Bitmap Plot

This allows parameters such as the baseline and offset of the bitmap spectrum to be altered. For more information on altering these parameters, see the section on bitmap overlays.

Settings

Units	Horizontal Axis units.
IntensityUnits	Selects vertical units for plot. If you use "Arbitrary" or "Squared" here, then the plot will always be scaled to the full range available, unless AutoMin or AutoMax are not set
Colour	Colour for plot.
Hide	Set to hide this plot
ZeroValid	Set if zero in data is correct.
AutoMin	If set, Ymin automatically updated to minimum point in plot range
AutoMax	If set, Ymax automatically updated to maximum point in plot range
`FixCentre`	Apply FrequencyScale so that centre does not move if set
Xpixel1	Horizontal Pixel corresponding to Frequency1
Xpixel2	Horizontal Pixel corresponding to Frequency2
BaselinePixel	Vertical Pixel corresponding to BaselineIntensity
MaximumPixel	Vertical Pixel corresponding to MaximumIntensity
TopLeftX	Bounds of active region for plate scanning - see Tracing Plate Spectra
TopLeftY
TopRightX

BottomLeftX

Parameters

FrequencyOffset	Frequency offset used when displaying plot.(This is not the same as "Offset" in the constants window (and in the main window), which changes the frequency offset of the simulation.)
`FrequencyScale`	Scaling factor for frequency; see also FixCentre
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
Frequency1	Frequency at Xpixel1.
Frequency2	Frequency at Xpixel2.
BaselineIntensity	Intensity at BaselinePixel - normally 0.
MaximumIntensity	Intensity at MaximumPixel - normally 1.
PlateAngle	Angle of lines on plate with respect to vertical - see Tracing Plate Spectra
