Assignments Properties

To change the properties of the Assignments labels, double click on the spectral window and select 'Assignments' in the left tabbed menu. Once there you will be able to select the color, line width, font, background, frame, form and margin of the labels (with the capability to display the correlations):

If you have several compounds in your document, you can use the same color compound for the assignments labels (green and blue in the example below) by checking the applicable box:

You can find a tutorial about handling mixtures, here.

You can hide the assignments in a spectrum by unchecking the 'Assignments' box (or lines boxes for 2D) in the Assignments Properties. You can also do the same by right clicking on the molecule and selecting the applicable option:

The same effect will be obtained by right clicking on the 'Linked Spectrum' from the Assignments table and selecting 'Disable Link':
 

From the Properties, you could also customize the format of the assignments labels. The default configuration is "$n$$H$-$n$$V$", showing only the nucleus symbol and atom number from both dimensions. The info about the configuration format is shown in the tooltip.

You can display the assignments chemical shifts values in the molecular structure, just by adding the applicable macro from the Molecule Properties dialog box. In the example below, you can see some 13C assigcments added to the molecular structure.

When you have more than one assignment to the same atom, you can use the 'Multiple Display' parameter to show the assignments as a list (when no value is added), as a range (when setting rng) or as an average value (when setting avg).
