The Timeline Panel

The Timeline is layered behind the Data Tables.

The Timeline shows aggregated data as a histogram over time, using the genomes' sample date (collection date or receipt date). This is NOT the upload date the genome was submitted to the PATH-SAFE platform, so it's different from the upload date used in Search filtering.

Note that the available options for granularity (e.g. down to the day) may not be relevant to all data. Genomes will sometimes only have "year" or "year/month" data (e.g. in PATH-SAFE collections).

Genomes with only a "year" will be shown in January of that year. Genomes with a "month" will be shown on the first day of that month.

Note for PATH-SAFE users: Saved Searches are generally configured to pull recently-added genomes, but those new genomes could be represented in the past on the Timeline, especially if they only have "year" data associated with them.

Anatomy of the Timeline Panel

A Filtered Timeline sits above a Timeline Overview.

The Filtered Timeline (top) shows the genomes per unit of time, coloured by the current Colour Column. The Filtered Timeline only shows the data within the selected timeframe.

Changing the date range on the Timeline acts as a filter across all panels.

The Timeline Overview (bottom) always shows the entire date range of the data in the Collection, regardless of what filters are applied.

Selecting bars on the Timeline will highlight that time unit’s genomes on other panels.

Setting the date range filter

The date range can be set by typing the start and end dates, by using the calendar-based Date-Picker, or by dragging the filters in the Timeline Overview. You may want to change the displayed time Units to ensure the granularity matches your filtering parameters.

Once the date range has been set, the range window can be dragged back-and-forth to see the same size window over different timeframes.

Playback to see changes over time

The timeline can be played to show changes over time. “Speed” affects the speed at which the Unit bars are added to the histogram in Playback mode. This allows you to watch all the panels change over time.

Tip - If the endpoints on the Timeline Overview have been set, then the playback will continue from that endpoint onward. To begin midway through the timeline, select only the first unit of the region you wish to play. To begin at the beginning of the timeline, either select the first bar or the entire timeline.

Units

Adjust the “Unit” lozenge to change the width of the histogram bars (e.g. from “Year” to “Month”)

Units adjust the width of the bars in both the Filtered and Overview Timelines, as well as the way Playback happens.

Type: Bar or Normalised Bar

Adjust the “Type” lozenge if you prefer to view the relative proportion of colours using a Normalised Bar Chart.

• Bar Chart: shows the number of samples per date unit, stacking each colouring category.

• Normalised Bar Chart: shows the proportion of samples per colouring category, regardless of the total number of samples, per date unit.
