When you select a field in a service-backed layer, the statistics and histogram Smart Mapping provides you are queried directly from the server. However, when you author an Arcade expression, the Map Viewer must calculate statistics from the expression directly in the browser since feature services don\u2019t support Arcade. <\/p>\n

Calculating these statistics used to be burdensome because they previously executed on the browser\u2019s main thread. That is what caused the freezing observed in the recordings at the top of this post. In December, the logic for calculating statistics moved from the main thread to worker threads. This prevents UI freezing and returns the results faster. <\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1435082,"id":1435082,"title":"grocery-store-line","filename":"checkoutimage_0.png","filesize":297867,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/a-better-experience-for-styling-layers-using-arcade-in-arcgis-online\/checkoutimage_0","alt":"An illustration of long lines of people checking out food at a grocery store.","author":"6561","description":"","caption":"Credit: AdrianHillman\/iStock\/Getty Images Plus","name":"checkoutimage_0","status":"inherit","uploaded_to":1434542,"date":"2021-12-10 20:20:41","modified":"2021-12-10 21:19:37","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":770,"height":400,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","medium-width":464,"medium-height":241,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","medium_large-width":768,"medium_large-height":399,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","large-width":770,"large-height":400,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","1536x1536-width":770,"1536x1536-height":400,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","2048x2048-width":770,"2048x2048-height":400,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","card_image-width":770,"card_image-height":400,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2021\/12\/checkoutimage_0.png","wide_image-width":770,"wide_image-height":400}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

You can think of this as standing in line to buy food at a grocery store register. Imagine having a cart full of food and discovering that only one register is open with a line of other shoppers backing up to the end of the store. Compare that experience with having 10 open registers with quickly moving lines. This allows you to choose the shortest line so you can make your purchase and leave the store faster. <\/p>\n

In a similar fashion, the statistic calculations previously had to wait in a queue of other tasks to finish their calculations. Now they have moved to smaller queues (i.e. workers), which means they can be resolved more quickly without blocking other logic in the app. <\/p>\n

Creating a good experience for non-ArcGIS data sources<\/h2>\n

The logic for calculating statistics for Arcade expressions is the same code path as calculating statistics for any data source not backed by an ArcGIS feature service or map service. Since data sources, such as GeoJSON and CSV, exist as text files, the browser needs to bear the burden of calculating statistics for data from those layer types.<\/p>\n

The performance improvements described above helped create a good experience for styling data in CSV and GeoJSON layers, which can now be added to ArcGIS Online maps by URL<\/strong> starting at the December 2022 update.<\/p>\n
