        • Add Custom Buttons

          Include options to set up custom buttons with call-backs to perform certain functionality.

          For example, I would love to be able to have a button next to the current print and export buttons that would be used for help/information about the chart.

              • 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.

                • Crop / Flow Plot Band Titles

                  If you have a band title that exceeds the width of the band it currently overflows in unattractive ways. It would be nice if there were a few options for situations where the title exceeds the width of a plot band like:

                  - Crop (with optional center, left, right, alignments)
                  - Warp
                  - Ellipses
                  - Hide
                  - Bleed into neighboring plot bands (the current behavior that may not ALWAYS be undesirable)

                  • HighStock support for several date format such as decimal year (UTC) or Julian date

                    It would be very convenient to pass several date formats to HighStock and use the scroll/zoom functionalities with those dates (without any transformation in UTC day-month-year-hour:min:sec).

                    For instance, astronomers use large time series but dates are usually formatted in "Julian Days", "Modified Julian Days" or Decimal Years (UTC) which are all double numbers. It would be nice to be able to see those values on the X-axis keeping the scroll/zoom functionalities.

                    UTC decimal years Ex : Date=[2012.345643, 2012.35432,2012.37234, etc...]
                    or
                    Julian dates Ex : [2456342.7345,2456342.7845,etc....]
                    or
                    modified Julian dates : Ex : [56342.2345,56342.2845,etc....]

                    • Shared horizontal crosshairs

                      When using a shared tooltip and horizontal crosshairs, the crosshair will only display on the first series drawn, if there is more than one. Even if the cursor starts out tracing along a different series, the crosshair is pinned to the first series drawn. Could this behaviour be modified so the crosshair is associated with the series the cursor is highlighting?

                      • Step line that draws leading or following part

                        Currently, I can use a step line to draw non-continuous data. However, the rendering of the first or last data points in a series does not show the leading or following horizontal data line.

                        For example, the last data point in the first series represents the data from Apr to May. However, the rendering makes it seem like it's only data for Apr and that there's a gap in data between Apr and May.

                          • Color blind readability.

                            Support background textures on solid color UI elements like Pie and Bar charts.

                            Ideal solution would be angled lines in the charts for example http://www.inetsoft.com/images/screenshots/controlling_texture_in_a_bar_chart.gif

                            • HighStock Navigator as a standalone component.

                              Hi,

                              Please make HighStock navigator a standalone component.

                              It could have several usages besides driving the HighStock time:
                              - immediate time selection/change for any web application - much more intuitive than just a Date + Time picker. Right now there's nothing similar: you have it, it's user friendly, but it' just not standalone.
                              - use to zoom in and out several HighCharts (not HighStock) in the same page. Right now there's only a mouse based zoom (with and selection), but that's not very efficient when using more than one chart in the same page. Syncing those charts is still not…

                                    • multiple chart export

                                      It would be really great to be able to export multiple charts to a single image

                                      • Better Performance - Provide jqmobi (Intel AppFramework) adapter

                                        Problems:
                                        1. Highcharts is awesome, but consumes too much of resources on less performant systems
                                        2. jQMobi is fast, building Apps with jQUI a joy, but getting it to live in harmony with Highcharts + jQuery on the same page can become quite a hassle and re-introduces the (comparably slow) jQuery into your app.

                                        Having a jqmobi adapter would be great.

                                        See https://github.com/01org/appframework for jqmobi reference and code.

                                        • Create some form of tree / node linking chart

                                          Highcharts doesn't currently appear to have any tree / node linking chart types. A few examples would be:

                                          - Dendograms: https://en.wikipedia.org/wiki/Dendrogram
                                          - Hierarchical clustering: https://en.wikipedia.org/wiki/Hierarchical_clustering
                                          - Minimum Spanning Tree: https://en.wikipedia.org/wiki/Minimum_spanning_tree

                                          The above chart types vary in their purpose and how they are constructed. But this request is simply to have some form of tree / node linking chart capabilities in highcharts.

                                          Once it becomes possible to chart a basic tree or hierarchy structure, it may be easier to extend functionality to create further chart types along the same thinking.

                                          Plot.ly currently offers both dendrogram's and tree plots within their python…
