Pollen data are stored in tables, with taxa in columns and samples (spectra) in rows. Such tables, typically are stored in spreadsheets (MS Excel), however it may have simple form of text, with values separated by tabulator (txt files) or by semicolon (; csv files). For storing and printing of smaller tables (to 30-50 taxa) also text editors (like MS Word) may be used. In case of any of mentioned forms, and probably of some other, it is enough to copy the table to the Clipboard (Ctrl-C) and then, to click the menu option "Load table from Clipboard" in the described here application, to have data ready for diagram plotting.

Shown below application Diagram is a part of system PolPal (Walanus 1989, 1994, 1995a,b; Walanus & Nalepka 1997, 1999; Nalepka & Walanus 2003), used for counting pollen, diagrams plotting, numerical analysis (ConSlink, PCA, Rarefaction, Sample Similarities Matrix), dating spectra (on basis of a 14C dates), and isopollen maps plotting (Ralska-Jasiewiczowa et al. 2003). Presented application, however, is independent of the system, since data may be flexible taken on from almost any typical application.

The final result, the diagram, is in the standard MS Windows format of bitmap (*.bmp file). It is very easy to add some additional descriptions, lines etc. to bitmap. Printing bitmap is easy as well, simply because it is standard format. Even the diagram of 300 taxa and 300 samples may be printed with very good quality (see for example Ralska-Jasiewiczowa et al. 1998).

A few examples of diagrams are shown below (some figures are sized down).

With taxon name an additional information can be transferred to the program. Namely Alnus#tg3 means, that taxon Alnus is a tree, the curve is to be of colour "g" (defined in the program), and that taxon is to be the third in the diagram. That three parameters are optional (one only letter is treated as life form - used in pollen sum definition).

There is no limit to taxon name length (Myriophyllum spicatum/verticillatum); taxa names can be edited in the program (as well as taxa color and position), during process of diagram adjusting.

Maximal number of taxa =350, the same is maximal number of samples. Since MS Excel has only up to 256 columns, text file (txt or csv) is to be used in case of more taxa.

In the first column the sample depth is given (or age), which define sample position in the diagram.
