It would be nice if Timeline Charts allowed for the start and end date settings to be dynamic (or assigned to a line item). Currently, you have to choose a start and end date when you create a timeline chart, which effectively limits the chart to your initial publication. For example, if you are using a timeline chart to display the timelines of multiple projects (with Synchronized Paging selected for your projects to allow the chart to update dynamically), you are stuck with whatever start/end dates you first selected. If one project starts in April and ends in June and another starts in September and ends in October, you cannot currently set the chart to start in April and end in June then dynamically update to September to October when you select the second project.
All other graphs update their axes automatically, so why should the timeline chart be any different?
