Highcharts Javascript API

  1. 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)

  2. Sorting Category names in Stacked bar/column chart

    In Stacked bar/column is there any way to sort the category names:

    Example :

    https://jsfiddle.net/vasjav1/ywspnocd/1/

    it should be sorted as

    ['Apples', 'Bananas', 'Grapes', 'Oranges', ' Pears']

  3. 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.

  4. 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}

  6. 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!

  7. 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:
    https://github.com/highcharts/highcharts/issues/10458

  9. Add ability to toggle (show/hide) category visibility

    Here is an example scenario where this would be useful: https://jsfiddle.net/lanimelrok/6eodqvwy/

    This has been asked throughout the years plenty of times. Here’s a few from a quick Google search:

    https://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/3517780-show-hide-one-or-more-bars-in-bar-column-chart

    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.

  10. 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…

  11. Automated scale breaks

    The implementation of scale breaks when there are large differences between the high and low values of the data being plotted.

    A sample can be found in the below link, implemented in the old Dundas Charting tool.

    https://origin2.cdn.componentsource.com/sites/default/files/resources/dundas/538201/WebChart2005/Scale%20Breaks.html

    The Highcharts feature yAxis.breaks is useful only when the difference between data points is known or when the data is small. The data is dynamic in our case and can be large and the breaks need to be automatically drawn considering not a single series but with respect to all the series present in the chart.
    Thank you.

  12. Static library support

    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 "use_modular_headers!" 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

  15. Duplicate Legend

    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.

  19. Resize columns and drag&drop feature in the gantt charts table

    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

  20. Support for non-numerical y-axis object array specification

    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.
