I have been trying to use the Web AppBuilder (WAB) "Infographic" widget (pie chart) in conjunction with the Time Slider. The web map display is working properly, but the Infographic pie chart does not update to reflect the time slider range. Am I doing something wrong, or is this not supported? Similarly, the "Attribute Table" widget does not reflect the settings of Time Slider.
Both the "Infographic" and "Attribute Table" widgets do work in conjunction with the "Filter" widget. They update as you set filters for the feature service.
I have tried this with an ArcGIS Online hosted feature service (with time enabled in the web map) and also with an older version of ArcGIS Enterprise feature service (10.3.1) where the time is enabled in the MXD. Perhaps it is supported on a higher version of Enterprise?
If this is not possible, I will need to log this as an Idea.
