identifying the elements of a dual-axis cha
what is unique about a dual-axis chart?
○ data is coded with two different colors.
○ data is charted by two different types of data.
○ the information on the axis has two different fonts.
○ one set of data is shown two different ways.

Explanation:

A dual - axis chart is designed to display two different types of data (e.g., one in units and one in percentages) on the same chart with two y - axes (or an x - axis and a y - axis with different scales). Let's analyze each option:

• Option "Data is coded with two different colors": Color coding is not unique to dual - axis charts; many single - axis charts also use color coding.
• Option "Data is charted by two different types of data": This is the key feature of a dual - axis chart. It allows for the visualization of two datasets with different measurement scales or types (e.g., sales in dollars and sales growth in percentage) on one chart.
• Option "The information on the axis has two different fonts": Fonts on the axis are a matter of formatting and not a defining characteristic of a dual - axis chart.
• Option "One set of data is shown two different ways": A dual - axis chart is about two different sets of data, not one set shown in two ways.

Answer:

B. Data is charted by two different types of data.
