Full Zoom
Reduces both the x axis and the y axis on the active graph.
Therefore, the zoomed-in area expands to fill the entire graph.
To zoom in on a portion of the trace, click the toolbar's Full
Zoom icon. Next, click and drag to draw a rectangle on the
desired portion of the trace. If you make an error while zooming
in, click the Auto Scale icon to restore full view.
Horizontal Zoom
Zooms the wavelength span on the active graph. Therefore, the
chosen wavelength area expands to fill the entire display.
To zoom in on a portion of the trace, click the toolbar's
Horizontal Zoom icon. Next, click and drag to draw a rectangle
on the desired wavelength portion of the trace. If you make an
error while zooming in, click the Auto Scale icon to restore full
view.
Once you are viewing the minimum possible span, attempting to
zoom further will attempt to center the viewable range on the
center of the area dragged on with the mouse, but the span will
remain the same.
Vertical Zoom
Zooms the y axis span on the active graph. Therefore, the
zoomed-in area expands to fill the entire graph.
To zoom in on a portion of the trace, click the toolbar's Vertical
Zoom icon. Next, click and drag to draw a rectangle on the
desired vertical portion of the trace. If you make an error while
zooming in, click the Auto Scale icon to restore full view.
Pan
Moves the entire trace on the active graph with the motion of
the mouse pointer. Click the Pan icon and then click on the
graph. This function is useful when you zoom in on a portion of
the trace, and need to quickly view another portion.
