These log graphs provide a different perspective on the rate of Covid-19 positive tests and deaths. On most graphs, the x-axis is time. On these graphs, the x-axis is the total number of cases to date, and the y-axis is the number of cases added incrementally each week. As the pandemic winds down, the graphs will show a sharp downward direction on the right, due to the decline in the number of incremental number of cases being added each week.
These log graphs make it very easy to see if the state is “flattening the curve.”
For most states the shape will be mostly smooth. For states with small populations, small numbers of tests/deaths, or both, the shapes can be irregular.
