Previous Scaling: zooms to the previous time and amplitude range.

Each time you scale chromatogram(s), Interactive Graphics adds

the new scaling rectangle to the end of a list of scaling rectangles.

Previous scaling zooms the display to the value stored in the

previous position on the list. This item is disabled when at the start

of the list.

Next Scaling: zooms to the next time and amplitude range. Each

time you scale chromatogram(s), Interactive Graphics adds the

new scaling rectangle to the end of a list of scaling rectangles. Next

scaling zooms the display to the value stored in the next position

on the list. Since new scaling rectangles are added to the end of

the list, it implies that Next Scaling is only available when you had

formerly hit the Previous Scaling button. That is, this item is

disabled when at the end of the list.

Exact View: opens the Exact View dialog which lets you specify the

time and amplitude ranges numerically.

Cursor Display: turns the cursor on or off. The cursor follows the

active trace and displays the time and amplitude of it current

position in an “info-panel”. As you move it near a peak event, it

jumps to the peak event and “sticks” to it. If the peak event

represents a reported peak apex, then the “info-panel” also

displays information such as the peak name, area, and width.

Hold the shift key down to disable the “stickiness” feature so that

the cursor follows the trace smoothly and is not affected by peak

events.

Hold the control key down to allow the cursor to move anywhere on

the screen without following the active trace.

Select Background Color: opens the standard Windows Color

dialog so that you can select a new background color for the

window. With a dark background color, Interactive Graphics

automatically chooses white as the color for axes, info-panel, etc.

text. With a light background color, the text color is automatically

set to black. Select “Display Faded Background” so that the

selected color fades to a lighter color from the bottom to the top of

the window. When solid black or white is selected, the fading does

not occur.

Tile Chromatograms: displays chromatograms one above each

other with each chromatogram in its own non-overlapping section

in the main window. In tiled mode, the time axis for all

chromatograms is always the same.

Overlay Chromatograms: displays chromatograms on top of each

other so that portions of each chromatogram overlap ones that are

visually behind them. In this mode, each trace may be offset from

others (as specified in the offsets tab of the preferences dialog) to

provide a 3-D view of the data.

Lock Zoom (tiled mode): when depressed, locks the amplitude

scaling so that changing the amplitude scaling in one

chromatogram causes all other chromatograms to also display the

same amplitude range. When not depressed, the amplitude range

of the individual chromatograms may differ.

Fill Peak Mode: opens the Fill Peak Table Window which allows

you to quickly build a peak table using peaks from the current

chromatogram. In this mode the cursor is automatically displayed

and locks on to the nearest peak apex. Clicking adds a new peak

table entry. If you check the “Fill table from selection” checkbox in

the Fill Peak Table Window, then all of the peaks in the region you

select are added to the peak table.
