Cluster
The Cluster visualization method is useful for analyzing large numbers of points on the map. In this case, it is more convenient to work with clusters (groups of points). The size of a cluster depends on the number of points it contains.
When you zoom in the map, large clusters first split into smaller clusters, and then into separate points. When you zoom out the map, clusters are grouped into larger ones.
Overview
To select a visualization method:
- Go to the Dashboards tab.
- Open the required dashboard.
- Open a scene using the arrows
and 
. If there is only one scene in the dashboard, it opens automatically. - To open the layer, click
icon and select the required layer. - In the General settings block, select the Cluster visualization method.
- Set the remaining visualization parameters if necessary.
The data is visualized on the map.
Parameters
Tooltip setup
Parameter | Description |
|---|---|
| Tooltip setup | Enable the option to customize the list of attributes that are displayed in the tooltip when hovering over the cluster on the map. Select the required attributes, change their order, and select an attribute aggregation type if necessary: for more details, see the Configuring a tooltip section. If the option is disabled, the tooltip shows all attributes from the dataset. |
Radius
Parameter | Description |
|---|---|
| Cluster size | Size of the cluster in pixels from 1 to 250. A point is included in the cluster if it is located at the specified distance from its center. |
| Radius range | Radius of the cluster in pixels from 1 to 100. |
Color
Parameter | Description |
|---|---|
| Color basis | Numeric attribute that determines the fill color of clusters on the map and in the legend according to the color palette. Available values depend on the data in the sample. |
| Color aggregation type | Function used to aggregate the attribute values located in one cluster:
|
| Type of scale | Distribution type used to calculate data ranges in the legend:
|
| Number of ranges | Number of data ranges in the legend and colors in the palette from 1 to 10. Ranges are calculated automatically based on the Type of scale (for Logarithmic, Linear, and Exponential types). To customize ranges manually, enter the required limits or change the order and number of ranges (Adjustable type). In all ranges except the last one, the specified upper (right) limit is not included in the range.To change the order of ranges, hold down  icon next to the range and drag it. To add a range, click  icon. To delete a range, click  icon. |
| Palette | Color palette (a set of prepared color samples). To change the color for a range, click the color in the legend and select a new one from the palette or specify it in the HEX format. To reset the color, hover over it and click  icon. The color is also reset when the attribute is changed, but is not reset when the range limits or the number of ranges are changed. Example: |
| Invert | Enable the option to invert the color palette. All colors in the palette are inverted, except those set manually. |
| Opacity | Opacity of cluster fill in percent. |
Outline
Parameter | Description |
|---|---|
| Outline | Enable the option to display the cluster outline. |
| Outline color | Outline color. Select a color from the palette or specify it in the HEX format. |
| Stroke width | Stroke width in pixels from 1 to 25. |
