# Report Drill Downs

Drill downs enable you to get a different perspective from the same visualisation. 

For example, in the Pharma Market Insights report, when looking at the data visualisation of the prescribing items by period, you can use the drill/up controls towards the top of the graph to change the summary level from months...

...to quarters.

The controls for drilling down can differ depending on the visualisation. For example, in the Pharma Market Insights report, you can drill down from BNF chemical substance to BNF description using the +/- buttons.
