Hi @Goldendelicious , Short answer: Unfortunately, there is currently no built-in way to display dynamically calculated statistics on a map. A statistics table can be created easily by using the Chart widget and its chart output data. If a filter is applied to the original layer, the chart output data updates automatically, so the statistics remain synchronized with the filter. However, there is currently no built-in way to display these dynamic statistics directly on a map. Even if such a layer were available, configuring its symbology based on dynamically generated statistics would be another challenge. One possible approach is to use a joined layer view to display aggregated statistics on the map. However, the joined layer is based on precomputed data and does not respond to filters applied to the original layer at runtime. Another option is to use a related table. With the help of message actions, both the original layer and the related table can be filtered simultaneously. However, it is not possible to configure the original layer's symbology from values in the related table. This limitation remains even when using Arcade, because the visualization profile does not support FeatureSetByRelationshipClass. As a result, the layer's symbology cannot reflect the dynamically updated statistics after the filter changes. Regards, Shengdi ... View more

Hi @Crinoid ， Inserting an Arcade expression into a text widget should work. The Arcade script should be something like the following: // Get the features currently selected on the map. var selectedFeatures = $dataSources["dataSource_id"].selectedFeatures; // Exit if no features are selected. if (Count(selectedFeatures) == 0) { return "No features selected."; } // Retrieve the first selected feature. // (This script assumes only one feature is processed.) var selectedPt = First(selectedFeatures); // Get the level for the selected feature. var level = selectedPt.PRestictionLevel; // Return the corresponding level description. if (level == "Level 1") { return "Level 1 is ....."; } else if (level == "Level 2") { return "Level 2 is ......"; } else { return "Level 3 is ......"; }   Please let me know if you have other questions.
