Power BI lesson 2
Visuals answer different questions. Tables show detail, cards highlight one number, charts compare or show change, and slicers let a reader filter.
Build a first report
- Load the SalesPractice table from lesson 1.
- Add a Table visual and place Product, Region and Amount into it.
- Add a Card and use Sum of Amount for a headline total.
- Add a clustered column chart with Product as the category and Sum of Amount as the value.
- Add a slicer using Region.
Choose the right visual
Use a line chart for values over time, a bar chart for category comparison, a card for one KPI, and a table when exact rows matter. Avoid decorative charts that do not answer a question.
How filtering works
Selecting East in the Region slicer changes the other visuals to show only East rows. A visual can also cross-filter another visual when you click a bar or point.
Formatting checklist
- Give every visual a meaningful title.
- Use readable number formats such as currency.
- Keep similar colors for the same meaning.
- Leave enough space and remove unnecessary borders.
Practice
Add a second slicer for Product. Change the chart to a line chart using Date. Write one sentence describing the decision your report helps with.
