There are four powerful filters in Plannuh: Timeframe, Segment, Goal, Expense Status
When you select a filter, it persists across the Dashboard and the Plan Detail tabs.
The Timeframe filter allows you to zoom in on one or more of your timeframes (e.g. one or more months, one or more quarters)
The Segment filter allows you to view just the data for the selected Budget Segments.
The Goal filter lets you view by one or more Goals
The Expense Status filter lets you view your budget by Planned, Committed, and Closed Expenses
To clear the filters, you click the "Clear Filters" icon in the top menu bar. Here's an example of a drill down using all filters:
