A time axis defines the time in the graph of the time course. This is done by the following steps.
- Enter the start time and press Set time. Unit of time has no meaning (just in this version) and is assumed to be years.
- Put end time (End Time) at the end of the last time interval, in this case the end of 2014 = 2015. Press Extend Axis.
The end result can be seen below. The figure shows the time axis to be used for time course.
