I am looking to create an app similar to this water quality data viewer developed by a local watershed organization. The goal is to display a time series of historic data (in a related table) by site and to include thresholds (ideally in the chart) and a discussion of each parameter. I understand that the data viewer charts widget the above site was developed on is no longer available. Is there a replacement or does anyone have a recommendation for a tool I could use instead? [This is for a non-profit, so I'm limited to an AGOL creator license]
