Smartsheet Gantt Chart with Dependencies

Create a project Gantt chart from Smartsheet that shows the dependencies between each task and milestone.

Smartsheet lets you create dependencies between predecessor and successor tasks. OnePager can import these dependencies and display them on a Gantt chart so that it's easy to visualize the structure of your project.

OnePager is Gantt chart software for Smartsheet that also displays dependencies. Don't have OnePager yet? You can download a free trial and try it out today.

  1. Start with a Smartsheet project. In this example, we are using Smartsheet's Predecessors column to define dependencies between tasks and milestones:

    Smartsheet project with predecessors and successors.

    Most dependencies in this Smartsheet project are Finish-to-Start, but a few of the dependencies are Finish-to-Finish. Most of the tasks in this Smartsheet project only depend on one task, but some tasks have multiple dependencies.

  2. In this example, we'll bring in the child rows from Smartsheet, and will use the parent rows to group our swimlanes. We can create a filter using a checkbox column. Right-click and go to Insert Column Left. Then add a Checkbox column called OnePager:

    Add a checkbox column to Smartsheet.

  3. Now, we can check the box next to any tasks that we want to import into our Gantt chart:

    Filter your Smartsheet project.

    Save your Smartsheet project when you are finished selecting rows.

  4. When you are ready to start building your Gantt chart with dependencies, double-click the OnePager icon on your desktop. From the Start screen that appears, choose New.

    OnePager Bundle Start screen.

  5. On the import wizard, go to Select > Browse Smartsheet:

    Import dependencies from Smartsheet.

    If this is your first time using OnePager with Smartsheet, you'll be asked to log into your Smartsheet account.

  6. Select your Smartsheet project from the list that appears and click OK:

    Select your Smartsheet project.

  7. Give your Gantt chart a name, and tell OnePager to filter based on the checkbox field that you set up back in Smartsheet:

  8. Click Next followed by Create New Chart. OnePager will import your selected rows from Smartsheet and create a Gantt chart like this:

  9. Now, we need to import the dependencies from Smartsheet and display them on the Gantt chart. Go to Home > Chart Properties > Task Links and turn on the setting to Show Data-Driven Task Links:

    Import all dependencies from Smartsheet into your Gantt chart.

  10. Click OK, and OnePager will import the dependencies from Smartsheet and draw them on the Gantt chart, so that it's clear where there are predecessor-successor relationships:

  11. This is starting to look pretty good, but you may want to clean up your dependencies a little so that they're easier to see. You can click on any dependency with your mouse and use the handlebars to change its path:

    Change the path of any Smartsheet dependencies in your Gantt chart

    You can also move text out of the way, or increase the height of your rows to improve the look of your Smartsheet dependencies.

  12. After a few adjustments to the dependency paths and task text, we end up with a Gantt chart that clearly shows each dependency from Smartsheet:
