One way to add a layer to a map chart is to duplicate an existing
layer. You can duplicate layers from any map chart in the analysis, and using
any client.
Procedure
-
In the Visualization properties panel, select the layer of
interest, and, from the context menu, select
Duplicate layer.

You can
also duplicate layers from the visualization properties popover or dialog. In
the web client, click to select the layer of interest in the visualization
properties popover and click
Duplicate layer. In the installed client, you
can open the visualization properties dialog, go to the Layers page and click
to select the layer of interest, and then click
Duplicate. If there are more map charts in the
analysis you can also select to duplicate a
Layer from another map chart here.
The duplicated layer is added to the map chart.
-
Optionally,
move the new layer to a new position and
update its properties.
