  1. Add Print and Export events handler

    It'd be useful to have access to some more events, specifically I was thinking about 4 new events which could be captured and managed by dedicated handlers: onStartPrint, onFinishPrint, onStartExport and onFinishExport

    The first two are related to the act of printing the chart via the print button, the other two are related to chart exporting.

  2. x zoom for multiseries data

    I have four series of data, and each series only has one data point. I would like to render these data with x-dimension zoom ability as good as 4 data points in one series. If this is a duplicate topic, I am really sorry, because I could not find a similar one.

    Here is the fiddle: http://jsfiddle.net/yMSCZ/8/

    I was trying to approach it by adding dummy x value to each data point from each series: http://jsfiddle.net/yMSCZ/9/ But it did not work out.

    I understand in the first fiddle, HC will treat all the four points with the same x index,…

  3. Exporting charts just by right clicking on them

    Hi

    I would like to suggest a small improvement concerning exporting. At the moment, user that wants to save a highchart has to click on a download icon and choose an option from a dropdown.
    A small but great improvement would be to do the same, just by right-clicking on a chart.

    You just right click on a chart -> save as -> desired format and voila!
    I am not sure if sucha feature is possible to implement, but it would be neat to have this! :)

  4. Restore "target" option in the "credits" configuration

    It would be most useful to restore the "target" option in the "credits" configuration so that when the user clicks on the credit text (usually in the lower right angle of the graph), the link can be opened in a new page instead of the current one.

  5. 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.

  7. Tooltip delay

    I would like the tooltip to have a 'initial delay' - such that it acts more like a typical tooltip. I.e. the tooltip only shows after the mouse is stationary for a specified time, and then tracks data points instantly once shown.

    Additionally, I would like the tooltip to be able to be replaced by a callback which provided the point values, such that they could be displayed elsewhere. So, for example, I might want to display the values of the currently tracked points in a div to the right of the graph, while still retaining the crosshair functionality.

  8. chord diagram

    A chord diagram or an extended diagram is basically used to show data flow between multiple entities. We can have a circular chord diagram or an extended one.
    Currently we are achieving it through d3.js, but that requires lot of complex coding

  9. 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…

  10. Brushing - Selecting multiple data points with the mouse

    This would be a fantastic feature - the ability to select multiple data points by creating an enclosure using the mouse. e.g.Outliers could be selected in one movement and used filter other data in the app.
    See Stephen Few's Newsletter for more information - http://bit.ly/9A8wiD

  11. Data labels with collision avoidance and connectors for scatter and bubble charts

    Scatter and bubble charts do not seem to support collision avoidance for data labels. Along with collision avoidance, connectors that link the points to the data labels would be very helpful.

    Thank you for the great library.

  12. Position of axis

    I would like to be able to choice the position of my axis, for logarithmic chart or not, like this image : http://img15.hostingpics.net/pics/881099axis.png
    Indeed, I need to split my chart in 4 part in taking the x-axis and the y-axis in a exactly point.
    Have you got a solution or is it possible to take this in the roadmap?

    Thanks

  13. Provide pointWidth as a percent value

    Consider the scenario that there is a re-sizable box plot chart. When the chart is reduced to a smaller size, box plots start overlapping because pointWidth can only be given in pixels. And when the chart is enlarged, box plots are seen to be smaller with respect to chart size. The same goes for column charts, etc.

    So, there should be a feature where we can provide percentage values for pointWidth.

    I don’t really think this is needed, please correct me if I’m wrong. Instead of using pointWidth, you can control the width by using pointPadding, which is relative. The pointPadding option allows you to pack the boxes tightly, with a 50% gap or whatever, and it will respond to different chart widths.

  15. Label at last data point

    It would be nice to show a label between 2 ticks at the x position of the last data point.
    This way you can see the most recent entry more clearly, and without having to hover over the data point.

    Hi, this feature is prevented in two places, because there were problems with text being selected when trying to zoom in. See https://github.com/highcharts/highcharts/issues/3224.

    If you want to enable text selection, there are two lines where the event handling is prevented. If you comment out both these lines, your users can select text:

    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L756
    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L813

  18. Pie Title

    Introduce a pie title that displays the series name. There should be option for placement: 'above', 'below' and 'inside'.

    Pie titles are necessary when you use charts with 2 or more pies is them.
    See these 3 mockups I made:
    Above: http://jsfiddle.net/kzoon/Nw2cC/
    Below: http://jsfiddle.net/kzoon/qMvc9/
    Inside: http://jsfiddle.net/kzoon/8SdqV/

  19. chart.options.zoomed parameter

    In some cases I would like to know from outside the chart if the chart is in a zoomed in status or not without having to record initial state and later compare. This should be quite easy to do internally as you are already monitor this status for the "reset zoom" button.

    See discussion : http://highslide.com/forum/viewtopic.php?f=9&t=24822

  20. Support offset of x axis with concrete Y scale value rather than pixel offset

    Now highcharts support setting offset pixel of x axis to specify x axis position,but is not convenient, it is better to support setting offset of x axis with concrete Y scale value rather than pixel value. please see example http://jsfiddle.net/cxARQ/5/ , I want to set position of x axis at 50 of Y axis, but it is hard to set exact position with pixel.
