Change the Dimensions of the Test
Another useful way to make patterns jump out at you is to change the dimensions of the data. For example, if you simply change the scale of the test you can take something that looks like Figure 3, a solid red line of transactions, and break it out into something like Figure 4, a chart in which you can see clear banding patterns and the time between transactions. That simple change was made by switching to a log scale.
Figure 3 Sample scatter chart on normal scale.
Figure 4 Same scatter chart on log scale.
You can also do things like change the scale values, change the units for each scale (minutes or milliseconds instead of seconds), or even invert the axes for a much different look at the data. Each of these approaches offers you a different view and allows you to zoom in and out on the data in different ways.
