Scatter plots are often used to find out if there's a relationship between variable X and Y. On to the how-to. One of the most common types of graphs you will want to make is a scatter plot. One variable is designated as the Y variable and one as the X variable, and a point is placed on the graph for each observation at the location corresponding to its values of those variables. Or, you can save it in a variety of formats. the chosen independent variable, a partial regression plot, and a CCPR plot. This is a good thing, because, one of the underlying assumptions in linear regression is that the relationship between the response and predictor variables is linear and additive.

A simple line plot for the data I have just displayed will go like this: twoway line unempl year. In most cases, Stata will use the numerical values (representing the different categories) of a variable to label the axes of a graph. If the categories have been labeled, Stata will use those labels only if a variable is used to represent different groups, such as when a box plot is created together with the over option. Purpose: Check pairwise relationships between variables Given a set of variables X 1, X 2, , X k, the scatter plot matrix contains all the pairwise scatter plots of the variables on a single page in a matrix format.
