The histogram is an example for the first case, here in the MGDLIT2001 file. It displays the distribution of publications in the field of Fourier transform microwave spectroscopy over the last decade. The display is based on the retrieval of the publication year interval between 1990 and 1999 and the keyword search FOURIERMW+NT, combined by means of the Boolean operator AND. Here FOURIERMW is the acronym of the corresponding keyword. The relationshipcode NT ("narrow term" automatically includes all more specific keywords of the given item, in this case "Fourier transform microwave spectroscopy of molecular beams", etc).

The scatter chart is an example for the second case. Without any retrieval all C-C internuclear distances of the complete MGDCOM2001 file are taken into account. The peaks at 1.20 Å, 1.33 Å, 1.39 Å and 1.52 Å can be assigned to acetylenic triple bonds, olefinic double bonds, aromatic bond and aliphatic single bonds, respectively.
