  1. Support value location for axis origin, see http://highslide.com/forum/viewtopic.php?f=9&t=15284

    Since now, if you want to specify X-axis origin for column chart, you can set offset value for X-axis. But this is not usable, the offset value is just absolute points, not actual Y value. I know many popular charts support using actual Y value as X-axis origin, this should be convenient for user to specify a relative X-axis location to Y axis.

  3. Allow the tooltip to appear when a point is clicked (instead of hover).

    Tool tip only appears when a point is clicked rather than hover. The tool tip would persist until another point is clicked or if the user clicks anywhere on the chart.

  5. Support HTML name/number entities in text returned by tooltip.formatter

    The tooltip.formatter() supports some HTML entities, e.g. <b>, but it doesn't support named or numbered entities.
    For example, if I return "&deg" the tooltip shows those 5 chars instead of the degrees mark(°).
    Same if I return "°"... tooltip shows those 6 chars instead of the degree mark.

  6. Prevent the cursor from chaging to an I-beam when mouseover text (eg: axis labels)

    By adding the pointer-events="none" attribute to the chart's <text> elements you can cause the cursor to NOT change to the I-beam when the user mouses over stuff like axis labels and such.
    Little stuff likis GREATLY improves the professional appearance of the chart.

  8. add category label mouse events

    Events triggered when a user clicks/hovers/etc a category label (xAxis labels).

    I would use this to provide more in depth information about the label clicked. For instance, charting years in xAxis, user clicks 2012, should bring up a menu with additional options for that year

  9. Crosshair snapping

    When I move my mouse ("zoomType=x" enabled chart) over the data, the x-crosshair seems to snap to the datapoints. there should be a way to either:

    1. turn off the "auto-snapping" function
    2. disable/hide the "x-crosshair" when a "zoomSelection" or "mousedown" event takes place and then enable/show it after a "mouseup"?
    3. snap the "selection start/end" to the "snapped-datapoint"

    Any one of these solutions or any other suggestion would be great!

  11. Add flag text to the main tooltip when aligned with the flag's date.

    When i have one or more flags on highstock, i'd like the flag's text will show up in the tooltip that shows up on the charts itself and not only when pointing on the flag

  12. multiple axis alignment control

    There seems to be a lot of posts in the forum asking how to align the 0 values of multiple y axes.

    My thoughts for implementing this:
    Chart level option (like alignTicks): alignBaseline: boolean (default: true)
    Axis level option: baseline:(numeric) (default: 0)

    By default 0 is the baseline for each axis, and by default the 0 value for each axis is aligned.
    The user can set the baseline to any other set of numbers that should be aligned, or turn off alignment.

  13. Don't draw chart / series if set of data is empty.

    Currently I have an issue where if a set is empty, the line will still be displayed, and if all of the series are empty, a chart will display without any lines. This should be handled by default where if the series is empty, do not draw the line for it, and if all of the series are empty, do not draw the chart.

  14. add support for subscripts and superscripts to the Renderer buildText function.

    Currently, the buildText function doesn't render subscripts and superscripts in the SVG output, but subscripts and superscripts are supported in SVG 1.1 using the baseline-shift attribute on the tspan element. Please add support for parsing <sub> and <sup> tags and rendering them as appropriate tspan elements.

  15. define the height of xAxis plotBands or a widht of yAxis plotBands

    I need to define specific areas in my scatterplot.
    It would be very helpful to have the possibility of specifying y limits for a band plotted on the x axis and the other way round (that is to specify x limits for a band plotted on the y axis) in such a way that someone can highlight delimited areas (in the form of a rectangle).
    Thank you!

  20. Use requestAnimationFrame instead of setTimeout

    All animations in Highcharts use setTimeout. A new feature, requestAnimationFrame (https://developer.mozilla.org/en/DOM/window.mozRequestAnimationFrame) optimize all animations (CSS3, SVG, JS) to have a smooth rendering.

    More explanation : http://paulirish.com/2011/requestanimationframe-for-smart-animating/
