Switch between the new and classic Gantt

All plansProject Member

Onplana has two Gantt charts. The new one is what everyone opens, and it is the one Plan on the Gantt chart describes. The classic chart is still there as a way out if the new one fails to load, and this page is about how you end up on one or the other.

Which one am I looking at?

Section titled “Which one am I looking at?”

Look at the toolbar above the chart:

  • View, Schedule, AI and Share menus, with a line such as “24 tasks” in the row above them, means you are on the new chart.
  • A Use the new Gantt button above the chart means you are on the classic one.

With the row of four views above the chart (Gantt, Task sheet, Resource sheet, Resource usage), the Task sheet is the new chart’s table on its own, so on the classic chart it shows the whole classic chart instead. See Task sheet, Resource sheet and Resource usage.

How someone ends up on the classic chart

Section titled “How someone ends up on the classic chart”

The new chart no longer carries a button to switch away. There are two ways a person is still on the classic chart:

  • The new chart failed to load for them, and they chose Back to the classic Gantt on the card that said so.
  • They switched back before mid-September 2026, when the new chart still had a switch above it.

The choice is stored in each person’s own browser, so nothing one person does moves anyone else, and no administrator sets it for the team.

Go back to the new chart

Section titled “Go back to the new chart”

  1. Open a project, open the Tasks tab, and choose Gantt.

  2. Select Use the new Gantt above the chart.

The chart is replaced immediately, and the choice is remembered for next time. Nothing about your project changes. Both charts read and write the same tasks, dates and dependencies, so switching is a change of view and never a change of plan.

If the new chart does not load

Section titled “If the new chart does not load”

You get a card saying so, with a Retry button and a Back to the classic Gantt button on the card itself. The second one puts you on a working chart immediately. Taking it also records the preference, so refresh and you are still on the classic chart, until you select Use the new Gantt again.

What the new chart adds

Section titled “What the new chart adds”

The short version, with the detail in Plan on the Gantt chart:

  • Edit in the task list. Names, both dates and hours are editable in place, one click to put the caret in the cell.
  • Add work without leaving the chart. A task or a subtask, from the toolbar, from the row you are looking at, or typed into the Add a task row.
  • Draw a dependency. Drag from the handle on one bar onto another and the link is saved.
  • Find and filter. Find a task by name, and filter by status, priority, people, tags, epic, sprint, dates, milestones, the critical path or overdue work.
  • Try a change first with What if…, and see why the finish date moved after an edit that moved it.
  • Undo the latest changes on the chart.
  • It counts what it cannot draw. The title row says how many tasks have no dates, with an Add dates link.
  • It opens at a sensible scale, chosen from how long your project runs rather than always starting at the same one.

What the classic chart does differently

Section titled “What the classic chart does differently”
  • Baselines are gray ghost bars. The classic chart draws a gray bar under each live bar where the baseline put it. The new chart marks each task that has moved with a chip, such as +3d, and draws a Baseline finish line.
  • It can hide subtasks in one click. The classic chart has a Show subtasks toggle. On the new chart subtasks are always present; collapse a parent, or use Collapse all in the toolbar.
  • It has none of the toolbar menus. Filtering, What if, the schedule quality flags, restoring a schedule and the AI menu are on the new chart only.

FAQs

Section titled “FAQs”

Is the classic chart going away? Not today, and not without notice. It is the fallback when the new chart has a problem, so it stays while that is still worth having.

Can an administrator put everyone on one chart? No. The preference is per person and per browser; there is no organization-wide setting for it. Everyone starts on the new chart.

Do I lose anything by switching? No. Both charts render the same project data. Your view settings inside a chart, such as the timescale and column widths, belong to that chart.

Which plans have this? Both charts are on every plan, Free included, along with the critical path, all four dependency types and the baseline overlay. See Compare plans and upgrade.
