You can apply different data labels to each point in a scatter plot by the use of the TEXT command. You can use the scatter plot data as input to the TEXT command with some additional displacement so that the text does not overlay the data points. A cell array should contain all the data labels as strings in cells corresponding to the data points. Online Tool to Calculate Linear Regression and Graph Scatter Plot and Line of Best Fit. Simple linear regression is a way to describe a relationship between two variables through an equation of a straight line, called line of best fit, that most closely models this relationship.

Dec 26, 2015 · Simple linear regression is an effort to explain the dynamics within the scatter plot by developing a formula for a straight line that best fits the data. This has nothing to do with a theoretical framework. A scatter plot precedes development of a regression formula. Scatter Plot (also called scatter diagram) is used to investigate the possible relationship between two variables that both relate to the same event. A straight line of best fit (using the least squares method) is often included.
