  1. Hide tooltips when dragging on a chart to perform a zoom

    When dragging on a chart to perform a zoom, hide any showing tooltips as they cover up the dragged area and make it difficult to see what area you are selecting for your zoom.

  2. Animate chart when showing fewer data points to be consistent

    Currently if you add more data points and correspondingly increase the categories you get an animated transition. This does not happen however when you reduce the data points and categories. http://jsfiddle.net/mEFv7/1/

    To be consistent, can we please animate both ways.

  5. modify NumberFormat/DateFormat globally

    As far as I've understand the src of the highcharts, there is no way to change the internal functions defined inside the closure, unless you edit the source file.
    but the ability to alter NumberFormat/DateFormat functions (e.g. change number digits from english to arabic everywhere in the chart) is very needed for i18n.
    is there any plan for supporting this?

  6. Master detail chart with irregular interval

    I am not sure if this is already there. I just want to do a master detail chart where time can be at irregular interval and nothing is hard coded in the chart. I got a array of (Epoch time, value) pairs and everything drives from it. Any suggestions ?

  7. get the mouse position on the chart

    as you can see at http://www.flotcharts.org/flot/examples/interacting/index.html
    (hover your mouse on the graph and look at bottom: show mouse position)
    you can have mouse coordinates on the graph,

    today in highcharts i can only have the mouse coordinates on points,

    but i want to have a feature that can allow to get the coordinates of the mouse independently of the drawed points.

    it would be great!

  11. Set <svg> shape rendering property

    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

  12. Add delayed draw of legend (after graph animation is complete) please.....

    As of now the legend is displayed immediately (while the graph is still being drawn/anuimated). The idea is to delay drawing of the legend until the graph has completed animatino...

  13. Add Print and Export events handler

    It'd be useful to have access to some more events, specifically I was thinking about 4 new events which could be captured and managed by dedicated handlers: onStartPrint, onFinishPrint, onStartExport and onFinishExport

    The first two are related to the act of printing the chart via the print button, the other two are related to chart exporting.

  14. Show value on top of plotline or allow multiple labels on a plotline

    Plotlines are excellent to point out interesting Things in the chart. With large datasets it can be a good thing to be able to have an additional label for the exact value of that plotline

  15. Panes should have individual colors

    Currently multiple panes could have individual colors on each alternate grid row via setting "alternateGridColor". Well that's the half! To see on
    http://jsfiddle.net/6AxvV/1/

    A new option "GridColor" should set the color of all grid rows of a pane. The option "alternateGridColor" shall remain unaffected.

  17. Support more intuitive legend customization - (maxHeight/navigation issue)

    Namely, I have an issue with the misleading maxHeight property. If you are digging deep enough in the docs to customize the legend to use maxHeight, this property's value should be taken as gospel.
    Either that or allow for the navigation (pagination) of the legend to be disabled without having to have useHTML enabled.

  18. Allow tooltip toggling

    In current version this scenario is impossible:
    1) load data
    2) zoom in
    3) enable tooltip (whatever that means programmatically - now basically deleting the charts element and constructing new, then zooming in with setExtremes)
    4) zoom out to the full range previously loaded (that is what's now impossible)

    In my current project I run into this scenario quite often.

    And, by the way, the Highcharts library is really good, tank you for the job well done!

  19. Add HighCharts to packagist so that it can be managed with composer as a dependency

    HighCharts is not found on packagist. So it would be nice to have it added there. Managing the dependencies with composer is so much nicer and cleaner. Thanks.

  20. Multicharts with sliders showing values on all charts as per WeatherUnderground Beta Weather Site.

    WeatherUnderground's new beta weather site (http://preview.wunderground.com/cgi-bin/findweather/hdfForecast?query=94965&MR=1) shows the use of three charts showing various weather variables with ONE slider over all three charts showing the values on all three charts. This multi-layered configuration of charts linked by one slider would definitely be great indeed as it avoids crowding too may items on one chart.
