Peak Interactive Data Display

Peak display features let you visually examine spectra in many modes, and with complete interactive expand, roll and zoom and autoscaling.

spectral display

At the bottom of each data window is a row of icons that control the display format.

Spectral display in Overlay Mode

Spectral display in Offset Mode

In this mode, individual spectra can be dragged to position them where needed.

Spectral display in Stack Mode

Each spectrum is displayed in its own layer

Spectral display in Superimpose Mode

This is especially useful when zoomed in on spectral regions as it puts spectra on a common y-axis scale

This plot is in overlay mode This plot is in superimose mode
Display before superimpose Display after superimpose

The interactive 3-D data viewer

The surface plot can be rotated. Clicking on the Contour plot will display the spectrum (absorbance vs wavenumber) and slice (absorbance vs time/distance) at those coordinates
