Layer Management

Once you've added catalog layers, the Layer List view in the catalog dialog lets you manage them. This page covers everything you can do from the layer list.

Layer List View

The layer list shows all configured catalog layers and any non-catalog layers, sorted by z-index (stacking order). Each row displays:

• Layer name
• Z-index value
• Edit button — reopen the configuration panel for this layer
• Remove button — delete the layer

The Background Map row always appears at the bottom and cannot be reordered.

Reordering Layers

Layers are rendered in z-index order — higher values render on top of lower values. You can reorder layers in two ways:

1. Drag and drop — click and drag a layer row to a new position in the list. The z-index values update automatically.
2. Edit z-index — click the z-index value and type a new number directly.

This is important when you have overlapping layers — for example, placing a transport network layer above a boundary layer so that lines are visible over filled polygons.

Editing a Layer

Click the Edit button on a layer row to reopen its configuration panel. You can change any setting — fill, outline, labels, data binding, filters, and so on. Click Save to update the layer's configuration.

Removing a Layer

Click the Remove button on a layer row to delete it. The layer is removed from the list immediately. This action takes effect when you click Apply Changes.

Layer Limits

You can add up to 10 catalog layers per visual. The "Add New Layer from Catalog" button is disabled when this limit is reached.

Applying Changes

Click Apply Changes at the bottom of the layer list to close the dialog and save all changes. Each layer's configuration is persisted as a JSON string in the Power BI visual's settings, so it travels with your PBIX file.

Changes only take effect when you click Apply — if you close the dialog without applying, no changes are saved.
