Point layers
A point layer overlays individual locations on a map, representing them with shapes.
By default, point layers use circular bubbles, but you can also use several other shapes. You can also use custom images as the points in a point layer. The size of the points in your layer can be fixed or you can specify a measure or expression to set the sizes of the different points. You can highlight these differences in values further by coloring by measure.

Adding a point layer
Do the following:
- From Layers in the advanced properties, click Add layer and select Point layer.
- In Dimensions, click Add and select a field containing point data to use as the dimension.
-
If there are issues with the point locations, adjust the location settings in Locations in the properties panel.
For more information, see Map chart.
-
Optionally, in Options > General, after Max visible objects, set the maximum locations to display in the layer.
The maximum number of values in a map layer is 50,000. By default, layers display a maximum of 4,000 values for point layers and 1,000 for other layers.
Once the layer is added, you can adjust settings for the layer in the properties panel.
