Interactivity

Add a filter for Month. When you select a month, the Monthly Sales Table and Column Chart update to show only that month's data. The Bar Chart updates to show sales by category for the selected month only.

Self Check

If you add a filter to show only February, which components update and what do they show?

• Monthly Sales Table: Shows total sales for February (1500 + 700 = 2200).
• Column Chart: Shows a single bar for February with height 2200.
• Bar Chart: Shows sales by category for February: Electronics 1500, Clothing 700.

Key Result

Dashboard shows monthly total sales as a column chart and product category sales as a bar chart with interactive month filtering.

Practice

1. What is the main difference between a column chart and a bar chart in Google Sheets?

easy

A. Column charts display vertical bars, bar charts display horizontal bars.

B. Column charts show percentages, bar charts show totals.

C. Column charts can only show one data series, bar charts can show multiple.

D. Column charts are for dates, bar charts are for text labels.

Solution

1. Step 1: Understand chart orientation

   Column charts use vertical bars to represent data values, making it easy to compare heights.

2. Step 2: Understand bar chart orientation

   Bar charts use horizontal bars, which are useful when category names are long or many.

3. Final Answer:

   Column charts display vertical bars, bar charts display horizontal bars. -> Option A

4. Quick Check:

   Orientation difference = vertical vs horizontal [OK]

Hint: Remember: columns go up/down, bars go left/right [OK]

Common Mistakes:

• Confusing orientation of bars
• Thinking column charts show percentages only
• Assuming bar charts can't show multiple series
