1. Dynamic histogram charts

   I would love to see interactive histogram charts. Ideally I would pass a single series of data to the chart, along with a default number of bins. Then the user would be able to change the number of bins and the data would be re-binned and the chart re-drawn. Bin labels would be need to be regenerated automatically as well, either from the range of each bin, or its center-point.

   An example:

   Series: { data: [1,2,1,2,1,2,3,3,4,4,4,4,4] }
   Histogram: { defaultBins: 2}

   would become:

   xAxis: { Categories: [ "1-2", "3-4"] }
   Series: { Date: [6, 7]}

   Then if the user changed number of bins to 4 (via a slider or text entry), the data would be rebinned as:

   xAxis: { Categories: [ "1", "2", "3", "4"] }
   Series: { Date: [3,3,2,5]}

   and the chart redrawn.

   This feature would be especially useful in scientific applications, where histograms are frequently used.

2. chart within tooltips

   Is possible to display a chart in the tooltips ?

   Like a drilldown chart which is shown at tooltips.

   I have try a few simple solution with it :
   1. I'm set useHTML option to TRUE, and applying <iframe> syntax. So basically, i make 2 chart.
   2. I'm set useHTML option to TRUE, and applying <img> syntax. So i have 1 Chart & 1 Image.

   What I dislike from my method :

   Method 1. I cannot customize tooltips size.
   Method 2. I will have a chart image, not an interactive chart

4. I suggest you a new feature for "donut charts"

   I suggest you a new feature for "donut charts" (with 2 or more circles, like "browser" and "version" in your example).
   I have a real need in this feature. What is it?
   When user click on one label at the legend (which has 2 labels: "browser" and "version") this label and circle at the chart display none.
   The other data at the chart (i mean the next circles, more outlying) must regroup.
   So, if there are 2 same "1.1" version, with "5%" and "7%" at the second circle, after the regroup it must display "12%" in one sector.
   I realy need this featere in donut charts and able to buy it, if you do this.

7. 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:

   |
   |
   |______________________
   |Jan|||Feb||Mar||||May|

8. 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 footnote, and is completely flattened out.

   Here’s an example of how to add a responsive and exportable text box programmatically: http://jsfiddle.net/highcharts/WwPFN/

9. 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.

12. 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.

13. 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.

16. 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.

    You can implement it by defining your own dateFormats to extend the built-in ones: http://jsfiddle.net/highcharts/QECBE/

18. 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.
