This is because vastly more testing was conducted after mid-May, and a higher percentage of infections were caught. The red curve still follows it, but the ratios are completely different. But after about mid-May, the blue curve shoots up. If you look at the left third of the chart, you can see the red curve follows the blue curve, lagging slightly behind. This chart also makes it easy to see that the relationship between positive tests and deaths is not what it once was. If you look at the blue lines around Labor Day, you can see a conspicuous dip followed by a spike.
Sometimes there are exceptions, such as severe underreporting around holiday weekends.
You can see that in the “hills and valleys” of this graph. We typically see a weekly reporting pattern of underreporting on Sunday and Monday and overreporting on Tuesday and Wednesday. The main thing I look for in this graph is unexpected noise in the data. The axis is scaled so that the positive test scale is 10 times the deaths scale. The blue lines represent positive tests, and the red lines represent deaths. The most foundational graph is the one that shows the raw data on daily positive tests and deaths, as shown below. I include the charts that I personally find useful in understanding the status and trends of the pandemic.
