This functionality allows users to manipulate and transform data dynamically, facilitating the analysis and visualization of information. Field calculations can be simple, such as adding or subtracting values, or complex, involving logical, date, and text functions. By using field calculations, analysts can customize their visualizations and gain deeper insights, tailoring the data to their specific needs. This tool is essential for creating interactive dashboards and reports that require detailed analysis. Additionally, field calculations can be used at different levels, from row-level calculations to aggregated calculations, providing great flexibility in data handling. In summary, field calculation is a powerful feature that enables users to transform and enrich their data for better decision-making.
