When I need to change the layer that my indicator is viewing it removes all the setting that I have set ie filters, colors. How do I change my data and basically not have to redo all that work
You can use ArcgIS Online Assistant to do that. First, make a copy of the dashboard (in case it gets messed up). From the "I want to" dropdown, select "View an Item's JSON". Select your dashboard copy and in the Data portion of the code, click the Edit icon. In the widget you want to change, look for the "dataSource" property and change the "itemId" property. Click the Save icon and view the dashboard to see if it worked properly.
Please vote for the enhancement on the ArcGIS Ideas site, Operation dashboard - Add the ability to save as a template
Hope this helps,
