  2. At the moment there is no support for 3d line charts with multiple series. Something like this

  3. http://www.w3.org/TR/SVG/painting.html#ShapeRenderingProperty

    Allow setting of shape-rendering attribute in order to enable speed optimising.

    Code modification example:

    SVGRenderer.prototype = {
    /**
    * Initialize the SVGRenderer
    * @param {Object} container
    * @param {Number} width
    * @param {Number} height
    */
    init: function(container, width, height) {
    var box = doc.createElementNS('http://www.w3.org/2000/svg', 'svg'),
    loc = location;
    attr(box, {
    width: width,
    height: height,
    'shape-rendering': 'crispEdges', //suggest to add this by config

  4. When there is no data to display, the message shows up on the chart. But there are things users might want to do in such a situation. For example, I have custom navigation buttons which lose meaning when there is no data. Some might even want to remove the context menu button. It would be great if there'd a callback where you could add/remove elements to/from the chart.

  6. In a chart with data plotted on and datetime x-axia i would like to position tick labels between ticks rather than on ticks. An when i zoom they still appear in the center to the right of it's tick.

    for example i have a tick on August 1st and another on September 1st and my date formate is MMM. I would like to see 'Aug' centered between the August 1st tick and the September 1st tick

    This would definately be a nice feature. I believe we would need two types of label placement on datetime axes. Interval labels would be placed between ticks. For example a month name. But if the interval spans two months, like August-September, the label would have to be placed on the 1st of August.

  7. Let's say I have a chart similar to http://jsfiddle.net/k7n8cf8m/
    There are two lines with almost same data.

    I've got a question if is there a possibility, to present those lines joined together, one above, second right below (without padding or anything, just 2 glued together lines). I mean it shouldn't overlap each other, but display like a rainbow instead.

    Something like that: http://jsfiddle.net/BlackLabel/3goqaqfj/
    But without changing data values.

    Is there a chance to introduce something like that in near future?

    This is a bit similar to the minPointLength option – https://api.highcharts.com/highcharts/series.column.minPointLength, which aims to ease readability when points overlap. It also has the same logical problem: If a small offset is added for multiple series or points after each other, eventually the points will be drawn off scale.

    Here’s a small plugin I wrote that offsets the series by an optional amount of pixels per the series index: http://jsfiddle.net/highcharts/vgdga7vw/1/. As you see, it doesn’t actually consider if any offset is necessary, plus when you have a lot of series it will be off scale.

  8. Please, add the possibility of specifying the gapSize in seconds (eg gapTime). It will be very-very useful for timeline charts for Highstocks and Highcharts.

  9. Rangeselector is great, but I have only seen it with dates on the x-axis. Is it also possible to have numerical values instead?

    I would expect it to be relatively straight-forward. If not, is there a reason for not supporting it?

    Thanks!

  11. Create a service similar to https://pdfcrowd.com/.

    Create an API endpoint that can convert settings into a file format (PNG) that is charged either per conversion or annually.

    The API would take our chart settings and chart data, plot the chart on your server side and return to the client a PNG (or other supported file types) of the chart we requested.

  12. With Highchart version 3.0, the chart does not get rendered on mobile orientation change. I am not sure if this is available with Hightchart ?

    Highcharts doesn’t do anything internally on orientation change, except it reflows if the window.resize event fires.

    You can add your own listeners to orientation change though.

    What does the case look like? Is there a problem?

  13. It would be interesting to have the width of the bars adjusted automatically. Something similar like this: https://js.devexpress.com/Demos/WidgetsGallery/Demo/Charts/AutoCalculatedBarWidth/AngularJS/Light/

  14. Steps to replicate –
    Click on the following URL -https://www.highcharts.com/gantt/demo/interactive-gantt
    Click on “Edit in JSFiddle”.
    Try dragging “prototype” or any other node.
    Unlike nodes which can be dragged by user at run-time, (dependencies) dependency arrows cannot be dragged by user at run-time.

  16. It would be great if the borders around the charts had similar controls to that of CSS where we could edit the border colors and thicknesses individually. My one example is that we need to have only the left border of a chart thick red while the rest of the borders are to remain thin and gray. Here is an example image: http://connect.urnerbarry.com/public/album_photo/1d/09/0914_e1ba.PNG?c=332c

    There is an old idea that is similar but doesn't appear to have any replies other than mine here: http://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/4974960-can-we-have-series-border-options-like-left-border

  17. Simple breaks may be quite confusing now because the reader of the chart has no indications of the occurrence of a break in the axis. It would be very nice to add to the simple break an axis cut by too slashes same way as shown on the Y axis of this sample : http://jsfiddle.net/gh/get/jquery/2/highcharts/highcharts/tree/master/samples/highcharts/axisbreak/break-visualized/

    It would be very nice to have such feature configurable through highcharts editor

    visualization of the break in the graph itself is a more advanced feature that could be addressed in javascript because it depends much on the type of graph.

    Yes I agree this should be the default visualization. We need an option to turn it on or off though, as it would probably become too obtrusive for stock chart x axes where there is a break every night. Also, the Y axis by default has no line width, so the break by default would be invisible.

    Any suggestions?

  18. Being able to configure not just the fill colour of the bars in a chart, but the outline colour as well.

  19. Idea is shown here: http://waszczyk.com/resources/rectandleDoNotDelete.PNG Top edge indicates a maximum from chart and bottom edge shows a minimum with respect to input- T1 and T2. The background color is faded and custimizable.

  20. We have a requirement to color the bubble depends on the size. Basically, if the value is high, it will have a darker color and for a low value, a lighter color.
