Produce charts and graphs from given information
Charts and graphs are used to convey information.
Charts are generally set out in a table form. In the manufacturing, engineering and related services industries charts are used to show, for example, different thread forms, recommended rotational speeds for a lathe, etc.
A graph is a diagram used to organise data (numbers) so the data is easier to understand.
All graphs should have:
- appropriate and correctly labelled axes
- clear and accurately marked coordinates
- clearly marked, appropriate limits
Features of good graphs
The following diagram highlights features of good graphs.
