One of OnePager's most powerful features is its ability to combine multiple project plans into a single timeline or Gantt Chart that spans your entire portfolio. OnePager enables you to build multi-project timelines from any single data source (Project, Project Online, Smartsheet, Primavera P6, etc.).
OnePager can also import a master project summary from Microsoft Project, Primavera P6, or Smartsheet if you prefer that over importing several projects individually.
Multi-Project Timeline
With a multi-project timeline, OnePager makes a single row for each separate project, and lines all tasks and milestones for that project up left-to-right.
Multi-Project Gantt Chart
For a multi-project Gantt chart, each task or milestone is shown in its own row, but then all rows for a given project are grouped together into a swimlane.
