  • Time Series Graph
    A visual tool for displaying how a variable's value changes across time intervals using plotted coordinate pairs.
  • Coordinate Pair
    A set of two values representing a specific time and its corresponding measured value on a graph.
  • X-Axis
    The horizontal line on a graph that represents the passage of time, such as months or years.
  • Y-Axis
    The vertical line on a graph that shows the measured value for each time interval.
  • Trend
    A pattern in data indicating periods of increase or decrease over time, visible through connected points.
  • Increase
    A segment of data where values rise as time progresses, shown by upward movement on the graph.
  • Decrease
    A segment of data where values fall as time progresses, shown by downward movement on the graph.
  • Segment
    A straight line connecting two plotted points to highlight changes between consecutive time intervals.
  • Scale
    A system for labeling axes to ensure the entire range of time and values is visible and accurately represented.
  • Interval
    A specific span of time, such as a month or year, used to organize and measure data points.
  • Data Table
    A structured arrangement of values and time intervals used to verify plotted points on a graph.
  • Span
    The total range of time covered by the data, from the first to the last interval.
  • Value
    The measured quantity at a specific time, plotted on the y-axis for each coordinate pair.
  • Label
    A descriptive marker on an axis that clarifies what is being measured or tracked.
  • Period
    A continuous stretch of time during which a particular trend, such as increase or decrease, is observed.
