Central vertigo and dizziness are symptoms of a disorder or disease that is affecting the brain or brain stem. Both vertigo and dizziness can affect your sense of motion and balance and ability to perform some activities such as driving.
A scatter plot, scatterplot, or scattergraph is a type of mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.If the points are color-coded you can increase the number of displayed variables to three.or a set of data variables (dimensions) X 1, X 2, ... , X k, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format. For k variables, the scatterplot matrix will contain k rows and k columns.
The first technique is the scatter plot analysis, first described by Touchette, MacDonald and Langer (1985). Once you've built your square to contain all the information you need, you can export the square to Google Spreadsheets and create a rough scatter plot.
