Question

What is purpose of using charts and graphs

Answer 1

Explanation:

Charts

The main functions of a chart are to display data and invite further exploration of a topic. Charts are used in situations where a simple table won't adequately demonstrate important relationships or patterns between data points.

Line Graphs

One of the graphs you will likely use most often is a line graph.

Line graphs simply use a line to connect the data points that you plot. They are most useful for showing trends and for identifying whether two variables relate to (or "correlate with") one another.

Examples of trend data include how sales figures vary from month to month, and how engine performance changes as the engine temperature rises.
