Apprendre Choosing the Right Visual | Visualizations and Interactivity

Glissez pour afficher le menu

Before building any visual, it helps to know which one actually fits the question you're trying to answer. This chapter introduces a practical decision framework for choosing between the most common Power BI visual types: bar and column charts for comparison, line charts for trend, pie and treemap for composition, scatter plots for relationships, and cards for KPI summaries.

You'll learn what each visual type is optimized for, what to avoid (pie charts with too many slices, 3D charts, misleading dual axes), and how to navigate the Visualizations pane in Power BI Desktop. The goal is to make visual selection a deliberate choice rather than a default habit.

1. You want to show how `Total Sales` has changed month by month over the past year. Which visual type is most appropriate?

2. A pie chart works well for composition questions, but becomes hard to read when you have many categories. What is a better alternative for showing composition across eight or more categories?

Tout était clair ?
