3. Given this data in cells A1:B4:
A1: Month, B1: Sales
A2: Jan, B2: 100
A3: Feb, B3: 150

5. You have sales data for 12 months in columns A and B. You want to create a bar chart that shows sales by month horizontally and highlight months with sales above 100 in a different color. How can you achieve this in Excel?

hard

A. Create a bar chart, then use conditional formatting on the chart bars to color above 100 differently.

B. Create a pie chart and use slice colors to highlight sales above 100.

C. Create a column chart and manually change bar colors for months above 100.

D. Create a bar chart, then add a helper column with IF formula to separate above 100 sales, and plot both series with different colors.

Solution

1. Step 1: Prepare helper column with IF formula

   Create a new column with formula like =IF(B2>100,B2,NA()) to isolate sales above 100.

2. Step 2: Create bar chart with two data series

   Plot original sales and helper column as two series; Excel will show bars in different colors automatically.

3. Final Answer:

   Create a bar chart, then add a helper column with IF formula to separate above 100 sales, and plot both series with different colors. -> Option D

4. Quick Check:

   Helper column + two series = color highlight [OK]
