What does the left figure show? | The expected number of new cases over time, if tomorrow's numbers are normal/good/bad. |
---|---|
... and the right figure? | The "flattening" of the curve over time. Large negative numbers mean more flattening. The red area is the danger zone. |
Why do some plots say "uncertain results"? Why are some states or countries missing? | These cases do not have a long enough history, or have too many outliers, or their results are too sensitive to recent numbers. This typically happens when "flattening" in the right plot is nearly zero or positive. |
