Using Layer Analysis Nodes with Widgets

Learn how to assign layer nodes to Builder widgets.

If you have a chain of analysis - that is one or more analysis attached to a layer - you should bear in mind the following behaviors:

On the one hand, if your widget is pointing to a layer node at the bottom of the analysis, the data will be filtered and the analysis on top will run again only with the selected data.
On the other hand, if your widget is pointing to a layer node at the top of the analysis, the data will be filtered with the output of the analysis.

In addition, if you want two different layers to be filtered at the same time, there are a couple of options:

If the layer is a duplicate (it comes from the same data source), you can drag the layer node out instead of adding the layer several times to Builder as explained in this GIS SE answer.
If the layers have different data sources, you can use Builder Link second layer analysis.
