Trace Scale:
You can set the upper (Max) and lower (Min) limits of the horizontal scale (time,
energy, channels depending on nature of data) and have a distinct interval out of the
entire trace displayed. You can also set a Unit string for the horizontal axis. E.g. for
a sonic trace it would be [µsec], for an energy spectrum it could be [keV].
Amplitude (vertical) scale and unit as well as Trace (horizontal) scale and unit displayed in log title
Check the Display Grids option to draw vertical grid lines using the specified step.
Display As:
Sonic data traces can be displayed as Wiggle lines, black and white variable density
line (B/W vdl) or you can color code the amplitudes and display the traces as Color
vdl.
Wiggle line (left), B/W vdl (middle) and Color vdl display
Shading:
If the wiggle line display has been chosen for the data display you can shade the
positive and negative amplitudes with different colors. Additionally you can shift the
base line (Zero Line), which is usually at zero, so shading will be applied to the
