2. Show a cursor and its associated “info-panel” containing the time and

amplitude of the cursor and peak information.

3. Display baselines and droplines.

4. Display peak names and retention times.

5. Show the Time Events that were performed by data handling.

6. Display a blank baseline.

7. Display peak events in the shape of a triangle.

8. Display the run file “info-panel”.

9. Use the scaling buttons from the Chromatogram Toolbar: Full Scale, Vertical

Full Scale, Horizontal Full Scale, Previous Scaling, Next Scaling, and Exact

View.

You can make an inactive chromatogram the active one, by clicking directly on

the chromatogram in the Main Window with the right mouse button and select the

Move to Front menu item from the menu displayed.

When in tile mode, all chromatograms are considered active, however, the

Chromatogram Toolbar buttons only apply to the chromatogram at the bottom.

Opening Data Files

Use the Open Multiple Data Files dialog box to provide a list of which Data Files

will be displayed in the Main Window. You can also use this dialog box to change

the order of already open chromatogram(s) which also has the affect of

displaying the trace in a different color.

Zooming and Scrolling

The primary purpose of the Main Window is to allow you to inspect sections of

the chromatogram and review the placement of peak events as determined by

data handling. To do this you may want view a part of the chromatogram in high

detail. You do this by zooming, that is, selecting a rectangular section of the

chromatogram by dragging the mouse in the Main Window. When you release

the mouse, the chromatogram is redrawn so that the selected area fills the entire

Main Window. You can zoom similarly by selecting a chromatogram section in

the Locator Window. By repeatedly selecting rectangles in the Main Window, you

view the chromatogram ever finer detail. Interactive Graphics will not allow

further zooming if the amplitude range would become less than 0.0001 and the

time range would become less than 0.05 minutes. Double clicking in the Main

Window displays the chromatograms at their full scale zoom levels.

“PowerZooming” is an alternative way of zooming. You PowerZoom by clicking

and holding the left mouse button down without moving it. This zooms in on that

point isometrically, or, if your are holding the control key down, zooms out from

that point. Once PowerZooming begins, you can move the mouse around while

the mouse button is still down to change the point at which you are zooming.

You can view other sections of the chromatogram while maintaining the same

zoom level by scrolling. Scroll bars are shown only if the time or amplitude range

of your zoomed view is less than the maximum time or amplitude range of the

chromatograms as determined by autoscaling. Scrolling horizontally lets you see

sections of the chromatogram earlier or later than the current section. Scrolling

vertically lets you see sections of higher or lower amplitude.
