1. callback for 'noData'

   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.

   Thanks for your suggestion! You can wrap the showNoData and hideNoData functions to add your custom code: http://jsfiddle.net/highcharts/3u2crb53/

2. Faded rectangle on candlestick chart which indicates minimum and maximum based on time t1- begin and t2-end of time window.

   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.

3. chart.options.zoomed parameter

   In some cases I would like to know from outside the chart if the chart is in a zoomed in status or not without having to record initial state and later compare. This should be quite easy to do internally as you are already monitor this status for the "reset zoom" button.

   The simples test would be to look for the button:

   if (chart.resetZoomButton) {
   // doSomething();
   }

4. Create a way to add benchmarks to individual columns

   This would be similar to plot lines except it would be a line against which each column would be compared to, similar to this image: http://i.stack.imgur.com/NOWBk.gif

   It has been suggested by Highcharts staff on StackOverflow community to use a scatter series with a custom shape for the line, which would work fine. But I wonder if this is a standard enough feature on a column chart to be worth supporting in a more "native" way.

5. Tooltip: Would like all column ranges in a series to be highlighted when mouse hovers on one element

   I wish there is a way to load images so I can show you a screenshot. Now I'll try to describe it: Say Joe and Bob eat fruit apple and pear and Joe's consumption is green colored. I want the tooltip to do this: When the mouse is placed on Joe's share (a green area) in either apple or pear category, the tooltip shows Joe's consumption of apples AND pears (like apples: 2, pears: 5). That's easy using the "formatter". However, I also want Joe's shares (the green areas) in BOTH apple and pear categories to be highlighted. Currently, only the green area under the mouse is highlighted.

6. Force pie chart dataLabels to be within chart bounds

   force all pie chart data labels to be within the bounds of the container. For example if you want to offset the pie chart the labels will stay within the bounds of the container and not get pushed out of the viewing area. Or be a be able to set the location on the pie slice that the label is pointing at.

8. Output format of eps or emf added

   Printable documents benefit from vector based images. For example when embedding an image in word or powerpoint it would be more useful to have emf or eps charts than png. Unfortunately svg is not support by most non-browser software.

   Is it possible to add eps or emf output to the list of available formats?

   If you can host your own export server, there would be a technical possibility of converting generated PDFs or SVGs in to those formats. I think that is the best chance.

10. Prepacked Export server

    We would like to use the Export server and it would be much easier to get sign off to use it, if it were a pre packaged appliance, i.e. an OVF etc tht can be loaded up in VMWare. the appliance could carry a same support fee for upgrades to the OS, prerequisites and Export server itself. finally a support option could be added

11. Allow datetime axis labels to use guessed tooltip date format

    With bigger time series data the x axis may have labels like 2012, 2013, 2014,... while the tooltips display January 2012, February 2013, since this is the actual data spacing. I think it is sometimes confusing to have those two different date formats and it would be nice to be able to specify that the datetime axis labels should also the same guessed date format as the tooltip.

    I currently work around this with:

    var xAxis = chart.xAxis[0]
    var labelConfig = chart.series[0].points[0]
    var guessedTooltipDateFormat = chart.tooltip.getXDateFormat(labelConfig, labelConfig.series.tooltipOptions, xAxis)
    xAxis.update({labels: {format: '{value:' + guessedTooltipDateFormat + '}'}})

    Currently the axis and the points live separate lives in a datetime axis, because we don’t necessarily want a one-to-one match. See for example http://jsfiddle.net/13tbwp3j/, where one axis tick per point would result in a cluttered axis.

12. Pie label distance as percentage of pie size

    Allow percentage value for option dataLabels.distance (percentage of the pie radius). That way I can make sure that the labels fit inside their slice for every label length and pie size.
    http://jsfiddle.net/kzoon/ntDX9/ shows what I mean. If you use distance -30 longer datalabels go outside their slide. If you use -50 they fit, but that will mess up small pies (100px).

14. Explicit support for drill-down Ajax interactive data zooming

    I have an extremely large dataset (once-a-second measurements extending over several years) that I'd like to be able to zoom in (and out) interactively with the Highstock navigator as well as direct selection with the mouse.

