Meaning and scope

Definition

A chart showing changes in values with lines along axes. It does not guarantee forecasts causation or accurate measurement.

In more detail

It connects points along horizontal and vertical axes so the shape of change can be read. Values remain separate choices.

Includes

  • Charts showing change with axes and lines

Excludes

  • Valid forecasts
  • Proof of causation
  • Accurate statistical results

What this does not imply

  • Accurate measurement
  • Forecasts
  • Causation

Variability

Because the source is a weakly direct general reference, tick and value legibility may vary.

Usage and adjustments

Usage

  • Keep axes and lines corresponding
  • Specify values separately

Distinguish similar expressions

  • Verify numerical accuracy separately

Typical uses

  • Show change over time
  • Compare multiple trends

Possible failure modes

  • Lines detach from axes
  • Values are unreadable and changes can be misread
