Farbcodierung des Hintergrunds des Listenelements mit Arcade-Ausdrücken in ArcGIS Dashboards

Zusammenfassung

Arcade expressions can be used in ArcGIS Dashboards to customize how the data points appear in the list, indicator, and table elements. A data point can represent a feature or a summary statistic, depending on how the element is set up. A single data point represents a single feature when using features, and each data point represents the result of a statistic when it is used.

This article provides the steps to color code the background of the List element in ArcGIS Dashboards. In this example, the field values in the Project Status field are referenced to determine the background color for each field value in the Route Name field.

Vorgehensweise

1. Open the ArcGIS Dashboards item. Click Layout on the dashboard toolbar, then the Options button next to the element. Click Configure.

2. Click List to open the List options menu, and click Enable.

3. Specify the following Arcade expression in the Expression window.

// Edit the desired color accordingly
var <variableName> = Decode($datapoint["<variable>"],
'<Field value 1>', 'red',
'<Field value 2>', 'orange',
'<Field value 3>', 'yellow',
'<Field value 4>', 'green',
'')

return {
  backgroundColor: <variableName>
}

4. Click Done.
