upper and lower scale limits.
Be aware that changing the horizon trend scale can change the angle of the trend indicator, without the

If a measurement exceeds the outer limits of the scale, the wave will be clipped and you must either
reset the horizon or the horizon trend scale to display the values outside the scale limits.
