  1. Like Excel does when you use 2 columns for the labels.See example on http://minus.com/mHNwVqDZO.

    Each item on the category axis falls in a group. The groups are displayed below the axis items. Each group name is displayed only once (centered below all its items). Groups are devided by longer tickmarks.
    Each group can contain a different number of items.
    Possible uses:
    * display structured categories like product and product group or country and region
    * display two or more groups side by side, like gross sales and net sales, or this year and last year.

  3. 'Border radius' on a column chart currently affects all 4 corners of a column identically. Please, could we have the ability to set individual corners at different radii?
    Personally I would like this so that I can round just the top of a stacked column chart, but i think it would be a great addition and allow some nice extra flexibility in look & feel.

  6. All animations in Highcharts use setTimeout. A new feature, requestAnimationFrame (https://developer.mozilla.org/en/DOM/window.mozRequestAnimationFrame) optimize all animations (CSS3, SVG, JS) to have a smooth rendering.

  7. 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…

  8. I would like to have an approximation function in which we can access all the information from the points instead of just the y values. This allows me to not only decide how to group but also an ability to capture information from all the points into the grouped point.

  9. See here: http://forum.highcharts.com/post115029.html

    This would add a chart width/height setting of "auto". For bar charts, the auto height uses the point width and padding options to determine the "correct" height of the plot box, instead of using the size of the container. For column charts, the chart would grow/shrink horizontally to fit all columns.

  11. I'd like to be able to delay the initial animation of the chart until it comes in to view in the browser by scrolling.

    I've tried doing this with js but the whole chart is hidden until it comes in to view which looks odd. I'd like the axis to show and only the animation to trigger when it comes in to view.

  12. http://jsfiddle.net/j99skchd/
    This example displays a gauge from -4 to +4. The series data value of 0.5 would ideally make the gauge colour the range from 0 to 0.5.
    Correspondingly, a series data value of -0.5 would make the gauge colour the range from -0.5 to 0 (and in the example we would make that a green range).

  13. I'd like to specify a stepPosition (such as 'on' or 'between') when step: true. Currently the step always occurs on the actual data point. I'd like to be able to have it step before the data point, so you end up with a plot more similar to a column chart.

    My example is that I have an area chart with overlapping series, but I need a step chart, because I'm representing a fixed number of reads at specific loci on a strand of DNA.

  14. Now legend positioning is automtical and "horizontal first". I.e. when ALIGN:LEFT, legend space reserved on the left firstly and secondly I can vertically align the legend. Only center-aligned legend can be placed at bottom or top of plot area.

    But my designer want to have left-aligned legend at bottom.

    So it seems good idea to add legend option like
    position:={top|bottom|left|right} to specify where the legend space is reserved, and use existing align/verticalAlign options to align legend inside legend area. May be ignore verticalAlign property for top/bottom position (not sure) but apply both alignment for left/right legend.

  15. It would be really nice to have a custom date format option implemented in HighCharts / HighStock, so that it could parse dates from different sources.

    In case it's useful, here's an example of how such feature is implemented in a couple of other JS popular libraries:

    http://momentjs.com/docs/#/parsing/
    http://c3js.org/reference.html (check "data-xFormat")

    Cheers!

  16. Similar to Tof's idea but I believe it's a bit different, it's not just max that I want to show, but a full scale for each series on the polar chart. I also need to show these axes in two different places - right now the only workaround is to layer one set y-axis of labels on top of another. Please see this image for an example of what I'm looking to do in highcharts: https://s32.postimg.org/5gnejaln9/polarchartwithmultipley_axes.png

    In addition, I am unable to show a single line for the axis right now, the only way to show…

  17. At SSB we have a lot of auto generated charts, and need symbol markers on charts to fulfill accessibility requirements, but on a lot of our linecharts the point density is so great that the chart becomes unreadable, but not dense enough for the "null" option to kick in and remove the markers.

    Therefor, what we need is that marker symbols appear at the end of each line, while also appearing at the corresponding legend.

    (We tried a solution that was posted in another feature request, but found no way to implement it with auto generated charts and also it…

  18. Provide a standard way to get highchart drilldown with breadcrumb navigation.
    For example in the fiddle
    https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/pie-drilldown/
    where browsers data is present, a simple breadcrump should be displayed like "browsers / chrome".

  19. In Stacked bar/column is there any way to sort the category names:

    Example :

    https://jsfiddle.net/vasjav1/ywspnocd/1/

    it should be sorted as

    ['Apples', 'Bananas', 'Grapes', 'Oranges', ' Pears']
