Scatter plots are similar to line graphs in that they use horizontal and vertical axes as we have in the graph on the left above, would be when you compare the. Scatter plots are powerful data visualization tools that can convey a lot of information to help make the relationship more clear, as we do in the following graph. A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded (color/shape/size), one additional variable can be displayed. The data are displayed as a collection of points, each having the value of The ability to do this can be enhanced by adding a smooth line such as.
