How to show dependencies between tasks

OnePager lets you create Task Links, previously called Event Links, to show dependencies (predecessor or successor relationships) between two tasks or milestones in your Chart. There are two main ways to create these links:

Data-Driven Links

OnePager has the ability to dynamically import predecessor and successor data from Microsoft Project, Planisware Enterprise, Primavera P6, Smartsheet, Asana,, Wrike, or Excel. This way, as your dependencies change in your project plan, OnePager can track and update them automatically. Here's how:

  1. Go to Home > Chart Properties > Task Links

  2. Microsoft Project, Smartsheet, Planisware Enterprise, Primavera P6, Asana, or Wrike Users: Check the box to Import and show links and click OK:

    OnePager will automatically import the dependencies from your project plan.

  3. Excel Users: Check the box to Import and show links. Then, specify which Excel field you want to use for your links, plus whether your dependencies use Microsoft Project or Primavera P6 syntax before clicking OK.

Manual Links

To link tasks or milestones manually:

  1. Hold down the Ctrl key on your keyboard.

  2. Left-click on the two related tasks or milestones. You can also select a larger series of tasks to link all at once.

  3. Go to Insert > Task Link to establish the link.

You can now double-click on the event link to change its formatting. Once established, an event link will remain in a Chart until you say otherwise. If you add a new snapshot to your Chart with different dates for related tasks, the event link will auto-adjust to accommodate the schedule change.

You may find that after importing predecessor or successor data from your project plan that there are too many links, and that you want to filter them down to improve readability. To do this, please read our article on filtering task links.
