How do I choose the right chart?

Start with the analytical question: comparison, trend, distribution, relationship, composition, geography, flow, uncertainty or exact lookup.

When should I use a bar chart?

Use bars to compare magnitudes across discrete categories, usually with a zero baseline and meaningful sorting.

Use a line chart for change across ordered, sufficiently continuous time points, with missing periods and forecasts clearly identified.

Use a table for exact lookup, many values, mixed measures or an accessible representation that a visual cannot supply alone.

They can work for a few clearly different shares, but bars are usually better for precise comparison or many categories.

Use clearly labelled intervals, ranges, distributions or scenarios and distinguish forecasts from observed values.

Ask representative users to find values and state conclusions, then measure accuracy, time and accessibility in the real context.
