Time series graph:
- The illustration of data points at successive time intervals is known as time series graph.
- For example, in a trade cycle or in cycles of economic activities, short term and long term regular or irregular (erratic) changes are observed. The trends of such changes are obtained with the help of statistical tools.
- Graphs drawn by taking these changes as variables and plotting the values of these variables over time as data points are called time series graphs.
