Interactivity

A slicer for Month lets you pick January or February. Selecting a month updates all visuals to show data only for that month. This helps focus on one time period at a time.

A slicer for Region filters the bar chart, line chart, and table to show only the selected region's data, making it easier to compare regions.

Self Check

If you add a filter for Region = South, which components update?

• The Total Sales KPI card updates to show sales only for South (2800).
• The Sales by Region bar chart updates to show only South's sales bar.
• The Sales Trend by Month line chart updates to show South's sales trend.
• The Sales Details table shows only rows where Region is South.

Key Result

A clear sales dashboard showing total sales, sales by region, monthly trends, and detailed data with interactive filters for month and region.
