Now, imagine that you want to zoom in on t = 60 seconds.
The canonic tick, at t = 0, does not appear on the graph but it still controls major tick locations.
User Ticks from Waves
With Computed Manual Ticks you have complete control over ticking as long as you want equally-spaced
ticks. If you want to specify your own ticking on a log axis, or you want ticks that are not equally spaced,
you need User Ticks from Waves.
The first step in setting up User Ticks from Waves is to create two waves: a 1D numeric wave and a text
wave. Numbers entered in the numeric wave specify the positions of the tick marks in axis units. The cor-
responding rows of the text wave give the labels for the tick marks.
Perhaps you want to plot data as a function of Tm/T (melting temperature over temperature, but you want
the tick labels to be at nice values of temperature. Starting with this data:
you might have this graph:
