  • Time Series Graph
    A visual tool that displays how a variable’s value changes at different points across a time interval using connected coordinate pairs.
  • Coordinate Pair
    A set of two values representing a specific time and its corresponding measured value, plotted as a point on a graph.
  • X-Axis
    The horizontal line on a graph that represents the progression of time intervals, such as months or years.
  • Y-Axis
    The vertical line on a graph that shows the measured value of the variable at each time point.
  • Trend
    A general direction in which data points move over time, revealing patterns like upward or downward movement.
  • Increase
    A period where the measured values rise as time progresses, shown by an upward movement on the graph.
  • Decrease
    A period where the measured values fall as time progresses, shown by a downward movement on the graph.
  • Segment
    A straight line connecting two plotted points, used to visually link data and highlight changes between time intervals.
  • Scale
    A consistent set of values on an axis that ensures all data points fit and trends are easily observed.
  • Interval
    A specific span of time, such as a month or year, over which data is measured and plotted.
  • Data Table
    An organized display of time intervals and their corresponding measured values, used as a reference for plotting.
  • Label
    A descriptive text on an axis that clarifies what variable or unit is being represented.
  • Value
    A numerical measurement recorded at a specific time, represented on the vertical axis of the graph.
  • Span
    The total range of time covered by the data, from the earliest to the latest interval.
  • Point
    A specific location on the graph where a coordinate pair is plotted, representing a value at a certain time.
