MediaContent | API Reference | ArcGIS Maps SDK for JavaScript 4.31

A MediaContent popup element contains an individual or array of chart and/or image media elements to display within a popup's content.

Chart colors automatically respect renderer colors when visualizing data with the predominance, dot density, and pie chart renderers. Binning and clustering popup charts are also based on the renderer colors. However, popup charts only respect the colors from the pie chart renderer when clustering is configured.
