For example, weight and height would be on the y-axis, and height would be on the x-axis. If no dependent variable exists, either type of variable can be plotted on either axis and a scatter plot will illustrate only the degree of correlation (not causation) between two variables.Ī scatter plot can suggest various kinds of correlations between variables with a certain confidence interval. The measured or dependent variable is customarily plotted along the vertical axis. If a parameter exists that is systematically incremented and/or decremented by the other, it is called the control parameter or independent variable and is customarily plotted along the horizontal axis. Overview Ī scatter plot can be used either when one continuous variable is under the control of the experimenter and the other depends on it or when both continuous variables are independent. The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. If the points are coded (color/shape/size), one additional variable can be displayed. Ī scatter plot (also called a scatterplot, scatter graph, scatter chart, scattergram, or scatter diagram) is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. The different variables are combined to form coordinates in the phase space and they are displayed using glyphs and coloured using another scalar variable.
This scatter plot takes multiple scalar variables and uses them for different axes in phase space. A 3D scatter plot allows the visualization of multivariate data.
