Parameter settings (for chromatogram signal colors and line width) will be taken from the global setting in the User Options - Signals & Curves dialog (accessible from the
Sets colors back to those fixed at the initial installation of the station. Set Initial Colors button is disabled when option Use User Options is checked.
When checked, all signals available in the Chromatogram window save the active one will be greyed out.
Automatically sets a scale on the vertical axis.
Preserves common axis for all displayed chromatograms (signals). Two alternatives may be selected:
Scale to All Signals - The scale will be set so that all the displayed signals fit into the window according to the minimum and maximum value of all displayed signals.
Scale to Active Signal - The scale will be set according to the active signal.
MS Offsetting - Specific display for the MS Extension - signal ratios are left untouched, but the individual signals are offset to start at the same height visually. This means the scale on the Y axis is the same for all signals, but the offset is individual for different signals. This allows to disregard the background noise on some signals (namely on TIC).
Enlarges or reduces each signal so that they fit, full height, into the graph. Using this method will eliminate the mutual proportions between the various signals and each signal will have its own scale on the vertical axis.
The upper limit for scale for displaying the chromatogram (signal) will be derived from:
Maximum value - maximum value of signal.
Largest peak - highest integrated peak.
2nd largest peak - second highest integrated peak.
3rd largest peak - third highest integrated peak.
Maximum baseline value - maximum value not belonging to any identified peak (useful for negative chromatograms with positive spikes).
The lower limit for scale for displaying the chromatogram (signal) will be derived from:
Minimum value - minimum value of signal.
Largest negative peak - highest negative integrated peak.
2nd largest negative peak - second highest negative integrated peak.
3rd largest negative peak - third highest negative integrated peak.
Minimum baseline value - minimum value not belonging to any identified peak (useful for chromatograms with positive peaks and negative spikes).
List of open chromatograms
Provides a list of all chromatograms (or signals when multi-detector chromatograms are in use) displayed in the right-hand section of the tab. If less than 32 chromatograms are open, the list is supplemented by the #X unassigned fields, enabling the color of further chromatograms to be defined without having to open them.
Caution:
All fields in the right-hand section are valid only for the chromatogram (signal) selected in this field.
Displays/hides selected chromatogram. This does not close a chromatogram meaning that all the data remain valid (i.e. the results table). It is possible to hide an active chromatogram.
Displays/hides descriptions and lines joined to the chromatogram. Descriptions and lines joined to the working area (Workplace) remain unchanged (to hide these use the Show Workplace Labels command from the Graph tab).
Width of chromatogram curve in points. Line Width option is disabled when option Use User Options is checked
Selects the color of a chromatogram.
Color… - Selects user desired color. Color... button is disabled when option Use User Options is checked
Shifts chromatogram in currently set units.
Enlarges or reduces chromatogram in time or voltage axis. The permitted values range is between 0.01-100.
Note:
The X Offset and Y Offset fields correspond to the Move command, and the X Scale and Y Scale fields to the Scale command. These are performed by right-clicking the mouse within the graph and then using the Overlay - Move or Overlay - Scale command from the context menu (for more details see also chapter Overlay & Other)
Note:
The Offset and Scale operation are not stored in the current chromatogram, after opening the chromatogram again they will be reset to the default values. Only in case the chromatogram window is closed with some chromatogram opened, its offset and scale values will be restored after reopening the window.
Sets original values (i.e. Offset to 0 and Scale to 1).
