When analyses are applied to map layers (A, B, C, D), the results are included as a node (A1, A2, B1, B2) within your data. Analysis nodes act like sublayers in association with each map layer that they are applied to. Sublayers can then be selected as the source for creating widgets, initiating dynamic filtering. Any time the widget is filtered, the analysis is run and recalculated based on the selected filters.
This guide describes how analysis results run, and rerun, when filtering and exploring data with widgets.
From the LAYERS pane in Builder, a map layer indicates when analyses are applied as part of the workflow for rendering data.
For example, the following image displays the Join Columns from 2nd Layer analysis
A1, applied to the Election 2016 layer
You can chain several different analysis nodes to a single map layer, or automatically create a new layer from analysis results.
When creating widgets, you can select the analysis node as the layer of data to be used for the widget.
From an open map in the Builder, select WIDGETS.
The WIDGETS pane appears, where you can add and manage widgets. The following example indicates that all of the existing widgets are filtering by the analyzed results
Click ADD to add a widget.
Select the type of widget to be added (CATEGORY, HISTOGRAM, FORMULA, TIME-SERIES).
Select the checkbox next to the column(s) to be included for the widget.
Select the layer to be used for the widget.
The following example displays the
A1 analysis node being selected as the source of data for a category widget.
The selected widget(s) appear on your map visualization, and the WIDGETS pane displays the Type, Data, and Behavior options for the widget.
The widget enables you to filter and explore the selected analyzed data.
