Stretch a chromatogram
The stretch function allows you to perform a two-point
contraction or expansion of chromatograms relative to
another. To stretch a chromatogram,
1. In the chromatogram window, do a right mouse click
and then select Operations followed by Stretch.
2. Select points (or peaks) on the first chromatogram to
which the second will be stretched (or contracted).
3. Select two points on the second chromatogram. The
chromatogram between these two points will be
stretched or contracted to fit the two points specified
on the original chromatogram.
To un-do the stretch,
1. In the chromatogram window, do a right mouse click
and then select Properties. Click the Trace Setup
tab, then scroll to the right to the X-axis and Y-axis
offset columns where you can delete or change these
settings. Click the Reset Scaling button to restore
ALL settings to their original values.
