Correlation Matrix


A correlation matrix is a certain map type that is able plot correlations between certain sets of data. In this example, the matrix is showing the relationship between T7 proteins. As you can see from the scale located on the right side of the diagram, red suggests a strong correlation while the blue shows a weaker correlation. To locate the correlation between the two variables, you need to find the value in the table for the row and column intersection for those two variables.
