Citywide scorecard data for the Seattle city energy app is pulled from a dataset in the cityenergy-seattle carto account. The carto dataset name must be set in the configuration (seattle.json) file.
Locate the "scorecard" block in the seattle.json file mentioned above. Within this block, find the citywide sub-block. Set the table field with name of the dataset containing citywide data in Carto.
All data will be pulled from the Carto dataset that is set for the citywide.table field in the configuration file. New data will be automatically picked up the next time the web app is reloaded.
It's important to remember that any changes made to the seattle.json file will need to be "re-deployed" to be active in the production version. See the documentation in the main README file for how to deploy to production.
