Which of the following statement about charts is true?

The more data ink, the better

Data ink can sometimes help tell a richer story

We should make as many grids as possible in a chart

A useless chart is called "chart junk"

Expert Solution

1. The more data ink, the better.

This statement is true.

Reason: Data ink ratio = (Data ink)/ (Total ink used to print the graphic)

A good graphic should only include data ink. The highest possible data ink ratio is 1. Non-data ink has to be erased wherever possible to avoid dragging viewer's attention to irrevelant data.

2. Data ink can sometimes help tell a richer story.

This statement is true.

A graph with only data ink means that it has only the necessary data needed for effective communication.So data ink can sometimes help tell a richer story.

3. We should make as many grids as possible in a chart.

This statement is false.

Anything that is not necessary ,contributes to non data ink which should be erased. Using too much of grids may complicate the look and feel of a graph which is not recommended.

4. A useless chart is called "Chart junk".

This statement is false.

"Chart junk" is the name given to any unnecessary or confusing/misleading visual elements in a graph.

"Chart junk" is never used to refer any useless chart.
