Timeline

Plot records across date ranges, adjust their timing, and zoom from days to years.

Use a timeline to compare record schedules across a continuous date range and adjust start and end dates in place.

Understand a timeline

A timeline plots each record as a horizontal bar. The bar's position shows its start, and its width shows how long the record lasts.

You can build those bars from one date field that includes an end date, or from separate start and end date fields. A red vertical line marks today.

The Crew Schedule timeline spans August and September with scheduled project bars, a red today line, Month zoom, and a Today control.

Choose the timeline dates

Use one date field when that field already stores a date range. Use separate fields when your collection has distinct values such as Start date and `End date`.

Use one date field

  1. Open the view settings menu.
  2. Select Layout.
  3. Confirm that Timeline is selected.
  4. Turn off Separate start & end dates.
  5. Under Show timeline by, choose the date field.

The timeline uses the field's date as the beginning of the bar and its saved end date as the end.

Use separate start and end fields

  1. Open Layout for the timeline.
  2. Turn on Separate start & end dates.
  3. Under Start date, choose the field that begins the bar.
  4. Under End date, choose the field that ends it.

The timeline redraws using both fields.

Timeline layout settings use Start Date and Estimated End Date with Separate start and end dates enabled and Show table available.

Change the time scale

Use the zoom selector above the timeline to choose how much time each portion of the canvas represents:

  • Day
  • Week
  • Bi-week
  • Month
  • Quarter
  • Year

The timeline keeps the visible date near the center when you change zoom. Use the left and right arrows to move through the timeline, or select Today to return to the current date.

Add a scheduled record

The final row in each timeline section creates records.

  1. Move your pointer across the empty creation row.
  2. Position the preview bar on the date where the record should start.
  3. Select the canvas.
  4. Enter the record name.

Bidlo creates the record with dates based on the selected position and current zoom. If the name table is visible, you can also select New there to create a record beginning around today.

When the timeline is grouped, creating in a section also assigns that section's group value.

Move and resize a bar

Drag a bar left or right to move the full date range while keeping its duration.

To change only one edge:

  1. Hover over the bar.
  2. Drag the handle on the left edge to change the start.
  3. Drag the handle on the right edge to change the end.

A date tooltip follows the pointer while you drag. Bidlo prevents the start from moving after the end and the end from moving before the start.

Show the name table and fields

The name table keeps record names visible at the left of the timeline.

  • Select the table toggle above the timeline to Hide table or Show table.
  • Open the view settings and select Fields to control the information used by the record cards.
  • Turn Show page icon on or off in Layout.
  • Use Open page in to choose Side peek, Center peek, or Full page.

When a bar is outside the visible date range, an arrow appears at the edge of its row. Select the arrow to jump to that record's dates.

Group a timeline into sections

Use Group in the view settings to create timeline sections from a field. Each section keeps its own records and New row. Select a section heading to collapse or expand it.

Filters and sorts continue to control which records appear and how the rows are ordered. These settings affect this timeline without changing other views of the same collection.

FAQs

Why does a record have no timeline bar?

It needs a usable start date in the field selected for the timeline. Records without plotted dates can remain in the name table without a bar.

Does moving or resizing a bar update the record?

Yes. It changes the underlying date field or fields, and other views using those dates will reflect the change.
