the buttons.

One digit month format
One digit month format (i.e. "2" instead of "02") is not yet supported.

axis option minorTickCount
Currently if minorTickInterval is set to 'auto' then the calculation to determine the minor tick interval does a divide-by-5 on the regular tick interval. I would like an option to change this magic number 5 to something else.

plotBand hover state (similar to marker) to change color, etc.
Just like how you can change the fillColor of a marker on hover, I'd like to be able to change the color of a plotBand on hover.

Add borderDashStyle to bar and column plotOptions
In addition to the current capability of setting borderColor, borderWidth and borderRadius on bar and column plotOptions, it would be helpful to be able to configure a dashStyle for the border.
In our use case, we're drawing a stacked bar chart, and we'd like to display the final stack series as a empty bar (white background) bordered by a red dashed line.

make crisp rendering an option
crisp causes uneven gaps in series. we have a lot of columns side-by-side on our charts, and when the crisp rounding causes a gap every 10 bars, it's almost like they're grouped. i disabled the crisp function (by just returning the raw values), but if each series had an option to enable / disable crisp rendering, that would allow for users to make the charts that are the cleanest to them and not have to edit the source.

It would be better to add a new property to control that the x-axis label can be rendered above x-axis.
Now the x-axis label can just be rendered below x-axis, I knew it can set xAxis.labels.y offset to make the x-axis label to be rendered above x-axis, but since the label size depends on font settings, we can't set a accurate y offset. I would be better to add a new property in axis options to control this case.

Better performance
At the moment I load two very huge charts. After loading I do this:
var series = chart1.series;
$.each(series, function() {
// some stuff
});But that's very slow and freezes my browser so it takes 5-10s to load. Can you make better performance?
