What type of data is best visualized with a heat map?
Because of their reliance on color to communicate values, Heat Maps are perhaps most commonly used to display a more generalized view of numeric values. This is especially true when dealing with large volumes of data, as colors are easier to distinguish and make sense of than raw numbers.
Is heatmap used for multivariate analysis?
A heatmap is a useful visualization method to illustrate multivariate data when there are many variables to compare, such as in a big data analysis. It is a plot that displays values in a color scale in a grid.
How do you compare two heatmaps?
A comparison of two heatmaps is essentially just a comparison of two histograms, or distributions. Thus an alternative to our visual approach is to use statistical tools that compute the difference between two distributions.
