About Ask Data
Ask Data lets you type a question in the same language and instantly get a response in Tableau. In Ask Data, answers come in the form of automatic data visualizations, with no need to manually drag-and-drop fields. Ask Data lets you ask Logical questions naturally, with support for analytical concepts like time series and spatial analysis, and an understanding of conversational phrases like Last year.
Before Starting the Process, we have to be very sure that our Data-source and workbook are published on the Tableau Server to perform the Visualization.
