Time series analysis in Tableau involves analyzing data points collected or recorded at specific time intervals. It helps to identify trends, seasonality, and patterns over time, making it a critical tool for understanding how data evolves. Tableau offers robust capabilities for time series analysis by allowing users to plot time-related data in a way that highlights underlying trends and cyclical patterns.
In Tableau, time series charts are commonly used to analyze metrics like sales, website traffic, stock prices, and other key performance indicators (KPIs) that fluctuate over time. By leveraging Tableau’s built-in date hierarchies and advanced visualizations, users can drill down into yearly, quarterly, monthly, or even daily data to uncover meaningful insights.
