Qualitative, sequential, diverging
There are three types of color scale, each designed to highlight different things in a visualization.
Type | Purpose |
---|---|
qualitative | Distinguish unordered categories |
sequential | Show ordering |
diverging | Show above or below a midpoint |
Here you can see the results of a survey about math anxiety from a class of students. Each question has its own row, and responses range from "Strongly Disagree" to "Neutral" to "Strongly Agree".
Choose an appropriate color scale for the plot.
