Below the map charts are displayed after selecting a county or multiple counties on the map. The Main chart shows the 4 metrics from the last county you clicked on. The four Compare chart options compare each of the metrics for the last two counties the user clicked on.
Two counties must have been selected at one time for the compare charts to appear. Click on Main or any one of the Compare buttons to view that chart.
If the user wishes to compare a specific county to multiple counties (without needing to reselect it each time), they may use the Lock button that appears in the bottom left of the map after selecting the county of interest. This locks in their last selection and it will not be removed until they click the Clear button.
