Gantt Chart by SmartVisuals
by SmartVisuals.io
Project timelines with CPM critical path and float, slip against baseline and schedule health.
Gantt Chart by SmartVisuals turns a Power BI table into a project schedule you can steer. Build the timeline with a collapsible work-breakdown hierarchy and rollup bars for free, then see what drives your finish date: the critical path by CPM with float on every task, the slip against the plan drawn on the bars, and a schedule health strip that sums it all up.
Everything is computed locally inside Power BI. No external services, no API keys, no data leaving your report. Certified by Microsoft.
Free for every viewer
- Work-breakdown hierarchy from a Parent Task field, with rollup summary bars, collapse and expand, and one-click collapse all.
- Milestones, progress and overdue marks (progress as 0-1 or 0-100, detected automatically), a today line and two reference date lines for deadlines or a data date.
- Calendar-aligned time axis with fit, day, week and month zoom and sticky headers.
- Four themes, report-theme colors, bar and milestone styles, conditional bar colors (fx), a legend with position and title, and on-object formatting.
- Model formats including dynamic format strings, rich tooltips with report-page tooltips, cross-filtering (a summary bar selects its whole phase) and keyboard navigation.
- 20 languages and large plans loaded in segments, up to 5,000 tasks.
Premium: schedule control
Per-user license, first month free.
- Critical path by CPM - a real forward and backward pass over your dependencies and dates. Float bars show how many days each task can slip before the finish moves, near-critical tasks are outlined, and the tooltip gives total float, free float and the late finish.
- Slip on the bars - add Baseline Start and End: the plan sits under each bar, the part past the planned end turns into a hatched red tail and every late task carries a +days chip.
- Schedule health strip - late tasks, actual vs planned progress, slipping tasks and the finish slip, critical and near-critical counts, and how far the links themselves move the finish.
- Dependency arrows - finish-to-start connectors from one comma-separated predecessor field. No relationship table to model.
- Grid columns - up to three sortable columns beside the task names (Owner, Status, Cost...), with sums on summary rows.
How licensing works
Everything is unlocked while you author or edit a report, so you can build and test the full chart before deciding. Free features always render for every viewer, and the visual never blocks your report or shows a watermark. A per-user license is only needed to see premium features in reading view. Licenses are purchased through AppSource and assigned in the Microsoft 365 admin center. Additional purchases may be required.
New in 1.1: CPM critical path with float, slip on the bars, the schedule health strip, on-object formatting, fx colors, reference lines and 20 languages. Reports built with 1.0 keep their look until you switch the new options on.
Getting started
Drop in Task, Start Date and End Date and you have a working chart. Add Parent Task for the hierarchy, Dependencies for arrows and the critical path, Baseline Start/End for slip, and Progress %, Category, Grid Columns or Tooltips as your project needs them. A task with the same start and end date is a milestone.
Made for construction schedules, product roadmaps, implementation plans, campaign calendars and portfolio timelines.
