Page History

The sunburst chart is a multi-dimensional chart that enables you to visualize hierarchical data. The data is organized and displayed in a series of correlated rings where the innermost ring represents the top hierarchy. The outer rings are arranged and colored to indicate their hierarchical relationship with the inner rings.

In the sample data source, you will notice that Visualization has moved the Product Category Dimension to the Color Deck, moved Profit Measure to Rows Deck, and Order Date Dimension to the Label Deck. Also, the Product Category Dimension is moved to the Label Deck. The order of hierarchy formed in Sunburst is based on the placement of dimensions in the Label Deck. You can rearrange the fields in the Label Deck, to change the order of grouping in the chart. In the above example, Product Category forms the inner circle, followed by Order Date that forms the outer circle. Moreover, Visualization places the first dimension to the Color Deck for better display. When you change the default grouping, the chart visualization changes accordingly.

In the sample data source, we have changed the YEAR(OrderDate) to QUARTER(OrderDate) and moved it to the Color Deck so that you can analyze profits of each quarter based on the order date of the product categories.
