  2. Double logarithmic axes and draggable points

    The draggable-points module handles logarithmic axes pretty bad, see this fiddle: https://jsfiddle.net/5bkf7pL8/2/

    I did however find an old stackoverflow issue regarding this ( https://stackoverflow.com/questions/18036117/high-charts-draggable-not-working-for-log-scale ) where a solution was found for the old experimental plugin.

    This example ( http://jsfiddle.net/yn1jaL60/ ) shows that dragging is freely permitted, but that there are some bugs with the rendering of the markers, it would seem. So, would be nice to be able to do the actions in fiddle nr 2, with the performance and visuals of fiddle nr 1.

  3. Export multiple chart data into .CSV and .XLS files based on timestamp

    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

  4. World map with country's subDivisions (states)

    Following another suggestion to use ISO3366 subdivision Codes (https://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/37798789-add-iso3166-subdivision-codes-to-maps) it would be nice to have a world map with all subdivisions. We already have most of the countries mapped individually, in fact, there's also some continents mapped this way too. But a full world map with subdivision is missing.

    Thanks!

  5. item

    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

  7. 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.

  8. Ribbon Chart

    A "ribbon chart" which is a new way to look at a stacked area/column chart. Looks much prettier and easier to compared to the normal stacked styles that have commonly existed in most chart systems.

    This site wrote up an article about the style being added to another chart system.

    http://radacad.com/ribbon-chart-is-the-next-generation-of-stacked-column-chart

  9. Define two font colors for datalabels depending on inside or not

    In a bar chart I found no way to define if datalabel is inside or outside of the bar. Highcharts computes this depending if the text fits inside or not.

    When you have a white background and a colored bar, and you want to have the complementary color for the text depending on inside or outside of bar there is no way to find out which color to set, because highcharts positions the text dynamically. e.g. on changing browser size, the position can swap from and to inside or outside of the bar.

    Sample: some labels are inside and some…

  11. Grouped Categories on Export Server

    Grouped Categories on Export Server.

    It seems I can't find any solution for the grouped categories for export server. If there's a solution how to bind this, so it will lessen my time of development. we already using the blacklabel plugin for grouped categories but it only works on web but not on export server. Thanks!

  13. HighStock.js: add parameter to chart.redraw(numberOfPointFromTheEnd) API method

    Hello,

    I develop application related to stock market. I have a case when there are three charts displayed (area, candlestick, column) that needs to be updated when stock price is changed but not more than one time per 2 seconds. Each chart type (area, candlestick, column) can contain 15000 of points. Here is live demo: https://jsfiddle.net/ogorobets/8gb54cyh/5/. As you can see there application hangs out because of big load.

    My proposition is to have "numberOfPointFromTheEnd" parameter in chart.redraw() API method to redraw only last few points but not whole chart. This way redrawing chart can take much less time.

    As…

  14. Add categories

    Hi
    There are a categories in the chart for several tasks
    An example in the link https://www.highcharts.com/gantt/demo/interactive-gantt is to add a task that is not what we want.
    Is it possible to add and edit categories?
    For example, there's a button to get a text and add to the list of categories
    Thank you

  15. Add an option to the navigator to behave like the range selector

    I would like to have an option in the navigator that avoid filtering the series on the main chart. This option will allow the navigator to behave as the range selector.

    At this moment, the navigator can be easily customized with the JS API and CSS; my goal is to style the navigator to be a horizontal bar with handles that can be used as the range selector.

  16. Native option to zoom and center highmaps on nonempty regions

    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}

  17. waterfall: non-numeric total date xAxis label

    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:

    There are a few suggestions of this here in UserVoice, but those seem too scenario-specific and I thought I'd just make a compilation of all of them here.

    Even something as simple as just providing an additional object for each category that contains what points it has from each series.

  20. Many-to-many relations/interactions of charts

    This suggestion is an outcome of my longtime involvement with the modelling of many-to-many communications, initially at the RAND Corporation and subsequently at the University of Oxford with some intriguing results in applications such as predicting voter behaviour (see this article http://analytics-magazine.org/voter-motives-and-messages/).

    Recently, I found myself involved in the objective analysis for the determination of the best e-banking UI; as it is apparent that soon enough the best bank will be the one with the best UX/UI design.

    Here we used highcharts to visualise our findings. Corellating for example the Use Case scores vs. the Functionalities available using a…
