The View window

\begin{figure}\centerline{\epsfig{file=view-window}}
\end{figure}
Open this window using \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~View...~} in WAVE 's main window.

Show
Toggle these options by selecting them. Multiple annotation fields are shown in the following arrangement:
annotation mnemonic
subtype
chan field
num field
aux field
Signal names and baselines are defined in the header file for the current record. Markers show the precise locations of all annotations. Levels show the amplitudes of each signal at the time indicated by the pointer, whenever a mouse button is depressed. The Level window appears at this time.

Time scale:  \Ovalbox{\small\sf \ensuremath{\nabla}}
Set the horizontal scale for the signal and Scope windows by selecting one of the choices.

Amplitude scale:  \Ovalbox{\small\sf \ensuremath{\nabla}}
Set the vertical scale for the signal and Scope windows by selecting one of the choices.

You can check the calibration of the display by enabling the 0.2 s x 0.5 mV grid, and then by measuring the spacing of the grid lines. If the spacing is incorrect, your X server does not know the actual display resolution. See your X server documentation if this is the case, or use the -dpi option when starting WAVE (start WAVE with no arguments for instructions).

Draw:  \Ovalbox{\small\sf \ensuremath{\nabla}}
Use this control to toggle WAVE 's signal display mode. By default, WAVE displays all signals in order of signal number, with signal 0 at the top of the signal window. If you select listed signals only, WAVE displays only those signals that appear in the signal list (in the Analyze window, from top to bottom in the order in which they appear in the signal list).

Show annotations:  \Ovalbox{\small\sf \ensuremath{\nabla}}
Use these menu buttons to choose how annotations are to be displayed. By default, WAVE displays annotations in the center of the signal window. If you select attached to signals, each annotation appears near the signal specified by its chan field. If you select as a signal, WAVE draws a signal derived from the num fields of any annotations in the window, in place of the standard annotation display. The right-hand menu button allows you to choose if the full texts of closely-spaced annotations should be shown even if they overlap (if you choose allow overlap). By default, the texts are truncated after the first character if they would overlap, to improve legibility.

Time display:  \Ovalbox{\small\sf \ensuremath{\nabla}}
By default, WAVE displays elapsed time from the beginning of the record in hh:mm:ss format. Use this control to select display of absolute time (if defined for the record), or to display time in sample intervals. If you select absolute time display, you may enter absolute times in the Find window.

Grid:  \Ovalbox{\small\sf \ensuremath{\nabla}}
Use this menu button to select a grid style, or to suppress the grid display.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Undo changes~}
This button cancels any changes you have made to the View window settings and restores the indicators to reflect the current settings.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Redraw~}
This button causes WAVE to accept any changes you have made in the View window. Pressing \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Redraw~} dismisses the View window and refreshes the signal window.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Save as new defaults~}
This button preserves the current settings within the View window in your home .Xdefaults file.
