Question

A coworker has been asked to give a report on customer satisfaction with your newly implemented technical support center. She is thinking about using a line chart to trace the increase in customer satisfaction over the last two months, but she would like some advice on how to use graphics appropriately. What advice should you give her?
1. Avoid plotting the first value when preparing a segmented chart.
2. Begin with a grid divided into squares.
3. Arrange the time components vertically on the left-hand side of the chart.

Answer 1

Answer:

2. Begin with a grid divided into squares.

Explanation:

This is a best approach because it allows for accuracy/precision. To successfully indicate the increase in customer satisfaction on a line chart, before anything else having grid divided into squares makes it easy for her to setup her scale for the two months customer satisfaction data.

After completing this phase, then she could proceed further with the drawing of line chart; which should indicate the rate of change in customer satisfaction on the vertical axis.
