  1. The idea would be to have Highcharts inherit classes from the framework which enable responsive behavior based on device specs, similar to the 'col-" classes in the latest version of Bootstrap. I would think that responsivness should extend to the various attributes of the graph like scales, etc.

  2. 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

  4. Show only a given number of levels at the same time.

    Keep in mind the possibility of more granular control depending on which level the user is on.

    E.g display levels 1-3 by default, and show levels 4 and 5 only when the user drills into level 3.

  6. i.e. zooming with wheel and dragging with mouse

    an option in the chart section beneath zoomtype with name (for example) zoommode would be nice, with two options "box" (as current since you drag the mouse to make a box) or "wheel_drag" (because you use the wheel and can drag)

  8. Hello,

    I've made some research and haven't found any option for tooltip to follow mouse cursor (height-wise). It would be one useful option if a series contains a lot of peaks and spikes or there are two series which values are very different and samples aren't aligned (time-wise). It could give one much smoother experience.

  9. It would be useful if you could improve the series line highlight (or equivalent on other chart type) on legend hover event.

    Following what is currently achieved on hover state by default, where it highlights the series line by adding line width, it should be possible to dim or gray out the other line series in the graph.

    This can be easily done by using events on legend items hovering: http://jsfiddle.net/vitorbarbosa/qpByN/
    however, it would be nice if it was implemented natively and for other chart types.

  10. I'd like my point mouseOver event to only fire when I hover over the point or a specified radius around a point. Currently when you hover over a series the nearest point is selected and it's mouseOver event is fired even if the mouse is not near the point. This makes it difficult to detect and handle true mouseOvers on the point.

    Currently the tooltip snap setting applies to the mouseOver event even if tooltips are disabled. If it was separated out and made it's own setting then it would make event handling mouseOver events simpler.

  11. At the moment X axis error bar and y axis errorbar( using inverted option) are available.
    It would be great to add the ability to have them both together in the same chart.
    Example: http://www.jfree.org/jfreechart/api/javadoc/images/XYErrorRendererSample.png

  12. 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.

  13. It would be better if we can set the number of times the graph would animate. This would be most useful in case we have graph placed in heavy loading web page, where before the whole web page gets loaded, the animation of the graph gets completed. so that user is not able to see the graph animation. user just see the graph which is static and not animated.

  14. 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…

  15. I have a need to display an area above (or below for reversed y-axis) a line. I can certainly specify a threshold above the highest value in the series, however this breaks the yAxis ability to dynamically pick the maximum end of the range based on the data. So I suggest either (a) have an option for the yAxis to ignore the threshold when dynamically choosing the min/max of the range, or (b) having special "positive infinity" and "negative infinity" values for the threshold that would of course be ignored by the yAxis ranging.

    Thanks!

  16. Printable documents benefit from vector based images. For example when embedding an image in word or powerpoint it would be more useful to have emf or eps charts than png. Unfortunately svg is not support by most non-browser software.

    Is it possible to add eps or emf output to the list of available formats?

  18. A top level graph to be a bar (actual values) and line (expected
    values) graph for various categories. Then when you drill down into a
    category, a bar (actual values) and line graph (expected) again
    showing data over time for that category.

  20. I've created javascript functions to automate some char creations.

    I may not know what the names of my series will be, nor their length, but I know how I want to organize them in my legend (2x3, 2x2, ...).

    It would be great if we could set in the legend's options the number max of items per line.
