  4. Could you add more Highstock Indicators?

    I'm studying Highchart and Highstock.
    I'm looking at the indicators of Highstock, but I can't find some of the indicators I'm using while investing in stocks, so I ask if you can add the functionality of those indicators.

    -Request indicators-

    Slow stochastic (Not Stochstic = Fast Stochastic)
    OBV
    Disparity

    If the features of above indicators are already implemented, please guide the directory where to find them.

  8. 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

  9. 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.

  11. 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…

  13. Improve navigator.series documentation

    In the (highstock) navigator.series documentation there is no data property mentioned (https://api.highcharts.com/highstock/navigator.series), however in your example (https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/navigator/series-data/) you provide a data attribute.

    I guess you covered it with the sentence in the introduction 'Available options are the same as any series'. But the problem is if it is not reflected in the documentation it is not available in TypeScript (because I think you generated the sources out of the documentation?)

    Would be great if you can adjust the documentation (and TS type for NavigatorSeriesOptions)

    Posted as an issue here https://github.com/highcharts/highcharts/issues/7729

    In modern app, highcharts and highcharts more are loaded as module and potentially multiple time, but highcharts more cannot be "init" several time without breaking highcharts :(

    Fixed since v8.

    If you find any other module that is broken that way, please report the bug on Github.

    Thank you!
