The graph shown here highlights the effects of altering the reference temperature which is very useful as each application has its own unique operating temperature range/temperature of most importance. For example, by adjusting the reference temperature and resistance in the PARAMS field of the NTC Thermistor model to a higher nominal temperature point, the resulting output minimizes the voltage variation at higher temperature (i.e. essentially shifting the larger portion of the tolerance to 25°C).
