      A demo of the current progress using the gantt-module can be viewed and played with here: http://jsfiddle.net/larsac07/ebprm9au/

      We are currently working on Gantt charts, including the following features:
      ​- Tasks (Activities) with task name, start- and end-dates
      ​- Milestones
      ​- Dependencies
      ​- Multiple tasks on a single y-value (X-range study: http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/studies/xrange-series/)
      - Subtasks: Treegrid for grouping tasks (unlimited levels)
      - Indicator for current date
      - Indicator for progress per task
      - Detailed datetime axis: Classic Gantt date axis, e.g. weeks and single-letter days / months and weeks etc.

      Release dates are not set, but features and modules have been defined, and development has started.

      We’re developing in modules, and gathering the modules into a gantt-module. Current modules which are in development include:
      - grid-axis (for making axes into a grid, and detailed datetime axis in a classic grid-like structure)
      - xrange (based on the study posted above, but including…

    • Autocalculation and plotting of trend lines

      Auto calculation and plotting of trend lines in line charts, as described at http://en.wikipedia.org/wiki/Trend_lines_(technical_analysis)

      • 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.

        • Stacked area (spline etc) in irregular datetime series

          When you create more datetime irregular series, by now only the same datetime values are used to create the stack, resulting in a correct-but-ugly graph.

              • toggle legend box

                if you can add a button which allows user to toggle the legend the it will be great, because as of now if you are displaying the legend on chart area then some part of chart points get hidden because of legend, and user just cant see them because legend box is on top of the chart points.

                I even tried to do a normal toggle action with help of jquery but there are some issues when we do it. e.g. if we hide the legend and then add some series dynamically to chart then series gets added properly but…

                • Venn Diagram

                  A Venn Diagram chart would be excellent. Nice and simple like the Google Charts API Venn, but with the usual HighCharts polish , tooltips, legends etc.

                  3 way would be great to start, 4 way even cooler ;-)

                        • grouped x-axis

                          Like Excel does when you use 2 columns for the labels.See example on http://minus.com/mHNwVqDZO.

                          Each item on the category axis falls in a group. The groups are displayed below the axis items. Each group name is displayed only once (centered below all its items). Groups are devided by longer tickmarks.
                          Each group can contain a different number of items.
                          Possible uses:
                          * display structured categories like product and product group or country and region
                          * display two or more groups side by side, like gross sales and net sales, or this year and last year.

                                  Panning and Zooming like in Google Maps is way nicer to use than the current implementation of rectangle zoom. Would be great to have such feature :)

                                    • Crossfilter

                                      Hi, wanna know if it's possible to add Crossfilter: http://square.github.com/crossfilter/ functionality in Highcharts.
                                      At this moment, samples of crossfilter are using d3.js .
                                      I'm using Highcharts because it's awesome BUT Crossfilter yet.
                                      Can someone help me about this, please ?
                                      Best regards.

                                      • data module for database tables

                                        data module was a great addition. have been using that pretty much everytime i can covert my data to csv.

                                        but having database module to load data from one table would be just awesome.

                                        • Draggable points

                                          Click and drag points on line charts and a correspoinding PointModified event so backend data can be updated.
                                          This will allow features to be built so users can modify data using the chart itself.
