  1. Able to add a tooltip positioner to a specific dataseries

    I would like to be able to add a tooltip positioner function to a specific dataseries. Now I have to go via the tooltip object which affects all tooltip positioning. Lets say I want a custom positioner for the main dataseries but another, or the default for tooltips connected to my flags.

  2. X and Y Error bar

    At the moment X axis error bar and y axis errorbar( using inverted option) are available.
    It would be great to add the ability to have them both together in the same chart.
    Example: http://www.jfree.org/jfreechart/api/javadoc/images/XYErrorRendererSample.png

  6. add a option flag to disable the legend handleOverflow function call

    When I export the svg to pdf with option "useHTML", it returns blank legends.
    So I suggest to add an option flag to disable the legend handleOverflow function call

    if (! this.options.disableLegendOverflow){
    legendHeight = legend.handleOverflow(legendHeight);
    }

  8. Hide overlapping pie labels

    If pie labels are long and positioned inside (distance < 0), they overlap. It would be nice to have an option to hide some of the labels.

    I understand this is the same problem as finding the maximal independent set in a graph where the nodes are the labels and they're connected if they intersect.
    That's an NP-hard problem: http://en.wikipedia.org/wiki/Independent_set_(graph_theory)#Exact_algorithms

    It would be nice to have a simple approximation algorithm.
    I have been experimenting with this: http://jsfiddle.net/yf2MA/

  10. Sorted Scatter Plots

    Add a "sorted" option to scatter plots that allow marking data as sorted or not ( defaulting to false ). This way, when there is a large number of scatter points, we can get the sorted performance enhancements but still get the scatter functionality ( for example, a line plot with a hidden line still has the tooltip jumping around on the invisible line ).

  11. Static image rendering for performance

    The dynamic SVG plots could be replaced by a static image of the plots, similar to how the exported PNG looks. The choice between dynamic and static could be made at runtime based on the size of the dataset.

    I'm generating scatter plots based on data from a database. The plots looks great, however the performance gets to be a probably when the plot has more than 1000 points.

  12. Add an event for legend item hovering

    You might add mouseover/mouseout events to legend items. This event should provide the index of the legend item.

    That gives the developer more control about what to do when hovering legend items and gives him the control to devide whether a tooltip should be shown or the series should be highlighted or whatever.

    A common use case might be to show tooltips when hovering legend items --> http://jsfiddle.net/ArmRM/481/

  13. Sort the legend

    Right now it looks alphabetical in the legend even though the data shows by yAxis in the graph. Sorting would help with turning plots on or off.

  14. Can we have a timeline chart which is absolutely business oriented

    Can we have a timeline chart which is absolutely business oriented? Basically Business team here at my organisation would like to visualize charts based on fiscal year instead of calendar year. For example
    i. Fiscal year starts on 1st of July every year.
    ii. Aggregating data based on Fiscal quarters
    iii. Flexibility for aggregating week data as per the selected day(In our case we aggregated week data from Saturday to Friday)
    iv. Formatting x-axis labels as Fiscal years/ Quarters/ Months/ Weeks not just calendar year/ month / week

  16. Enhance legend positioning

    Now legend positioning is automtical and "horizontal first". I.e. when ALIGN:LEFT, legend space reserved on the left firstly and secondly I can vertically align the legend. Only center-aligned legend can be placed at bottom or top of plot area.

    But my designer want to have left-aligned legend at bottom.

    So it seems good idea to add legend option like
    position:={top|bottom|left|right} to specify where the legend space is reserved, and use existing align/verticalAlign options to align legend inside legend area. May be ignore verticalAlign property for top/bottom position (not sure) but apply both alignment for left/right legend.
