When line chart is added data will be on the right and the chart is a long as the selected period.

It would be really nice If I could use entity values to defined chart start and end. Use cases that I have current that would benefit the feature:

* Show the number of open tasks in and JIRA EPIC in a line chart where chart length is the start and end date of the EPIC at hand.

* Display service tasks sprint progress in a line chart so chart start from spring day 0 and ends sprint day X. Sprint start and end are in this case fields in the service entity.