    I think I have finally managed to piece together a somewhat stable solution by using the rather under-documented setExtremes event. However, some slight instabilities remain, mainly due to the fact that the setData method appears to itself trigger the setExtremes event sometimes. In addition, my dataset is discontiguous (has many gaps) and Highchart seems to like to shrink the limits of the selected data range to exclude gaps surrounding the data, which also ends up triggering setExtremes again.

    So, since such interactive Ajax behavior seems to still be in the experimental phase, I'd like to cast my vote for it becoming an official feature.

    Based on my experience working with the tool over the last couple days, I've arrived at the following approach which could work so much better if Highcharts somehow better supported this, probably through explicit events tailored to dynamically populating data interactively.

    1. My external server-side script has two distinct modes-

    (a) give me all the data, averaged by hour. This gives me on the order of 10,000 points, which is very doable to work with to populate the navigator series and provide interactivity with a good range of zoom levels.

    (b) give me a date range of data in full, down to the second. This I use for data ranges less than 24 hours long, This gives me no more than 86,400 points, which is doable especially because the user is expecting a delay (and I show the "loading" display).

    1. My client-side Javascript, which uses Highstock, initially reads in all the data by hour and explicitly populates the navigator with it, as well as the main chart.

    2. I hook into the setExtremes event of the xAxis, and if the selected date range is 24 hours or less, I retrieve just that data and use setData to apply it to the series of the main chart. If the selected date range is greater than 24 hours, I simply setData back to the original full series, which is still in memory and in use by the navigator.

    The problems are mainly that the setExtremes event tends to get triggered multiple times per user interaction, particularly when the navigator is manipulated by the user. So, I have to put in an explicit test to make sure that the min and max passed directly in the event object are in fact different than the current min and max, which I obtain from the currentTarget property of the event object. If I don't test for it, an endless loop often occurs because it appears that in some cases the setData method can trigger a setExtremes event itself.

    In addition, as I mentioned, the system seems to like to shrink the gaps between the data and the start of the date range, which can be disconcerting because, when zooming in on a particular "island" of data, it is useful to see the gaps so that you know you have all the data from that island in view, and that the edge didn't get chopped off.

    So, I think one approach to this could be the creation of a "getData" event, which would be triggered whenever the display range of the chart is changed - after the system has completely settled on exactly what the new range will be, but before it has attempted to update the display. This event would be triggered regardless of the source of the display change, whether it is programmatic, or through user manipulation of the navigator or direct selection of a subrange on the chart by click and drag.

    The event would be passed the exact date range (or more generally the xAxis range) that it intends to display. The user handler could choose to do nothing (the default), in which case the existing series data would be displayed. Or, the handler could fetch new data into one or more series' data range(s). The Highchart system would then, upon completion of the getData event, display exactly the xAxis data range it had passed to the getData event, possibly adjusting the yAxis to conform to the new data depending on settings related to yAxis behavior.

    This event, in my vision of things, would not have the ability to change the xAxis range that is to be displayed, nor could the system "change its mind" and make adjustments to the range being displayed after the getData event is triggered. This is important because the user will then experience a stable environment in which what they select with the mouse is what they get, no matter what the data looks like, or what gaps are in it.

    From my testing, no event exists that satisfies this criteria. The redraw event comes close, but it is not always consistently triggered, particularly when the Highstock navigator is used. The setExtremes event comes closer, but it exhibits the instabilities I have discussed, that I had to work around. setExtremes appears to be triggered too "early" in the process, so to speak.

    If there is a way to accomplish exactly what I have proposed using existing features of Highchart/Highstock, please enlighten me. Otherwise, my feature request is respectfully submitted.

    Thanks!

    [note: I have at least one other request that is related but I will submit separately.]

20. Area Range with 'flipping colors' after lines cross

    I have implemented the AreaRange a few days ago and the result is great, you can see an example here: http://buijten.fr/HighchartWithAreaRange.PNG
    It would be great to have two additional functionalities with this feature:
    - Having different fill colors when the range lines flip, as per this example: http://buijten.fr/ichimoku-example.PNG
    - Different line colors for the range limits (though this is achievable by adding additional lines as I did in the example)
