C3.3.4.3 Time Series Plots



A time series plot or time based record is a visual way of showing how a particular measure varies over time. It is a sequence of data points, measured typically at successive times spaced at uniform time intervals, for example:

  • a critical dimension within a manufacturing process measured hourly
  • punctuality figures for a public transport operation recorded weekly
  • the FTSE index recorded on a daily basis
