  1. Hi Team,

    First of all great work on the Highcharts. It is very helpful in far many way I can describe in representing complex data.

    Recently, I have come across a requirement where I need to use Dual-Xaixs of which one is a grouped. i.e for instance, say my bottom X-Axis is of months my top X-Axis should be of quarters (3 months ~ A quarter). I do not see any example or hacks which I can use to achieve this. Please, let me know if this is possible. If so, Please point me in the right direction so that…

  2. It would be nice if there was a single option that we could apply our dateTimeLabelFormats for all objects that use that option instead of having to copy and paste it separately for tooltip, y-axis, x-axis, etc.

  3. Not sure what is the name of this type of chart exactly but I need something that visualizes a progress through a multi-step process. Something like this - https://www.vectorstock.com/royalty-free-vector/progress-bar-user-interface-design-vector-16715259.
    I couldn't find anything in your examples.

  4. I think currently high chart support legend at single position, but I would like to display the legend on top as well as on bottom of the chart, because if the chart is bar chart and more values then user need to scroll the page again and again to view the legend.

    So please let me know if it is already implemented or add to todo's list.

    Multiple legends feature is currently planned and the implementation has already started.

  5. We need to have a pie chart that supports motion player and drill-down feature at the same time

  6. For a StockChart every time the user adds, removes or modifies an annotation or an indicator, either over the annotation-/indicator-popup or by dragging an annotation-control-point directly, an event on the chart instance should be fired, so that you can e.g. automatically save the chart-state every time something has changed.

    Maybe something like:
    Highcharts.Chart#events:annotationChanged
    Highcharts.Chart#events:indicatorChanged

    Hi,

    Thank you for submitting the idea.

    Basic events are already here: on chart level we have addSeries (https://api.highcharts.com/highcharts/chart.events.addSeries) and series remove – implemented, but not a part of documented API (demo: http://jsfiddle.net/BlackLabel/0cosmk2g/) or similar series destroy (the same situation).

    For series update you could use series render event (not a part of documented API).

    Events for annotation update are not yet implemented.

    How to resolve:
    Generally, this could be implemented through extending Highcharts. Related functions that create, update and destroy annotations could be wrapped to fire additional events. I’ll try to provide a POC later this week.

  7. Hello,

    First of all thanks for great library. In our company we are using licensed version and we need static library support for cocoapods.

    Using "usemodularheaders!" in Podfile causes to have pods as a single static library in the project which results in smaller app size and reduced initial load time for the app. We discussed the support in github : https://github.com/highcharts/highcharts-ios/issues/150

    We will really appreciate if this is supported.

    King Regards

  8. I asked for chart.rangeSelector to be added to the typescript definitions and was told it's a private class. It can be used as described here: https://stackoverflow.com/questions/48798659/programmatically-set-rangeselector-in-highcharts

  11. I have some usefull trick to center map on non empty (with some data) regions to avoid this case:
    https://gyazo.com/35fd0d74d3e773f694790c5fc0c95ece

    and now i can show only usefull part of highmap, by default:
    https://gyazo.com/d7ca32d8ce8b1535bddd331a997c67b8

    {code}
    const points = this.chart.series[0];

        let minX = Number.MAX_SAFE_INTEGER,
            maxX = Number.MIN_SAFE_INTEGER,
            minY = Number.MAX_SAFE_INTEGER,
            maxY = Number.MIN_SAFE_INTEGER;
    
        if (!points) return;
    
        this.chart.series[0]
            .getValidPoints()
            .forEach(item => {
                if (item['_minX'] && item['_maxX'] && item['_minY'] && item['_maxY']) {
                    minX = Math.min(minX, item['_minX']);
                    maxX = Math.max(maxX, item['_maxX']);
                    minY = Math.min(minY, item['_minY']);
                    maxY = Math.max(maxY, item['_maxY']);
                }
            });
    
        this.chart.series[0].xAxis.setExtremes(minX, maxX, true);
        this.chart.series[0].yAxis.setExtremes(minY, maxY, true);
        this.chart.redraw();
    

    {code}

  12. Some charts, such as heatmaps, frequently have categorical x and y axis values. Converting categories to numerical indices adds extra code and possibility for error. X-axis categorical values can be specified within an object array using the "name" field. I suggest a similar field ("yname") to specify y values by name, rather than index.

  13. In most gantt charts, the ability to resize and drag in addition to the chart for the gantt charts table has also been implemented.
    This means we can change the size of the table columns
    We can also move the table rows with tasks

  16. The totals column on a waterfall with a date is always placed on the timeline somewhere. The totals isn't actually a part of the date timeline, it's an aggregated value and should be able to be marked as such.

    Basic ask is for an additional tick that is customizable that represents the placement of the placement of the connected totals column.

    Problem described more fully here:
    https://github.com/highcharts/highcharts/issues/10458

  17. I like the new "Item" chart. But I have been frustrated with the management of real. It would be really nice if the last item point/symbol could be cut according to the decimal corresponding.
    https://jsfiddle.net/9n3kbyzs/
    Even if we want to display a percentage, the rounding method (it's a ceiling round) result in a chart with 102 items (I don't want to round number before because on hover I want the real value to be displayerd).
    Thanks

  18. I need to have color that is different from the parent set for the intersected part in the venn diagram and then if I give pattern then the pattern must be applied to the given portion with the same color that is specified for that particular area.

  19. Hi Team,

    Request you to implement a functionality to export the data of two charts into .CSV and .XLS files in such a way that the exported files have data grouped based on timestamp and not just appended one to another.

    Please find below an example :

    Export File Data with current functionality :

    27-05-2019 12.5 45.68 67.8
    27-05-2019 14.5 70.98 90.87
    28-05-2019 10 15 90
    28-05-2019 12.5 14.5 89.6
    29-05-2019 67.5 78.5 67.5

    Actual Export File Data needed :

    27-05-2019 12.5 45.68 67.8 14.5 70.98 90.87
    28-05-2019 10 15 90 12.5 14.5 89.6
    29-05-2019 67.5 78.5 67.5
