Vertigo could be either from a peripheral (labyrinth and vestibular nerve) or a central disorder (central nervous system). Central vertigo is usually a result of an abnormal processing of the vestibular sensory input by the central nervous system. See the image below.
scatterhist(x,y) creates a 2-D scatter plot of the data in vectors x and y, and displays the marginal distributions of x and y as univariate histograms on the horizontal and vertical axes of the scatter plot, respectively. example.
Example 8.41: Scatterplot with marginal histograms. The scatterplot is one of the most ubiquitous, and useful graphics. Itâs also very basic. One of its shortcomings is that it can hide important aspects of the marginal distributions of the two variables. To address this weakness, you can add a histogram of each margin to the plot.
