Units  Horizontal Axis units. 
IntensityUnits  Selects vertical units for plot. This has the same
possible values as for a simulation,
though the interpretation is slightly different:

Colour  Colour for plot. 
Hide  Hide this plot 
ZeroValid  Set if zero in data is correct. 
FixCentre  Select style of frequency scaling; see FrequencyScale below. 
AutoMin  If set, Ymin automatically updated to minimum point in plot range 
AutoMax  If set, Ymax automatically updated to maximum point in plot range 
TwoD  
FirstPoint  First point to use in fitting and plotting. (Note that the point number under the mouse is shown at the bottom of the overlays window). 
LastPoint  Last point to use in fitting and plotting. 
IsLineList  Set to treat data as a list of line positions, optionally with intensity. 
Convolute  Set to convolute experimental spectrum with simulation linewidth(s). 
ComponentType  (Future Use) 
FrequencyOffset  Frequency offset used when displaying plot. Note this is distinct from Offset in the constants window (and in the main window), which changes the frequency offset of the simulation. 
FrequencyScale  Scaling factor for horizontal scale. The correction
formula used is: If FixCentre
is set:
f ' = (ff_{av})*FrequencyScale
+ FrequencyOffset
where f_{av} is the
average of the highest and lowest frequencies. This means
that the centre of the plot only shifts by
FrequencyOffset, regardless of the scale used.
If FixCentre is clear (default): f ' = f*FrequencyScale
+ FrequencyOffset

Ymin  Lower end of current plot range; overwritten with lowest value in current range if AutoMin set 
Ymax  Upper end of current plot range; overwritten with lowest value in current range if AutoMin set 
Baseline  Baseline position. 
Scale  Vertical scale factor used in plotting. 
Gaussian  Width of Gaussian function to convolute plot
with.
