Tableau offers a good range of filters that we can apply on the data for better analysis.
Filters allow us to view our data at different levels of granularity and detail.
We can exclude unnecessary data through filters and conduct our analysis on only the required data.
There are five different types of filters available in Tableau.
1. Extract filters: These filters create an extract or subset of data from the original data source.
In other words, the extract filters extract a portion of data from the whole from its source. We can use the data extract anywhere in the analysis once it is created.
2. Data Source filters: The data source filters are the filter conditions that we can directly apply at the data source level.
Using the data source filters we can apply filters on the data present in the data source itself instead of first importing it into Tableau.
3. Context filters: The context filters are used to apply a context for the data that we are working on.
Once we apply a context filter on a worksheet or workbook, the entire analysis is done in that applied context only.
4. Dimension filters: Dimension filters are applied specifically on individual dimensions present in the Dimensions section on a Tableau sheet.
We can easily apply dimension filters on the dimension fields by dragging and dropping the field into the Filter card present on the sheet.
5. Measure filters: Such filters are applied on individual measure fields present in the Measures section on a Tableau sheet.
We can easily apply the measure filters on the measure fields by dragging and dropping the field into the Filter card present on the sheet.
