A sudden fall in the number of flights detected by my ADS-B tracker. The horizontal axis represents the time, each data point is a single day.
@ponygol I absolutely agree but those graphs originally were created just for me and there are many of them, all with the same X axis, hence no labels which were just creating visual noise as I knew what is on the graphs. Not very good for other people.
@boreq Axis labels, i.e. which day, would be good.
