Marquee Zoom
Toolbar Buttons
You can use your mouse to marquee an area of data to zoom in on. Click and drag to marquee a
section. When you release the mouse button, the enclosed area will pan to the center of the
screen and them zoom in as much as possible while keeping the entire area on the screen.
We make extensive use of the right mouse button. Most functions have naturally paired
operations. Most paired functions are natural opposites (like left/right, in/out, first/last,
previous/next). Others are not opposites but still naturally paired (like X/Y). We take advantage of
this symmetry to double up the functions of most buttons and other clicks. This not only reduces
desktop usage but also results in more natural, easier to remember functions.
For example, rather than having separate SEARCH LEFT and SEARCH RIGHT buttons, we have
a SEARCH button. Left clicking the button will SEARCH LEFT; right clicking will SEARCH RIGHT.
After only a few minutes of use, this becomes much more natural than using separate buttons.
Switching directions involves pressing different mouse buttons rather than moving the mouse to a
new button in the application. All buttons in the tool bars to the right of the Waveform Views are
dual-function. Additionally, you will find that left and right clicking on the " < " and " > " symbols,
Active Marker column and various other buttons will perform similarly paired functions.
Left Click - Go to the Trigger Point Cursor
Right Click - Go to the midpoint of the X and Y Marker, then Zoom to Fit in view
Left Click - Go to the midpoint of the A and B Marker, then Zoom to Fit in view
Right Click - Go to the midpoint of the C and D Marker, then Zoom to Fit in view
Down Position - Waveform views are LINKED for Synchronized Scrolling (first graphic above)
(and the screen center). This allows you to walk through the data without continually
re-centering the screen. It also supports our 'bring the data to the center..THEN zoom'
paradigm.
Note that this is an intelligent TACK. It does NOT freeze the marker at the screen center. It
brings the marker to center any time you move the marker (by dragging, snapping or
setting its position). This allows the marker to stay at a specific TIME/EDGE if you scroll the
screen or jump to another marker. The next time you attempt to move the TACKed
marker, it will move relative to the place you left it, then bring it and the data to the window's
center. For example, we will assume that you have enabled the Tack option for both X and
Y markers. While you are moving/snapping the X marker, it stays as the center. You can
jump to the Y marker and it starts tacking at the center. At any time, you could jump back to
the X marker.
