Multiple Fields Color Theme Add-In (beta)

The Color Theme (Multiple Fields) add-in provides you with a new way to visualize and compare multiple fields of data. Also known as plurality maps, relationship maps, bivariate maps, or multivariate maps, multiple field themes can reveal patterns and let you see how items are connected. This is achieved using a method known as multivariate choropleth mapping, in which multiple color ramps merge to display all pattern combinations in a grid-like legend.

  1. Download the file color-theme-multiple-fields-addin.exe.
