A map chart positions your data in a context, often geographical,
using different layers. The layers can be either data layers, such as marker
layers or feature layers, or reference layers, such as map layers, Tile Map
Service layers (TMS), Web Map Service layers (WMS), or image layers. By adding
different layers to the map chart, you can configure the map to suit your
needs. Each layer also contains a number of properties specific to the layer.
You can configure the properties for the map chart itself as well as for all
layers.
Before you begin
See
Map chart for a
description of the concept.
Procedure
-
On the authoring bar, click
Visualization types
to open the flyout.
-
Drag the
Map chart visualization type to the wanted
position on the analysis page.
A suggestion of a map chart is presented.
-
Follow the steps in
Adding layers to add more layers to your map
chart.
Tip: You can reuse the settings of an already existing
layer instead of adding a completely new layer. See
Duplicating a layer for detailed
instructions.
-
Click the label
Map chart at the top of the layer list to
review and configure the generic map chart properties. Here you can for example
change the
coordinate reference system or how to
navigate the map chart.
Tip: To better spread values on top of a background
image, you can specify the ratio of data values on the imaginary X- and Y-axes
in the map chart properties under
Appearance and
Ratio settings. By changing the ratio you
can stretch the data range so that markers are evenly distributed over an area
even if the actual values on the axes are of different dimensions. For example,
if your X-values range from 0 to 10 and your Y-values range from 0 to 100, you
can set the Y ratio to 10:1 for an even distribution of values.

Click on the different layers in the layer list to review or
configure layer specific properties.
