Make And Edit Spectrum Window Axis Types
The purpose of this popup window is to allow the user to create new types of axis for the display of spectra within windows. This requirement is relatively rare and under most circumstances the standard, default axis descriptions will not need to be changed. The popup is divided into three tabs which display different aspects of the spectrum display axis definitions.
The first “Axis Units” tab lists the different units of measurement that may be used in an axis. Although new kinds of axis may be created, only the ppm, Hz and “arbitrary” units are currently used by Analysis, i.e. spectrum windows only display standard NMR isotope axes and intensity for a “value” Y axis.
The “Axis Types” tab allows the user to specify new kinds of NMR data axis, for example to be able to work with spectra that have an isotope type that is not part of the normal Analysis setup. Clicking [Create] will prompt the user to specify the characteristics of the axis, and some of these can be adjusted after the initial definition. Under normal circumstances the only features that the user is likely to edit are the “Region”, “Decimal places” and “Peak Size” columns. The region describes the upper and lower bounds of the axis vales, and dictates the maximum extent of a spectrum window display when fully zoomed out; a spectrum window cannot display outside the bounds of its axes, however these bounds may be changed.
The “Panel Types” tab allows the user to create sub-categories within a given kind of axis. These are not used for very much, but are used with the 1D ruler lines, so that a line is only drawn on axes that share the same panel type. Accordingly, a ruler line drawn on an amide 1H axis (panel type “H1”) will not show on the indirect 1H axis (panel type “H2”). The user can create extra panel types if this kind of distinction is required, although “H1” and “H2” types are present by default. The panel type of a spectrum window axis is set via the “Windows & Axes” section of the main Windows popup.
