drill down from one widget to another widget

There's the 'Widget affects dashboard filters' option, which allows you to filter the rest of the dashboard based on a click in a widget. (Or just drill down inside the widget, of course)

There also is the Accordion Plugin that opens a separate dashboard slide-out from an indicator widget, allowing more analysis.

Or the Jump to Dashboard plugin that will open a pop-up dashboard from a given widget, with optional filters from the row/segment/column/bar you clicked on.

In newer Sisense installations, Accordion and JTD are included by default and you don't have to install them separately but you may need to activate them.\

Good Luck!
