To view this report, choose Correlation Chart from the report selector (at the top of the report pane) in the main window.

A correlation chart (scattergram) is used to plot the correlation between any two column values over a set of animal records. Typically you would use this to chart the relationship between two metrics over a large number of tagged records, or perhaps over all records listed in the main record table.

You select which two columns from the main record table are to be plotted. One is plotted against the X axis, the other the Y axis. A dot is placed at the appropriate position on the chart for every source animal record that has values present in both columns.

In addition the program will compute the Product Moment Correlation Coefficient (r) and Spearman Rank Correlation Coefficient (rs) for the charted data. These are displayed above the chart.

A typical use of this feature would be to plot a correlation of, say, the inbreeding coefficient against a sample metric such as weight or height.
