  1. marker

    Hi All,

  2. Dynamic javascript loading as needed

    Good day colleagues.

    Allow me to suggest optimizing the loading of your modules using tools such as script async and defer. I tried to independently select the optimal sequencing of script downloads, but unfortunately, your modules refuse to work.

    For example, I need to load 1 base library (highcharts) and 3 additional modules (export, offline export, wind barb), according to your documentation, I need to add 4 synchronous download scripts to the website header, which significantly slows down the loading of my website and spends browser resources wasted, because I need the output of graphs only at the command of…

    I think for your use case, it is better to load the scripts dynamically rather than using script tags and async/defer. Using async/defer there is no guarantee the scripts are executed in order, which may impose a problem since the modules depend on highcharts.js.

    A better way would be to use require.js to load them async, see https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/amd/simple/. Or to load the ES modules directly, see https://api.highcharts.com/class-reference/#toc4

  3. Patterns in venn diagram

    How shall we add patterns and visibility of series in venn diagram? So that can represent the intersected data in patterns and can also disable the unwanted circle through aps by controlling visibility from aps. If you have any kind of solution kindly reply as early as possible.

  5. The posibility to change data in an Chart

    The possibility to change live data in a Chart, for example in a linear diagram you double click with the mouse on a plot and you get the y value and when you finished edit it, this triggers an event.
    Maybee this feature already exists?

  6. Provide a .NET Standard or Core Wrapper

    .NET Core is growing rapidly in popularity. A highcharts wrapper for cross-platform development in .NET Core is urgently needed.

  9. Improve tooltip.formatter documentation

    Just from the documentation https://api.highcharts.com/highcharts/tooltip.formatter it is not clear what you have to return from your formatter call. It suggests that you always return a string (basend on the provided examples)
    However when you dig into some issues and SO it is clear that for split tooltips you also can return an Array. First entry will be the x-label tooltip and then each following entry is one point.
    Just couple of examples how hard it is to find this is actually possible:
    https://stackoverflow.com/questions/45981514/highstock-tooltip-formatter-if-using-split-true?rq=1
    https://github.com/highcharts/highcharts/issues/6115
    https://github.com/highcharts/highcharts/pull/5976
    and even the type definition is not complete https://api.highcharts.com/class-reference/Highcharts.html#.FormatterCallbackFunction%3CT%3E

    I'd suggest simply extend the documentation…

  11. Publish the map collection data as an React/NPM package

    The maps provided at http://code.highcharts.com/mapdata/ are useful, but in modern web apps most dependencies are managed with a package system, and for JavaScript projects mostly commonly that is NPM. So this suggestion is to publish the map data in an NPM package, similar to the way there's a React wrapper project.

    Noted at https://github.com/highcharts/highcharts-react/issues/55 currently the only way to bring this data into a React project is to do it manually.

  13. Document the order dependency of heatmap.js and treemap.js

    The documentation and examples do not mention that there is an order dependency for these to work right. Please add this so that people know it won't work otherwise.

  16. Allow automatic scrollbar for responsive charts

    There should be a feature where scroll appears or disappears when the div containing chart is resized. When the chart is big enough to fit into available space, the scrollbar should be hidden and when the chart container is resized (reflow called internally), the scrollbar should appear automatically to show the data points instead of making these data points smaller.

  17. Centering label in Highcharts General Drawing

    Can this be achieved by using the Renderer framework, by adding a line of code in .attr ? I've created a flowchart, similar to the one found here: https://www.highcharts.com/demo/renderer. The label text is left-aligned by default but I wish for it to be center-aligned by default, using the Renderer framework, e.g.,
    ren.label('Test is a label', 660, 680)
    .attr({
    fill: 'black',
    stroke: 'black',
    'stroke-width': 2,
    padding: 5,
    r: 0
    })
    .css({
    color: 'white',
    width: '100px'
    })
    .add()
    .shadow(true);

  19. Change export icon

    The export icon is 3 horizontal lines (looks like hamburger menu). It is not the correct paradigm and it does not imply export or download. Please change it or allow using a different icon.

  20. Add vectors based on wind direction and wind speed in HeatMaps

    Hello,

    details..
    1. I'm going to display three data of temperature, wind direction and wind speed in each cell.
    2. Temperature color is limited to 4 types in total.
    2. The direction of the arrow is limited to 16 kinds in total. (0, 22.5, 45, ... 337.5)
    3. Arrow lengths are limited to 10 types in total. (9%, 18%, 27%, ... 90% of diagonal)

    Can it be?
    If you email to me(ycpark@cetech.kr), I send you some examples about the suggestion.
