  1. It would be very useful to calculate the speed of change in the y axis at every point in the time series. Something like this:
    chart.series[0].points[0].y.speed(year)

    speed(Year) would calculate the rate of change per year, or month or day of the Yaxis variable,

    you could also implement acceleration
    chart.series[0].points[0].y.acceleration(year)

  3. Hi
    New pattern need to be created from the parent circle patterns for intersected data .
    Example: If one of the parent circle has vertical line pattern and other parent circle has horizontal line pattern, the intersected part should have pattern that must be the result of both parent circle. In this case it should look like square box (combination of vertical and horizontal circles).

  4. I have a requirement for heatmaps which involves applying a patternObject as a color for zones applied to the x-axis, but I also need the pattern fill to respect the color applied by the colorAxis.dataClasses. Is there currently a way to do this that doesn't involve applying classNames in styled mode?

    Actual behaviour

    I need the annotations labels to respond to resize option , that html provides like this

  7. PlotBands require an axis and two values from/to.
    I think can be a good idea to extend some features:

    1) If to is null band can stretch in positive axis direction
    2) If from is null band can stretch in negative in axis direction
    3) If to and from are both null plot band fill the chart area

    4) Plot band can accept also axis2, from2, to2 parameters, if defined, plot band stop in axis2 direction instead of stretch,

    Here a demo prepared by mateuszkornecki

    Thanks.

  8. Hi Team,

    Can you please help me on below requirements :

    When I click on the nested node(series) it is displaying a nested node drill down, and all the nested node should appear child nested and child to another nested child and so on….

    I mean there shouldn’t be any limit for generating new node(series), and also It should be stoppable if required.

  9. Hello,

    As I tried explaining here : https://stackoverflow.com/questions/54947746/mix-categories-and-subtasks-in-highcharts-gantt

    I was wondering if, in Gantt, it was possible to use parent/subtask (folding and unfolding) while also having multiple tasks on a same "line" (mixing "Interactive gantt" demo with the "subtasks" one). Apparently it is not and so I'm wondering if this behavior can be expected in the future.

    For now, I think I will use css classes (or another way of identifying the parents/children) to add a bold + folding icon to parents, and to .hide() the depending yAxis when clicked (that means having an event on the label, but I'm…

  11. plotBands Labels right now if there is no any space (for example: horizontally), specially in highstock 7.2.0
    will be shown out of width of the rectangle.

    so it will be better we have an option and by defualt be on that make them hidden when no space, specially in xAxis.

  12. Steps to replicate –
    Click on the following URL -https://www.highcharts.com/gantt/demo/interactive-gantt
    Click on “Edit in JSFiddle”.
    Try dragging “prototype” or any other node.
    Unlike nodes which can be dragged by user at run-time, (dependencies) dependency arrows cannot be dragged by user at run-time.

  14. In the existing docs, it states:

    We recommend to always include the accessibility module, unless there is an explicit reason not to do so. Including this module will make your charts compatible with assistive technologies used by people with disabilities, and also improve the usability of your charts, helping you reach a broader audience. Including the Accessibility module will also help with SEO by making your charts more visible to web crawlers.

    I seriously commend you for providing this support, but is there any reason not to make this the default and opt-out instead of opt-in?

    Web dev in general…

  16. It would be a good idea to overlap the value of over 100%. So it is possible to display the value.
    My idea would be to overlap the circle like on Apple Watch.

    Apple Watch activity chart: https://www.wareable.com/media/images/2017/06/acvtiivyt-1496340445-hoFP-column-width-inline.jpg

    I think that might be useful for some users.

  17. It would be great if there a feature to move the node elements in the Sankey chart. In some cases you don't recognize much by the intersections of the flows.

    Like in d3: http://blockbuilder.org/timelyportfolio/79350d7475a5709b051e

    This allows you to move the display according to your wishes and i think that is a important feauture that doesn't exist.

  18. In the funnel 3D diagram, when the values of layers differ too much, the layers with the smaller value is extremely hard to see in the funnel diagram. Can you update the api to support connecting lines between each layer and corresponding value?

  19. In the timeline graph, if there is sufficient height in the graph, it would be great if the points that are hidden because overlap: false is set, that if there was space to render "two" (or more) rows of boxes (with longer connecting dots) that those boxes were rendered above/below the original boxes.

  20. Please add multiple targets for bullet charts. We have to need to show multiple targets; eg soft targets, hard targets, benchmark etc.

    Ideally, each target would be a different colour and there would be a hover-over legend
