Timeline Chart

The Timeline chart shows you the development of your search field and your selection over time. Use it to understand whether a topic is on the rise or decline.

Use the timeline visualization to see the development of your search field over time. It uses the publication date of the Signal on the time axis.

Note the extended options that can be opened by clicking on the three dots (...) in the top-right corner.

Selecting a Timeframe

See a spike or dip in the timeline? Simply drag and drop your mouse cursor across that part of the visualization to select the timeframe. The visualizations and bar charts, as well as the list of Signals will be filtered down accordingly.

You can also pick the time frame more precisely using the date range picker in the extended options (see 1 above). This is also the place to remove the selection, by click on the "x" in the date range picker.

Grouping and Comparing

You can select a property to group Signals by from the extended options (see 2 above). This allows you to compare the development of those groups over time. Currently, you can select the Signal type (which is selected by default) and the country properties for grouping.

If the filter contains many values, only the top 5 values will be displayed as a separate series. If you want to choose which values to compare, just filter for those using the respective filter in the Filter tab (Or try using the world map visualization for selecting countries).

Normalizing the Series

By ticking the "Compare Growth" checkbox in the extended options (see 3 above), you can normalize each series by its maximum value during the period defined in the search field.

Why would you want that? Sometimes, the absolute numbers across the groups can differ substantially, making it hard to compare the development of the series. It can be hard to see which of the series shown is growing stronger or declining faster. Normalizing solves this issue by adjusting the scale and making it easier to compare the series.
