Tableau’s robust calculation language makes it easy to augment your analysis with arbitrary calculations and perform complex data manipulations with concise expressions.
With calculated fields, you can easily perform arithmetic operations, express conditional logic, or perform specialized operations on specific data types. Two key capabilities that enable advanced analysis are Level of Detail (LOD) Expressions and Table Calculations.
An LOD Expression is used to calculate the running sum of total sales by first quarter of purchase date.
Since much of the world’s data can be modeled by time series, Tableau natively supports rich time-series analysis. You can explore seasonality, sample your data, or perform other common time-series operations within a robust user interface.
The visualization below shows the tipping patterns from all the taxi rides in New York City. You can easily adjust our sampling to find interesting patterns within the data. With a single click, you can disaggregate the data or view the entire time series sampled by an arbitrary window. You can quickly change aggregation frequencies to look for seasonality over different timescales or even view year-over-year (or quarter-over-quarter) sales growth.
