Practice

1. What is the main purpose of a Combo Chart in Excel?

easy

A. To display data in a pie chart format

B. To combine two or more different chart types in one chart

C. To create a chart with only one data series

D. To sort data automatically in a table

Solution

1. Step 1: Understand what a combo chart is

   A combo chart combines different chart types like column and line in one chart to show related data.

   Since combo charts mix chart types to compare data sets, To combine two or more different chart types in one chart matches this purpose.

3. Final Answer:

   To combine two or more different chart types in one chart -> Option B

4. Quick Check:

   Combo chart = mix chart types [OK]

Hint: Combo charts mix chart types to compare data sets [OK]

Common Mistakes:

• Thinking combo charts only show one data series
• Confusing combo charts with pie charts
• Assuming combo charts sort data automatically

2. Which Excel menu path correctly leads you to create a combo chart?

easy

A. Data > Sort & Filter

B. Formulas > Insert Function

C. Insert > Combo Chart

D. Review > Protect Sheet

Solution

1. Step 1: Recall where combo charts are created

   Combo charts are created from the Insert tab in Excel, under the Combo Chart option.

2. Step 2: Match the correct menu path

   Insert > Combo Chart shows the correct path: Insert > Combo Chart.

3. Final Answer:

   Insert > Combo Chart -> Option C

3. Given sales data for two products over 3 months, which combo chart type best shows Product A as columns and Product B as a line?

medium

A. Column for Product A and Line for Product B

B. Pie chart for both products

C. Line chart for Product A and Pie chart for Product B

D. Scatter plot for both products

Solution

1. Step 1: Understand combo chart types

   Combo charts combine different chart types, like columns and lines, to compare data sets clearly.

2. Step 2: Match chart types to products

   Product A as columns and Product B as a line fits Column for Product A and Line for Product B. Pie and scatter charts do not combine well here.

3. Final Answer:

   Column for Product A and Line for Product B -> Option A

4. Quick Check:

   Combo chart = column + line [OK]

Hint: Use column + line combo to compare two products [OK]

Common Mistakes:

• Choosing pie charts which can't combine well
• Using scatter plots which don't show trends clearly
• Mixing line with pie charts incorrectly

4. You created a combo chart but the line series is not showing. What is the most likely error?

medium

A. The line series is not assigned to the secondary axis

B. The data range is empty

C. The chart type is set to pie for all series

D. The worksheet is protected

Solution

1. Step 1: Check combo chart setup

   In combo charts, line series often need to be on the secondary axis to display properly.

2. Step 2: Identify the missing line issue

   If the line series is not assigned to the secondary axis, it may not appear correctly, causing it to be invisible.

3. Final Answer:

   The line series is not assigned to the secondary axis -> Option A

4. Quick Check:

   Line series needs secondary axis [OK]

Hint: Assign line series to secondary axis to show it [OK]

Common Mistakes:

• Assuming empty data range is the cause without checking axis
• Setting all series to pie chart type
• Thinking worksheet protection hides chart series

5. You want to create a combo chart showing monthly revenue as columns and profit margin as a line on a secondary axis. Which steps should you follow?

hard

A. Select data > Data tab > Sort by revenue and profit margin

B. Select data > Insert > Pie Chart > Add profit margin as line

C. Select data > Insert > Line Chart > Change revenue to pie chart

D. Select data > Insert > Combo Chart > Set revenue as column, profit margin as line on secondary axis

Solution

1. Step 1: Choose correct chart insertion method

   Use Insert > Combo Chart to combine column and line charts for different data series.

2. Step 2: Assign chart types and axes

   Set revenue as columns and profit margin as line, assigning profit margin to the secondary axis for clarity.

3. Final Answer:

   Select data > Insert > Combo Chart > Set revenue as column, profit margin as line on secondary axis -> Option D

4. Quick Check:

   Combo chart with secondary axis for line [OK]

Hint: Use combo chart and assign line to secondary axis [OK]

Common Mistakes:
