What is a correlation heatmap?

A correlation heatmap uses colored cells, typically in a monochromatic scale, to show a 2D correlation matrix (table) between two discrete dimensions or event types. … Correlation heatmaps are ideal for comparing the measurement for each pair of dimension values.

What does correlation mean?

A correlation is a statistical measurement of the relationship between two variables. Possible correlations range from +1 to –1. … A correlation of +1 indicates a perfect positive correlation, meaning that both variables move in the same direction together.

How do you interpret a heatmap correlation?

Correlation ranges from -1 to +1. Values closer to zero means there is no linear trend between the two variables. The close to 1 the correlation is the more positively correlated they are; that is as one increases so does the other and the closer to 1 the stronger this relationship is.
