The WindView tool bar and the event pop-up menu provide two ways to control the interval displayed in the view graph. (These controls are also available in the main menu bar.)

Figure 5-2 shows the WindView tool bar. You can zoom in and out to show a shorter or longer time interval using the (zoom in) and (zoom out) buttons on the tool bar. The zoom factor drop-down combo box ( ) allows you to specify how far the display zooms each time you click a button. The default is 2; shows you half the current view and shows you twice the current view. To change the zoom factor, type a number in the box or select one from the drop-down menu. To return directly to a display showing the entire log, press the button (zoom 100%). To select a specific interval, click and drag over the interval and then press .    

The other tool bar buttons allow you to control what data is displayed and to generate analog data associated with your event log. For more information, see 5.6 Filtering for Data of Interest and 5.5 Viewing Analog Information.

Figure 5-3 shows the event pop-up menu. Right click anywhere on the view graph to open it. The menu provides Zoom In and Zoom Out options, plus a Zoom menu with multiple options including 100%. You can select a specific interval by clicking and dragging, then clicking Zoom In.    

Use Refresh whenever you need to update the view graph display.

Selecting Context State brings up the Context State Information window (see Figure 5-4), which displays information about the context closest to where the cursor was located when the menu was called. Selecting Show Event brings up the Show Event dialog box for the closest event (see Figure 5-8).   

The Help command in the event pop-up menu is a shortcut into the WindView online Event Dictionary; it displays the detailed description for the event nearest the point in the view graph where you right-click to bring up the menu. (For more information on the event dictionary, see B. Event Dictionary.) The Legend command is a shortcut to the summary descriptions of WindView event icons and state stipples (see Figure 5-9).
