# Adding filters to an Analyzer report In Pentaho Analyzer, filters are used to restrict or limit data in a report, so you can build the report to show only the information that you want to view. For example, a typical report shows sales by product line. By applying a date filter on Quarter, you can restrict the data so that only sales for the one quarter are shown. If you add a string filter for Europe, the report would display data for the European sales that quarter. If you add a string filter on another field to exclude a product line, the report would display European sales data in that quarter minus the excluded product. You can apply a filter by selecting it from a list, or you can choose a specific type of filter to refine the data the way you want: * [Date range](/pba/pentaho-analyzer-cp/adding-filters-to-an-analyzer-report/create-date-range-filters.md) * [Comparison on numeric levels](/pba/pentaho-analyzer-cp/adding-filters-to-an-analyzer-report/create-a-comparison-filter-on-a-numeric-level.md) * [String on a level](/pba/pentaho-analyzer-cp/adding-filters-to-an-analyzer-report/create-a-string-filter-on-a-level.md) * [Measure values](/pba/pentaho-analyzer-cp/adding-filters-to-an-analyzer-report/create-a-filter-on-measure-values.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
