Part 4/9:
Filters in Tableau allow users to narrow down the data being analyzed. This capability is vital when focusing on specific datasets, such as filtering sales data by region or time frame. Tableau offers various types of filters:
Extract Filters: Define what data is included when connecting to data sources. This optimizes workbook performance, especially with large datasets.
Data Source Filters: Applied across the entire data source, ensuring that all sheets within the workbook use the same filtered data.
Context Filters: Create subsets of data that other filters will act upon, and are particularly useful in dependent filtering situations.
