This button activates a popup view window, Profile Viewer, which allows the user to see the Current Channel's longitudinal profile graphically. Moving the viewer cursor along the profile allows the user to obtain the station, elevation, and slope at any point indicated by crosshairs along the profile.
Vertical Exaggeration This toggle button setting allows the user to select profile views at fit, 1x, 2x, 5x, and 10x vertical exaggeration.
Drag Action This toggle button setting allows the user to select either zoom or pan drag action. Then the user selects the Zoom button, holding down the left-click button on the mouse as the mouse is moved will zoom in and out on the profile display. Similarly, when the user selects the Pan button, holding down the left-click button on the mouse allows the user to pan the profile in the display. Whether in Zoom mode or Pan mode, the middle mouse button can be held down to pan the profile in the display. Thus, if the user has a middle mouse button, staying in the Zoom mode and using the middle mouse button to pan is most efficient.
Grid Ticks Only This
toggle button setting allows the user to select either the default
x and y grid lines across the profile, or tick marks only on the
axes.
