  1. 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.

  2. Gantt chart is really cool but performance limits you to maybe 10-20 rows. We need to support over 1000, with interaction. Animation is not important. Currently the boost module doesn't work with gantt, but if it did it would be truly awesome.

    Thanks for writing! The Boost module deals with the data points, in this case it would rendering the rectangles for the tasks.

    I don’t think enabling Boost for Gantt would make a very big difference. Rendering 1000 rectangles in SVG should’t be a problem in the first place. I suspect the performance bottleneck is something else, like the grid axis or something.

    Can you share a demo of your problematic chart, where we can do some profiling?

  5. 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.

  6. 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

  7. 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…

  8. 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.

  9. 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

  10. 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.

  11. 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.

  12. 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/

  14. Originally described here: https://forum.highcharts.com/highcharts-usage/surface-pyramid-chart-t39503/

    What you have is just a Linear Pyramid: http://jsfiddle.net/cristiscu/sbt6bbfh/6/. Top segment's height is 15% of the full pyramid height.

    Surface Pyramid: http://jsfiddle.net/cristiscu/sbt6bbfh/7/. The only change was in the pyramidMode value. Top segment's area was made bigger, to show 15% of the whole pyramid surface.

  15. 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.

  16. 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.

  17. 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.

  19. When there is no data to display, the message shows up on the chart. But there are things users might want to do in such a situation. For example, I have custom navigation buttons which lose meaning when there is no data. Some might even want to remove the context menu button. It would be great if there'd a callback where you could add/remove elements to/from the chart.
