[**Secondary visualisations on Datasets number widgets**](/content/updates/20/index.html)

The Number visualisation in Datasets now supports showing a secondary visualisation.

You can show a fixed comparison to the previous value in the series, which is great for focussing on period-over-period improvement. Alternatively, a sparkline allows you to visualise how a metric is trending over time.
