Exporting to a PDF-file offers a lot of benefits: you can share that file with colleges and customers not having access to JIRA.
Beside this, you can print the Gantt-Chart as large poster: just open the file within Adobe Acrobat Reader DC, click on 'print' to open the print panel as shown on the right and enable 'POSTER' for multi-page printing.
In case of very large Gantt diagrams containing a lot of issues, your browser's memory may be too small to handle the PDF creation properly. If you are using Firefox, then please re-try using Chrome which can handle larger files. Otherwise, please use the SVG-format which is often 15 times smaller.
Scalable Vector Graphic
SVG is an XML-based vector image format for two-dimensional graphics. As XML files, SVG images can be created and edited with any text editor. Because SVG images are defined in XML format, they can be easily searched, indexed, scripted, and compressed.
All major modern web browsers — including Mozilla Firefox, Internet Explorer, Google Chrome, Opera, Safari, and Microsoft Edge — have at least some degree of SVG rendering support.
For editing and further processing, the use of the free open-source product INKSCAPE is recommended being available for Mircosoft Windows as well as Apple OSX and GNU/Linux.
Microsoft Office 2016 added support for importing and editing SVG images in January 2017.
Due to best compatibility, the common file format XLS is used instead of the newer XSLX. Alternative spread-sheet applications like "Numbers", (c) by Apple Inc., are also able to open such files. The exported columns are statically defined by the add-on and do not take care about the configured columns by the user. Within future versions, this may change. Timelines cannot be represented within Excel in a suitable way, so that all necessary raw data are exported.
Most features are identical, but quite a lot of are different: e.g. JIRA issues can only be assigned to one user whereas MS-Project allows assignment to multiple resources, a summary task within JIRA may have got its own estimated efforts etc.
Each project task gets a hyperlink to its related JIRA issue. Additionally, you'll find a note per task containing the JIRA assignee and completion in percent (JIRA internal information), which you may not want to display to customers directly.
Microsoft Project can read/write XML files since 2002: that XML-based data interchange format (MSPDI) is used for simplicity as well as human readability in case of checking data, here.
Search and mark that issues on current Gantt-Chart
Having enabled EDIT mode, you can use drag'n drop to move/shift the complete Gantt bar or resize it by dragging the left or right end. Additionally, you can add dependencies: click on the blue bubble of the source Gantt bar, move the mouse over the target Gantt bar and click on the related blue target bubble to link. Available link dependencies are "finish-start", "finish-finish", "start-start" and "start-finish". If re-scheduling is enabled for this project, dependent issues will be automatically re-scheduled.
If EDIT mode has been enabled, you can also move the mouse over any field on the left side of the Gantt diagram to interactively edit that field content. But not all fields are editable like calculated fields or time-tracking information. During presentations, this edit pop-ups may be not suitable: just click on the EDIT mode to toggle into disabled status.
Please click on the EDIT mode button on the top right as display above to toggle edit mode or click on the button "Enable EDIT mode" below.
