  1. 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.

  2. We have a requirement to generate Smith Charts. Can Highcharts support Smith Charts?

  3. A chord diagram or an extended diagram is basically used to show data flow between multiple entities. We can have a circular chord diagram or an extended one.
    Currently we are achieving it through d3.js, but that requires lot of complex coding

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

  7. 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?

  8. Scatter and bubble charts do not seem to support collision avoidance for data labels. Along with collision avoidance, connectors that link the points to the data labels would be very helpful.

    Thank you for the great library.

  9. PhantomJS/HighCharts at the moment supports only chart by chart server side image generation by passing options of a chart.

    It would be nice that when someone passes multiple options PhantomJS and HighCharts consider this as each option as a new chart and stack them together into one image.

    Only solution at the moment is that we generate one by one chart and combine them seperetly which i think should be done already on PhantomJS/HighCharts.

  10. I would like the option to show a the numbers for a single data point and its associated margin of error (M.o.E.) bar in a single unified tooltip, as in:

    [ Apples: 67.5 (M.o.E.: 63.4 - 71.6) ]

    I would like this rather than having the data points and margins of error on separate tooltips or having data for all series on the same shared tooltip.

  11. 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.

  12. If you have a chart such as the following: https://s3.postimg.org/juxazrv5f/Screen_Shot_2016_08_19_at_20_19_08.png
    And you change that yaxis 0 value to non-zero, i.e. 10, then the following occurs: https://s3.postimg.org/jdop36c8z/Screen_Shot_2016_08_19_at_20_18_27.png

    We urgently need a hack/workaround to once again display the rounded corners. We are using Torsteins rounded-corners plugin to achieve this.

  13. Highcharts doesn't currently appear to have any tree / node linking chart types. A few examples would be:

    The above chart types vary in their purpose and how they are constructed. But this request is simply to have some form of tree / node linking chart capabilities in highcharts.

    Once it becomes possible to chart a basic tree or hierarchy structure, it may be easier to extend functionality to create further chart types along the same thinking.

    Plot.ly currently offers both dendrogram's and tree plots within their python API. But of…

  15. When plotting a plodBand it doesn't plot the top border, if it's required to not plot the top border for some use cases, there should be an option to plot or not the top border.

  16. 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.

    Hi, this feature is prevented in two places, because there were problems with text being selected when trying to zoom in. See https://github.com/highcharts/highcharts/issues/3224.

    If you want to enable text selection, there are two lines where the event handling is prevented. If you comment out both these lines, your users can select text:

    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L756
    - https://github.com/highcharts/highcharts/blob/v5.0.14/js/parts/Pointer.js#L813
