T-$\nu$ Plot

As an example of a second type of T-plots, the T-$\nu$ plot will be introduced here. One of the variables of interest in analyzing movement patterns is the speed an object is moving. This aspect can be easily converted into a time plot where the horizontal axis represents time and the vertical axis speed. Such a plot is illustrated in figure 5.6. One advantage of this kind of plot often found in biological data is remarkable: outliers are conspicuous, often identified as errors in the data. This T-$\nu$ plot has been used before, but it is nevertheless presented here as a representative of an own kind of T-plots.
