Chart Selection

Matching the chart to the task: bar to compare, line for trends, histogram or box plot for distributions, scatter for relationships.

Definition

Position and length are the most accurately perceived encodings, so bar and line charts are usually more readable than pie, gauge or 3-D charts. Maps suit only data with a meaningful geographic component.

Exam tip

Trend over time = line; comparing categories = bar; correlation = scatter; distribution = histogram.
