Is it possible to use a geoprocessing map server result in a widget in Web App Builder? I have a geoprocessing service that is set to return a map service, I want to be able to use the chart widget to graph the resulting data. However, whenever I add the GP services's map server URL the chart widget only plots the data the tool output when it was published, or it returns an error. I'm at a loss as to what is going wrong, any help is appreciated.
