Widgets
In Builder, widgets empower users to dynamically explore data, leading to rich visualizations. They also serve to filter data based on the map viewport and interconnected widgets.
Below are the current type of Widgets available to customize your visualization and enable a richer interaction with your data:
Formula Widget: Shows aggregated numerical data as a single metric.
Category Widget: Segments data into distinct categories displaying aggregated metrics.
Pie Widget: Visualizes categorical data by displaying the proportion of each category relative to the whole data set.
Histogram Widget: Shows the frequency distribution across equal bins in the data range.
Range Widget: Shows a specific range of numerical data adjustable via slider or input values.
Time Series Widget: Shows the frequency distribution aggregated by a temporal period. It also allows to create animated maps.
Table Widget: It shows tabular information of the features in the viewport.
Adding a Widget
Add a widget to Builder by clicking "New Widget" and select your data source.
Then, select a widget type from the menu: Formula, Category, Histogram, Range, Time Series or Table.
Configuring a Widget
Once you have selected the widget type of your preference, you are ready to configure your Widget.
Widget Data
In the Data section of the Widget configuration, choose an aggregation operation COUNT, AVG, MAX, MIN or SUM and, if relevant, specify the column on which to perform the aggregation.
When working with aggregated data sources, you will need to select an aggregation operation for your columns.
Connections to Redshift clusters don’t support aggregation of categorical properties.
When working with pre-generated tilesets, please ensure your data have a unique identifier named geoid for correct Widgets calculations.
Widget Display
Using the Formatting option, you can auto-format data, ensuring enhanced clarity. For instance, you can apply automatic rounding, comma-separations, or percentage displays.
You can use Notes to supplement your Widgets with descriptive annotations which support Markdown syntax, allowing to add text formatting, ordered lists, links, etc.
Widget Behavior
Widgets offer two distinct modes of operation: "Viewport" and "Global."
Viewport Mode
By default the widgets work in viewport mode, meaning the data gets updated when the viewport extent changes. For simple features, viewport widgets get the data by performing a SQL query to the data warehouse; whereas, if you are working with aggregated grids or pre-generated tilesets, viewport widgets work with the data that has been downloaded for visualization which is available locally in the browser.
Global Mode
You can configure Widgets to make use of the global mode where information is displayed for the full data source. This option does not take into account the viewport extent of the data. Note that global mode is only available for simple features and the data is retrieved by performing a SQL query to the data warehouse.
Please be aware that global mode is not supported for Spatial Indexes or pre-generated tileset sources. In such scenarios, the functionality defaults to viewport mode. This means that all calculations are based on the extent of the map's current viewport.
In the Behavior section of Builder, you have the option to make Widgets collapsible, allowing them to be hidden when needed. Additionally, widgets can be set to automatically collapse when their associated layers are not visible. Moreover, certain widgets possess the ability to concurrently filter themselves, their related widgets, and layers connected to the same data source. This filtering functionality can be conveniently enabled or disabled for individual widgets using the cross-filtering toggle icon.
As Widget settings differ between widget types, please visit the individual widget's documentation page for more detailed information.
