Know the data

TIBCO Spotfire has many ways to help you get to know your data.

The Data in analysis flyout is automatically opened when you add a new data table. It shows you a structured list of all columns in the data table, where different types of columns are grouped into categories like NUMBERS, TIME, and so on. Numeric data is often used as summarized data on axes in a visualization, whereas categories are used to split the data in different groups. It is possible to change the categorization if the automatic attempt is not good enough. The behavior of a column when added to a visualization differs depending on how it is categorized.

To know the details of a data column, you can select it in the flyout, and click Details on selected column as shown below. You also get access to some data preparation and cleansing tools, which can help getting visualizations the way you want them. For more information, see Data in analysis.
