Coronavirus: How to Do Testing and Contact Tracing - Tomas Pueyo - Medium
In this graph, daily new cases are the red line and daily new tests are the green line. They have been scaled, so that they can be compared. As we just saw above, the experience of countries that controlled the epidemic indicates we should aim for at least 3% of positives, which means you want ~33 times more tests than cases. So the tests axis on the right is ~33x bigger than the cases axis on the left. With that you can easily see when you have enough tests.
